How to replace a light switch with a switch/outlet combo

Do you have a light in your home that just sits there unused? Do you need more outlets in a room or in your whole home and would like to use a light switch and turn it into an outlet that you need to use? Using a light switch can be useful because you do not need to redo all of the wiring to get it done. Just a few simple changes will be enough.

It is possible to turn a light switch into an outlet. By taking the right precautions and being careful when switching a few wires around, you can easily turn any light switch in your home into an outlet. Let’s take a look at how to do this process in your home.

Can I Make My Light Switch Into an Outlet?

Yes. It is possible to take a light switch in your home over to an outlet. If there is a light somewhere in your home that doesn’t seem to go anywhere, or you no longer use the light, then you may be tempted to change it over to an outlet that you can use instead. The process for converting your light switch over to an outlet is easier than you may think.

If you have some kind of light fixture in your home that you do not use, it may be a good idea to switch it over to an outlet. This is easier to do than many homeowners realize. You can even keep the light fixture and the switch and add in an outlet under it all. There are a ton of options available and it is possible to turn that light switch into an outlet if you choose.

How to Turn the Light Switch Into the Outlet?

Now that we know it is possible to do this, it is important to see what steps are necessary to turn that regular light switch over to an outlet. The steps include:

Find the Live Wire

One of the first steps that you should take before starting the replacement procedure is look around and find the breaker panel. This is inside the main panel and you need the one that will control the switch you plan to work on.

This needs to be turned off to keep you safe. Once the switch is turned off, you need to take the cover plate off and spend a moment testing the wires to see if they still give off any voltage. A voltage tester will help you see if this is a problem.

How To Test For A Live Wire

To test whether the breaker is off, you can turn on the switch you plan to do the work with and then place one lead of the tester on either of the black wires that are there and connect over to the switch. Place the other end of the tester on the green ground screw.

If you get any reading on the meter that is above zero or a light to show up when you do this, the circuit is still live. You need to turn off more breakers and not do any more work until you end up with a zero reading on the tester or the light on the tester no longer turns on.

Test The Terminals At The Light Switch

Once the right breaker is done, you can turn the breaker back on again before turning off the switch. Use the tester again to check out both terminals for power, using the same procedure we discussed above. One of the terminals is live and the other is dead here. Turn the breaker back off again. Then mark the live wire with some tape so you can remember it as you get to work through our next steps.

Steps For Converting the Switch Over to an Outlet

Remove Black Wires From Light Switch and Cap

Once you are done with the steps above, it is time to remove the black wires from the switch. Then take the wire cap and screw it onto the dead one before pushing it back into the box there.

This just helps keep everything out of the way for now. You do not want any exposed wiring to show up under the cap. If this does happen, you risk touching it with another wire or with your tools.

Remove Neutral And Ground Wires and Cap

From here, it is time to unscrew and then remove your ground wires. Make sure to separate them and then isolate the one wire that belongs to the cable that is the live hot wire. You can then untwist the white neutral wires that are inside the box, capping the one that is the same and belongs with the hot wire capped before.

At this point you should have a green ground wire, a white wire, and an uncapped black wire. Double check that all of these belong with the same cable.

Connect Wires To Correct Terminals on New Outlet

Now it is time to connect the black wire over to the brass terminals that come with the new outlet and the white wire that will then correspond to the chrome terminal.

A Note About GFCI Outlets?

Unless you plan to install a GFCI outlet, you get the choice of connecting these to either the lower or upper set of terminals. If you are doing the GFCI outlet, you need to connect them to the terminal that says LINE.

Connect Green Ground Wire

Finish all of this up with the ground wire. This wire needs to go over to the green ground screw. Make sure to screw it into the outlet and the box, and then add the right cover plate over all of it to keep the wiring inside.

Turn Circuit Breaker Back On

The very last step is to turn the circuit back on at the breaker panel. When this is done, you have successfully taken the light switch in your room and turned it into an outlet that you can use for anything!

I live in Minnesota, in a house that was gutted and rewired within the past 5 years. There’s a big closet I’m converting into a reading room. It doesn’t have a wall outlet, but does have a light switch. I was hoping I could replace the light switch with a switch/outlet combination.

The existing switch has two hot black wires going to it. The box also contains a pigtail of white wires and a pigtail of grounding wires. (Pictures below)

Does this seem like a possibility? If so, how would I wire the switch/outlet combination?

The two wires from the old switch go on the two top screws, hot on left and switched hot on right.

Add pigtails to the black and white and ground bundles with the wire nuts.

Black goes on hot side (left bottom screw).

White goes on right bottom screw.

Bare copper goes to green screw.

If there is metal link between the two screws on the hot side, then you could leave off the pigtail on the top screw.

How to replace a light switch with a switch/outlet combo

A switched outlet needs exactly the same 3 wires as a smart switch:

  • always-hot so the switch has something to switch, and for the receptacle
  • Neutral to power the smart switch itself, or the return for the receptacle
  • Switched-hot because that’s what the switch sends to the lamp.

Any switch already has always-hot and switched-hot, because that’s what switches do. As for neutral, look in the box and there it is – one single bundle that’s all-white. Don’t disturb any other wires in there.

Neutral connects to the only place it can, notably a silver screw. Always-hot will be shared. Though honestly, just guess. If you mix up the two hots, the only thing that’ll happen is the receptacle will be switched. In that case, swap the hots.

And ground of course, we don’t mention grounds because it’s not an active circuit wire (we hope) and it’s very simple to hook up (all grounds connect to all grounds).

I have an older house that has a single pole light switch in the bathroom.

it powers a single bulb vanity light above the mirror.

I would to replace it with a switch and GFCI outlet

there is just a black and white wire currently on single pole switch.

Is this something that can be done by either me or an electrician without costing too much?

if you need more info about my current wiring please let me know.

1 Answer 1

No. With just what you have now it is 100% impossible. Right now you have a switch loop which is just a constant hot and a switched hot. Even though one wire is white there is NO neutral in this box, both are being used as hots.

You could run a new cable to this box, but you best bet BY FAR is to have a circuit run to a new GFI receptacle and just leave the existing switch alone. This is almost certainly the only code legal way to go as well. Adding a new receptacle to an existing lighting circuit in a bathroom would not meet code and will almost certainly be inconvenient due to circuit overloading.

How to replace a light switch with a switch/outlet combo

Throughout your home, you will have different electrical needs. As a result, you might find yourself with a room that has switches in a spot where an outlet would be far more practical. If you’re not a trained electrician, it’s easy not to know what you can and can’t do when it comes to the electricity in your home.

Can a Light Switch Be Converted to an Outlet?

Yes, you can convert a light switch to an electrical outlet. However, because outlets and light switches have different functions, the wiring for one or the other will be different enough that you should trust a licensed electrician, such as Mr. Electric, to handle the project for you.

How an Electrician Will Change a Switch into an Outlet

Your first two choices are deciding whether to keep the switch and how you want the new outlet to function. Although you might not often use the existing light switch and think an outlet would better suit your needs, totally removing the light switch may not be the best course of action. Luckily, you don’t have to decide between outlet or switch, as you have options that will give you both outlets and switches. You can have your electrician wire the outlet so that the switch controls it, or the outlet can operate independently of the switch.

Anything related to electrical wiring is not a good candidate for a DIY home project. The inherent danger of working with electricity and the possibility of wiring an outlet incorrectly are not worth the risks. Here’s how your local Mr. Electric would install an outlet where your light switch is:

Identify which circuit the switch is on and turn off the power supply to that circuit to prevent electrocution.

Remove the switch from the wall and label the wires connected to it. The general rule for electrical wire color codes is that the red and black wires will be the live wires while a white wire will be neutral, but it’s possible that another color may be used.

Connect the wires to the proper terminals on the outlet. All wires must be attached correctly for the switch to work properly. This is something that a trained professional can do for you. A potential problem could arise if the person who originally installed the switch connected the wires incorrectly; if you replicate what was done previously, you will end up with the same faulty wiring job.

What Can Go Wrong When Turning a Light Switch into an Outlet?

Electricity makes life easier and more convenient, but wiring done wrong can lead to tragic consequences. Take a second to consider these common negative outcomes of DIY conversions before trying to convert your light switch to an outlet.

A combination light switch/outlet not always being on. If you’re not trying to fully replace a light switch with an outlet, a combo light switch and outlet can help give you the best of both worlds. However, if you don’t properly wire this fixture, you’ll end up with an outlet that only turns on with the switch, which might defeat the purpose of having both.

Accidentally reversing the hot wires and the neutral wire. This is one of the most dangerous outcomes you might come across. When you replace a light switch with an outlet and don’t connect the wires properly, you can create shock hazards.

Electricians Who Can Help You Change Your Switch to an Outlet

If you’re looking to increase the number of outlets in a room, converting your light switch to an outlet can be a great solution. But messing with electrical wiring and outlets can be a dangerous task, even if you’re an experienced DIYer. To ensure your electrical work is done properly and safely, contact the pros at your local Mr. Electric. Schedule an appointment or call us at (844) 866-1367 today.

Lately I have had many site visitors asking me to write an article on how to wire a duplex switch and receptacle combination device. While the switch/receptacle combo device is not common in the home, they have several unique applications where they can be very useful!

As with any electrical project, make sure that you take all necessary precautions, most important being to make sure you shut off the power. Always review the safety page on our website.

Another valuable resource available on our site is “The Basics of Household Wiring DVD”, which is also available as an instantly downloaded e-book. Follow this link to get your copy.

The switch/receptacle combo device is set up like a duplex receptacle, but has a 15A single-pole switch in one half, and a single 15A, 125V receptacle in the other half. They can work in conjunction with one another, or they can be connected and used independent of each other.

Here is a diagram showing the internal function of the switch/receptacle combination device.

How to replace a light switch with a switch/outlet combo

Here is an actual picture of a Leviton Switch/Receptacle Combination Device.

How to replace a light switch with a switch/outlet combo

I will discuss three different possible scenarios where a switch/receptacle combo device such as this would come in handy.

Scenario #1

In your garage or shop, you would like to install a task light, like a florescent light fixture over workbench. However, the walls are all finished so getting a new wire to a switch and then up to the light is not that simple. However, you have a receptacle just above the bench that you can get your power source from.

You can change this duplex receptacle to a switch/receptacle combination so that you still have power in the outlet, but can use the switch to control your new overhead task light. Fishing in a wire from the receptacle to the light fixture is fairly easy, so this is how you would wire the switch/receptacle combo device in this situation.

How to replace a light switch with a switch/outlet combo

Scenario #2

A typical example of this situation is if you had the same scenario as above, but with a 3-wire circuit, such as in a kitchen split receptacle, and wanting to add some under-counter lighting for example.

Just as the receptacle that you replaced will have the tab on the hot side removed, here we have to remove the tab on the device as well. This will put the light on a different circuit as the receptacle, but again will give you the desired result of a usable receptacle, and a switched light fixture without a difficult wiring renovation.

How to replace a light switch with a switch/outlet combo

Keep in mind that this isn’t the best situation, as you now lose the required amount of circuits in the kitchen. However it is an example of how we can have the switch and receptacle operating independently from one another on different circuits.

Scenario #3

Here is a situation where your desired result is a receptacle controlled by the switch in the combination device.

Let’s say you have a task light for your shop, and it is cord connected and designed to be mounted over your work area and then just plugged in to an outlet. Instead of plugging the light in and out every time you want to control the light, this will allow you to keep it plugged in and use the switch for control.

How to replace a light switch with a switch/outlet combo

So there you have three examples of where a switch/receptacle combination device like this can come in handy.

Electrical Question: How Can I Replace a Garbage Disposal Switch with a Combination Switch?

  • I’m trying to replace a garbage disposal switch with a combination switch, and keep the bottom plug live at all times.
  • I’m not sure if it can be done with just the black, white, and ground wire.

This electrical question came from: Scott, a Homeowner from Milwaukee, Wisconsin.

Thanks for your electrical question Scott.

Wiring a Combo Switched Outlet

Application: Wiring for a Half Hot Switched Outlet.
Skill Level: Intermediate to Advanced – Best Installed by a Electrical Contractor or Certified Electrician.
Tools Required: Electricians Tools, including Pouch of Hand Tools, and a Voltage Tester.
Estimated Time: Depends on personal level experience, ability to work with tools and install electrical wiring.
Precaution: Identify the circuit power source at the panel, turn it OFF and Tag it with a Note before installing wiring or working or making connections.
Notice: Installing additional outlet wiring should be done through the local building authority, according to applicable local and national electrical codes, with a permit, and have required inspections.

Part 1. Wiring a Combo Switched Outlet or Half Hot Outlet

Applications for Combo Switch Outlets

  • Scott, a combo switch outlet will require the set of wires that are for the switched device, in this case the disposal, and the outlet will require a hot, neutral and ground wire.
    • If the combo switch outlet is being installed at the kitchen counter top area then the combo switch outlet will need to be a GFI combo switch outlet.

Part 2. Switch and Outlet Wiring

How to Convert a Switched Outlet

  • The switch I am replacing has two red wires plugged into the back of the receptacle, and two black wires plugged into the one below.
    • If I want to keep the same set up I can just connect the two red to the top brass screw and the two black to the bottom but must break the small brass tab between the screws not the plastic, correct?
  • If I don’t care to use the wall switch all I have to do is to cap off the red and connect one black to one brass screw and one to the other brass screw w/o touching the brass tab,correct?

Wiring Modification for a Non Switched Outlet

  • Insulating the Unused Wire
    • Yes, the red wire may be capped off and the outlet may remain hot all the time.

Do you know anything about electricity besides it can kill you? What electrical tools do you have and wiring knowledge?

I have put in some switches and light fixtures in my day, but I would not attempt this. My question was ill-phrased. I only wanted to know if it can be done safely, if at all. Thank you for your comments. One cannot be too careful.

Turn the circuit breaker off, that’s as safe as you’re going to be.

I hope you have some good DIY electrical skills and knowledge. If not–find someone who does!

Yes you can. Wiring diagram is last picture on the page.

My suggestion is to purchase what is called a grounded tap switch. Simply plug it into an existing electrical outlet that is already installed in the wall. There is no ‘electrical’ work necessary. When it is plugged in, the other side of the outlet is still free for something else. If you do need that side for something else, instead of the lamp, then simply unplug it.

If you are wanting access to a lamp to turn it on and off and it is not convenient to either reach up under the shade, or to crawl down to where the tap switch is plugged into the wall, an option is to purchase what is called a table top or credenza dimmer switch, which also turns on/off. Simply plug it in, like an extension cord; no ‘electrical’ work necessary.

Adding an electrical outlet next to an existing light switch is easy, as long as there is a neutral wire in the box.

Step 1: Turn the power supply off to the light switch at the main electrical panel.

Step 2: Remove the switch plate and unscrew the switch from the outlet box.

Step 3: Pull the switch out from the box. If there is a bundle of two white wires tied together behind the switch and two separate wires running to the switch, it will be easy to add an outlet.

Step 4: Use a voltage sensor to ensure that the power to the box is off by touching the sensor to each wire separately.

Step 5: Mark the two wires attached to the switch with electrical tape and disconnect the wires from the switch.

Step 6: Remove the existing outlet box and replace it with a double outlet box.

Step 7: Remove the wire nut connecting the two neutral wires in the back of the box and add a third white wire to the mix. Twist the wires together and cap them with a wire nut. Attach the loose end of the new wire to the silver screw on the new outlet.

Step 8: Attach two short black wires to the black wire that was originally on the gold screw of the switch. This should be the hot wire. Twist the three wires together and cap them with a wire nut. Attach the loose end of one new wire to the gold screw on the switch and attach the loose end of the second new wire to the gold screw on the outlet.

Step 9: Reattach the white wire that was originally on the switch to the silver screw on the switch.

Step 10: If there was a ground wire attached to the switch, attach two short green or bare wires to it and cap all three with a wire nut. Run the loose end of one ground wire to the green screw on the switch and run the loose end of the second wire to the green screw on the outlet.

Step 11: Once all the wires are attached, press the switch and outlet into the new box. Secure them with their mounting screws.

Step 12: Turn the power on and ensure everything is working properly before attaching the new cover plate.

How to wire a light switch and outlet in the same box?

In daily life, sometimes we will need to repair electrical appliances in the house by ourselves. Since there are many things involved with electrical appliances, they are not so complicated that it is necessary to hire an electrician. Wiring electrical outlets and light switches is a job you can do yourself if you learn and know how to install them. Wiring a single outlet or switch is probably quite simple, but putting together a socket and switch in the same box is a bit more complicated. In this article, we will learn together: How to wire a light switch and outlet in the same box?

Why do we need to wire a light switch and outlet in the same box?

Each house will have its own design and installation of electrical circuits. The installation of sockets and switches in the house is highly dependent on the electrical circuit and layout of the house. Sometimes we can separate the outlet and the switch, we can also install 2 sockets in one enclosure box or 2 switches in the same box. So when do we need to wire the socket and the switch together? We will wire them in one box in the following cases:

  • There’s only one power source in the room
  • Only one enclosure box can be installed
  • Wiring a light switch and outlet in one box will bring convenience when using the devices

This installation is not too difficult and we can do it ourselves. However, it is also necessary to have the basic knowledge to ensure that you install it safely and according to your intended use.

What is the combo of a light switch and outlet?

A combo of switch and outlet is that we install the same outlet and switch in one enclosure box. The switch can be used to control light bulbs or other items, while sockets are used to plug-in electricity. You can also use that switch to control the outlet.

For each different purpose, we will have different installation methods. Corresponding to each of these ways are different circuit diagrams. Therefore, in order to know how to install it properly for our purposes, we also need to understand the basic information about the installation methods. When installing electrical equipment, we need to pay attention to Line Hot and Line Neutral. We also need to know the basic difference between installing Switch and Outlet combo devices with Combo GFCI. There will be a break-away fin tab in combo Switch and Outlet, while the GFCI device way does not.

This break-way fin tab can be removed and then you can control the additional load.

How many ways to wire a light switch and outlet in one box? And what is the difference?

The ways to wire switch and outlet in the same box are divided based on their intended use and how they are installed. We have 2 ways as follows:

  • Wiring a light switch and outlet in the same box in the usual way

In this diagram, we use one power source: Switch is used to control the light bulb, ( or control some other devices). The socket is used for other devices. Sockets and switches share the same power source but are not affected by each other.

  • Wiring Combo Device where Switch & Outlet Controlled by Different Sources:

In this diagram, the purpose of the switch and outlet remains the same, but they are connected to separate power sources.

In addition, if the Switch is not used to control the light bulb, we can learn another way to install it, This is the wiring Combo Device where Switch & Outlet, in which the switch is used to control the Outlet.

How to wire a light switch and outlet in the same box?

#1. Wiring a light switch and outlet in the same box with a source

This is the simplest diagram of the combo switch and outlet installation methods. This is also a common method that we usually use.

In this way, Two devices use the same hot source. We don’t need to remove the break-away fin tab from the device.

Let’s start with the switch, Line Hot will be connected to the one line of the switch, The load side of the switch will be connected to the light bulb. For sockets, the neutral silver terminal of the outlet will be connected to Line Neutral, and then, do the proper earthing and grounding connections. The Line Neutral will also be connected to the light bulb, so we will have a wire nut.

Once installed, the switch controls the light source, and the socket outlet can be used for other loads and can be connected via plugs.

#2. Wiring Combo Device where Switch & Outlet Controlled by Different Sources

For this installation, you need to remove the break-away fin tab. If it still exists, the wiring will not be possible.

With this installation, the outlet will use one power source, and the switch controlling the bulb will be connected to another power source. 2 devices will be separate. Here we will use 2 power sources, we call these two powers: source 1 and source 2. Each source has a Hotwire and neutral wire.

After removing the break-away fin tab, connect the switch terminal to Line Hot of source 1, the switch load will be connected to the light bulb. The neutral line of source 1 is connected to the light bulb.

Regarding the socket, one terminal will be connected to Line Hot of source 2, the other terminal will be connected to Line neutral. And then measure the proper earthing and grounding connections

Some other ways to wire outlet and switch in the same box:

If you want to learn more, we also have a combo of many outlets, switches, or a combo of many sockets and switches. Here, we can learn another simple diagram. Instead of using a switch to control the light bulb, we can also use the switch to control other devices or even the socket. If the switch controls the outlet, the switch can cut off the power of the socket.

In this diagram, first, the break-away fin tab between two hot terminals will also be removed. One terminal of the switch is connected to the hot wire of the power supply. Connect The load side of the switch to a terminal of the socket. Then connect Line Neutral to the other terminal of the outlet.

The last step is doing the proper earthing and grounding connections.

A few notes on installation:

To ensure the safest when conducting wiring, note a few criteria below:

  • It is advisable to prepare an electric tester to ensure safety when placing it.
  • Choose a convenient installation location, easy to operate, not entangled, not obscured.
  • Choose a location where children rarely go or play, or use a protective box to shield the electrical outlet.
  • Do not place the power outlet in damp places such as toilets, washing machines, and sinks.
  • The power outlet should be replaced immediately if any damage or leakage occurs.

Conclusion

Wiring a light switch and outlet in the same box are not too complicated or difficult, we can completely install it at home if we understand the principles and have a basic understanding. Knowing how to install sockets, switches in general and wiring a combo of the light switch and outlets, in particular, will help a lot. Besides, there are also many other diagrams, if you are interested, you can learn more to know more useful knowledge.

Do you want to add a light fixture but don’t know where to start?
If you want to install a new light fixture but aren’t sure where to begin, then you need to understand how electrical circuits work.
This blog post will teach you how to wire a light fixture into an existing circuit.

Adding a light fixture and switch to an existing circuit

If you are adding a light fixture and switch, you will need to know what type of wiring is already present in the house. This information will help determine whether you need to run new wire from the breaker box to the light fixture location. In addition, if you are replacing a light fixture, you will need to determine how many fixtures are currently connected to the same circuit. This will allow you to determine where the new fixture needs to go.

Let’s discuss the method of Adding a light fixture and switch to an existing circuit in details.

Adding a light fixture and switch requires two wires to connect the light fixture to the electrical panel. One wire goes to the light fixture and the other wire connects to the switch. The switch is usually located near the light fixture.

Method to add a light fixture and switch to the existing circuit

Step 1: Turn off power to the circuit breaker box. Step 2: Remove the old light fixture from the ceiling.

severe electric shock

Step 3: Install new light fixture. Step 4: Connect wires to the new light fixture. step 5: Switch on the power supply.

Attachment of additional switch

Step 1: Remove the old switch from the wall socket. Step 2: Cut off the wire connected to the switch. Step 3: Strip the insulation from the end of the wire. Step 4: Twist the bare copper wire around the screw terminal of the new switch. Step 5: Screw the switch into place. Step 6: Connect the other end of the wire to the switch.

Can I spur a light from another light?

You can add a switch and light fixture to an existing circuit using two methods. First, you can simply replace the existing switch with a new one. This method works well if you only need to add a switch to a circuit. However, if you need to add a switch and light, you’ll have to replace the existing switch with one that includes a light. Second, you can add a switch and a light fixture to an existing switch. In this case, you’ll need to cut the wire coming from the breaker panel and splice it directly into the terminal on the switch. Then, you’ll need to attach a light fixture to the switch.

Can you add a light and switch from an outlet?

If you want to add a switch to an already wired circuit, you’ll first need to determine what type of switch you want to install. Most switches are designed to fit into a specific type of junction box, such as a duplex switch or single pole switch. Once you know what type of switch you’re looking for, you can go online and search for the proper part. To add a switch to an outlet, you’ll need to remove the old switch and replace it with a new one. To do this, turn off power to the outlet, disconnect the wires coming from the breaker panel, and remove the screws holding the old switch in place. Then, connect the wires from the switch to the appropriate terminals on the outlet. Finally, screw the new switch back onto the outlet.

How do you add a light switch in the middle of a circuit?

Fuses are used to protect electrical circuits from overloads caused by short circuits or excessive current flow. Fuse boxes are usually mounted near switches or outlets. A fuse protects a circuit from damage if the load exceeds the amperage rating of the fuse. Circuit breakers interrupt the flow of electricity to prevent damage to appliances and wiring. Circuit breakers are typically installed next to switches or receptacles. A fuse box contains fuses that are rated according to the type of circuit they protect. For instance, a 120VAC circuit requires fuses rated at 20 amps or greater. A typical household uses 15 amp fuses. You can’t wire one light bulb to another unless you have access to the junction box where the wires enter the wall. In other words, you can’t run two separate circuits into the same junction box.

How do you add a switch to an existing circuit?

If you’re adding a new light fixture to an existing circuit, you’ll need to turn off power to the circuit breaker. Then remove the old fixture and install the new one. Next, flip the breaker back on. What is the difference between a fuse and a circuit breaker?

How do you add a switch and light to an existing circuit?

You can connect two lights together using a junction box. It’s usually located near the electrical panel.

Can you wire one light to another?

Yes, you can add a lamp to an existing switch. But if you are connecting a lamp to a regular outlet, you won’t get enough power to run the lamp. So you will have to buy an adapter to convert the voltage. How do I install a ceiling fan?

Can I add a light fixture to an existing switch?

Yes, you can add a light and switch to any outlet. But if you are using a regular outlet, you will not get enough power to run a lamp. So you will need to buy an adapter to connect the lamp to the socket.

The full guide for single-pole and 3-way switches.

Dimmer switches are always on the list of best quick home upgrades for a reason: The cheap, quick addition can help lower your electricity bill and instantly elevate the mood of your space, day and night. Plus, they’re good for the environment. While we recommend hiring an electrician when possible, dimmer switches are one of the easier swaps you can do yourself if you’re handy. Just be sure to turn the electricity off at your main fuse box before proceeding with the instructions and tutorial brought to us by Whitney Jones below!

Materials:

  • Dimmer switch
  • Flathead screwdriver
  • Phillips head screwdriver
  • Voltmeter
  • Wire Stripper
  • Measuring Tape
  • Needle-Nose Pliers (optional)

Turn off your electricity before proceeding with the steps listed.

Remove the old switch

  1. Before touching the original light switch, turn off the power at your fuse box. Test the light switch afterward to make sure the electricity is off.
  2. Unscrew the switch plate and save it if you are reusing it. Most dimmers come with a plate to fit the new dimensions, but some are made to fit standard plates. Check your new dimmer package for dimensions to make sure it will fit.
  3. Open the dimmer switch and strip the rubber coating from the wires. Expose at least 1 – 2 inches of copper wire to ensure a tight seal with the wall wires.
  4. Remove the old switch from the wall, carefully unwrapping the wires from the rubber section. Test the wires with the voltmeter to triple-check voltage levels.

Installing a single-pole switch

Single pole switches are your standard light switches. They control the electricity to one light source. You have a single-pole switch if you can only turn on/off your lights using a singular switch. If you can turn your lights off using a different switch than the one you used to turn them on, skip down to the 3-way switch section.

Single pole switches will have 3 wires: a hot lead wire, a ground wire, and a traveler wire. Older homes may only have a hot lead and a ground wire. If you have less than three wires, stop and call an electrician. Older or historic homes can have different wiring and need special care to install.

Have an older home with a single-pole switch? Box dimensions have changed over time. If your dimmer switch is too large for the box space, use a measuring tape to gauge the difference. Take a box cutter to widen the space in the drywall and accommodate the new switch before installing.

Make sure the electricity is turned off at the main fuse box before proceeding!

  1. Connect the ground wire to the corresponding wire on your dimmer. The ground wire is typically green or copper and should be connected to the bottom, center wire on your dimmer.
  2. Use a plastic wire cap to secure the two wires after wrapping, protecting the connection and ensuring a tight seal. Needle-nose pliers can help wrap and secure the wire in tight spaces.
  3. Next, connect the red wire to the hot lead wire and cap them together. They are usually marked red on the wall, but can be black and otherwise taped or marked off.
  4. Connect the final black wire to the remaining traveler wire in your wall, typically marked with a white or black rubber finish.
  5. Finish with a wire cap.
  6. Most dimmers have a fourth wire for a second traveler connection. Use a wire cap to seal the final wire and prevent it from touching the other wires.

Installing a 3-way switch

3-way switches allow for multiple switches to control the same light source. These are more common in new builds to allow for transition in open-concept spaces, but can also be found in midcentury homes that brought open concept living to life.

3-way switches are also marked with four wires in the wall outlet: a ground wire, a hot lead wire, and two travelers to allow for a connection to another switch or outlet.

Make sure the electricity is turned off at the main fuse box before proceeding.

  1. First, connect the ground wire to the corresponding wire on your dimmer. The ground wire is typically green or copper and should be connected to the bottom, center wire on your dimmer.
  2. Use a plastic wire cap to secure the two wires after wrapping, protecting the connection and ensuring a tight seal.
  3. Next, connect the red wire to the hot lead wire and cap them together. They are usually marked red on the wall, but can be black and otherwise taped or marked off.
  4. Connect the two black (one wire may be red with a white stripe) wires to the traveler wires in your wall, typically marked with a white or black rubber finish.
  5. Finish with wire caps.

Make sure you turn the power off to the light switch at your consumer unit.

Unscrew the two retaining screws on the switch and pull away the switch.

Tip If it’s an old switch that has been painted around many times over the years a good idea is to score round it with a sharp knife. This stops you pulling away the paint work on the walls.

Check that there is no live with your voltage checker, having previously checked that the voltage checker is actually working.
(see my section on voltage checker).

You will see differing amounts or cable depending on what type of switch it is and how it has been wired.
You’ll need to replace like with like and replace the cables in the same configuration. Make a note of what goes where and mark them with tape before you unscrew the cables. When you screw the cable to the new switch make sure they are nice and tight and no bare wire are showing. Re-fix the switch to the back box and turn power back on.

NB Metal switches must be earthed, and usually come supplied with an earth lead. This should be connected to the back box with the other earth cables that form part of the wiring. If you’re replacing a plastic switch with a metal one and there is no earth to connect to call a qualified electrician.

A one way switch has a common (C) and Line out (L1) terminal.
The common is the main live coming in. The L1 is the switched live going out to the light.They will be marked so you can tell which is which.

A two way switch (for switching a light from two different locations like in a hallway) has a common (C) a L1 and an L2 terminal. L1 is off when L2 is on and vice versa depending on the switch position.

You can use a two way switch for one way switching. Just ignore the L2 terminal. Some switches will actually come two way as standard for use as both.

An Intermediate switch (UK light switch) is used for switching a light from 3 or more locations in conjunction with two way switches.
They have 4 terminals L1, L2, L3, L4.

NB In light switches you are actually switching the live part of your circuit only so all of the cables(except the earths) even if they are different colours are actually part of the live not neutral. This may confuse you as the colours may be red and black for older cables or brown and blue if they are the newly introduced (post april 2006). This has been done for convenience when your wiring was done. If done properly the cables should have been clearly marked with colour coded sleeving as live. (red or brown)

Any bare earth cables should have yellow and green earth sleeving.

Safety First

Always turn the power off at the breaker before starting any electrical project. Once you’ve turned your power off, remove the switch cover and use a current detector to make sure there’s no power going to any of the wires in the electrical box. If there’s no power, you’re ready to move on to the first step.

Detach the Wires

Three wires will be attached to your switch: a hot (black) wire, a neutral (white) wire and a ground (copper) wire. The black and white wires are attached using brass screws (Image 1); when the power is on, these will both be “hot.” The copper wire is attached using a green screw; if you have an older home, you may not have a copper wire. Detach the three wires using a screwdriver and discard your old switch (Image 2).

Wire the New Switch

Each wire should have a half inch of wire exposed and bent into a U shape that will fit snugly around the screws on the switch. Your electrician’s pliers have a nifty feature made specifically for this purpose. On the edge of the pliers, you’ll find a small hole. Insert the wire into the hole and bend it around the lip of the pliers (Image 1). This should create the perfect U shape (Image 2).

Wrap your black wire clockwise around one of the brass screws. By wrapping clockwise (the same direction the screw turns), you ensure the wire’s connection will tighten when the screw is tightened. Repeat the process with the white wire, wrapping it clockwise around the other brass screw and tightening it with a screwdriver (Image 3). Finally, wrap your copper ground wire clockwise around the green grounding screw and tighten (Image 4). Your switch is now wired.

Wiring

You can wire a three-way switch circuit several ways, but all of them require special cables and switches. Here’s the simplest method.

I’ve wired switched plugs and three-way switches many times. But for a current project, I’d like to combine the two so that I can control an outlet with two switches. What’s the simplest way to do this?

Roe A. Osborn, Woodbury, CT

Clifford A. Popejoy, a licensed electrical contractor in Sacramento, California, replies: You can wire a three-way switch circuit several ways, but all of them require special cables and switches. The cable contains three current-carrying wires (rather than two) and a grounding wire. This three-wire cable is run between the two switches. The switches, called single pole, double throw (SPDT), are like an either/or switch: Power can be directed to or from the switches on either one wire or the other.

The three-wire cable is like standard nonmetallic sheathed (NM-B) cable, except there’s an extra hot. So in total, the cable has two hot wires, a neutral, and a ground. The two hot wires are called travelers; only one traveler carries current at a time.

The simplest three-way-switch configuration (see drawing) is to bring power to one switch, to run three current-carrying conductors between the first and second switches, and to feed power from the second switch to the load. This setup is just like a three-way switched light, except the black wire from the common terminal of the second switch and the accompanying neutral wire run to the receptacle outlet.

Although what is described and illustrated here is the simplest method of setting up a three-way circuit, you should bone up on the alternatives. If you’re troubleshooting, you could run into many different switch setups.

Today we’re bringing you a video from our workshop on wiring half-switched outlets. A half-switched outlet is an outlet where either the top or bottom half of the outlet is controlled by a switch, while the other half is always on. This outlet configuration is common in homes built in the 1980s, when this method of wiring reached peak popularity. This video explains one wiring approach for creating a half-switched outlet to help you either diagnose or create this configuration in the future.

In this example, the power comes from the breaker panel, then to the switch box, and then on to the outlet. After the video and a few pictures, I explain an alternative method that can be used to achieve a half switched outlet when power comes to the outlet first.

Wiring Diagram Walk Through

If the video moved too quickly, these pictures should make the wiring setup clear.

Alternate Wiring Method

In the approach in the video, power enters first at the switch. If power enters first at the outlet, it is possible to achieve a half-switched outlet by branching a switch wire. This is achieved by running two-wire cable from the outlet box to the switch box. Power leaves the outlet box on the white wire (which should be wrapped with black or red electrical tape to indicate that it is being used to carry “hot” to the switch”), then in the switch box the black and white wires are connected to the switch, effectively making the black wire “switched hot”, which runs back in the same cable to the outlet. Using some pigtails, you can attach both hot and switched hot to the top and bottom of the outlet.

Dave Rongey has a decent set of wiring diagrams for both methods of half-switched wiring. (There are a number of ads on this page… but I did think Dave’s drawings were a very good look at both wiring methods.) Note that recent changes in the National Electrical Code require a neutral wire be present in all switch boxes, which means the alternate method (where power enters into the outlet rather than the switch) is no longer acceptable, unless three-wire cable is run from the outlet to the switch, which provides no cost savings, and so isn’t a great solution.

Most modern bathrooms need enough outlets for appliances such as hair dryers, trimmers, electric brushes… Besides, you need to write down items such as Jacuzzi, heater, ventilation fan. , even the washing machine.

Jacuzzi and shower sockets can be installed behind the wall as these don’t need to be plugged in and pulled out as often. Next to the bathroom mirror (usually above the sink), you should have two sockets for small, frequently used appliances such as hair dryers, trimmers, electric brushes…

Rules to arrange switches, electrical sockets in the bathroom

If you intend to put the washing machine in the bathroom, create a separate space and arrange more sockets. Note, the socket for the washing machine should be located 50-60cm away from the faucet.

  1. The underground wires to the sockets and switches must originate from the horizontal trunk and the line should be arranged vertically with the electrical panel, switch, or socket.
  2. The power cord must be at least 10cm away from windows and doors.
  3. The main light switch should be located near the door at a height of 70-90cm.
  4. Light switches in the storage room should be located on the corridor wall.
  5. Switches for bedrooms, dining rooms, and kitchens should be located inside each room.
  6. Sockets in the rooms should be located 30cm from the floor, switches 90cm from the floor.

Finally, sockets and switches in bathrooms must meet standards of durability, insulation (protection class IP44) and must be properly grounded.

Two power switches wiring schematic diagram for fan link

The isolation of lights and fans by adding a two-button switch is ideal to connect fatigue fans in the kitchen or bathroom. The lamp is turned on one key and the second is for ventilation separately. This ventilator attachment is most widely found in homes because it only causes the ventilator to be enabled if appropriate.

Partial selection is adequate for general-purpose PCBs by adding a further jumper to the jumper. A set of 4 controls that are not sold here can also be seen. The drawback is the somewhat tougher nature and heat radiation.

Two power switches wiring schematic diagram for fan link

It’s not hard to connect a toilet or a bathroom fan, so you can start attaching it to yourself safe after you buy the fan. Only make sure you switch off the necessary circuit breaker in the electric panel and start operating only after checking that the power cable has no voltage.

If connections are good, please replace the fan. Check the relay if the sensor is in good condition and the fan is running. Unplug the relay and check the connectors for power off. Both relays must be powered by one terminal.

Otherwise, there may be a malfunction with the wiring from the fuse to the relay under the back of the fuse box. It is possible that the pin is ejected or the wire is burnt. If there is electricity, replace the relay and try again. One of the relays may have caught fire. If the fan still does not work, replace both relays.

The choice of configuration depends on the type of space and the fan model you have selected to attach the fan to an apartment or private residence. Remember, any scheme includes connections in the ground-to-the-ground 3-wire wires, but if you are fitted with the old two-wire conductors, everything is connected in the same way – just wires.

Substitute the burnt relay while this works. It’s rarely a computer problem, but a computer problem should not be ruled out. A power-resistive potentiometer can be used with the simplest controller. That’s the resistance paradox. We have picked a resistance of 100 Ohm with a loss power of 4-5 W. You are surely curious why so many watts if the previous resistor has a power loss of two watts.

For example, 4 W of all resistance paths for a potentiometer is set to half, so the capacity loss is half that of 2 W for 50 ohms.

*** Refer to more video “Separate Switches for Bath Fan and Light from Single Switch” by Sparky Channel at this:

The simplest and most common light switch is actually referred to by hardware dealers and electricians as a “single-pole light switch.” With a single-pole light switch, flipping the toggle or paddle up completes the circuit, turning lights or appliances on, and flipping it down breaks the circuit, turning lights or receptacles off.

A single-pole switch has two brass terminal screws on the side that receive the black (“hot”) wires of the circuit. One black wire comes from the power source and the other goes to the light(s).

When you turn the switch off, it interrupts the electricity that flows through the black wire from the power source to the fixture. For this reason, the two main terminals are connected to black wires. The circuit’s bare ground wire—if there is one— is connected to the green grounding screw on the switch.

The wiring diagrams on this page can help you plan the proper way to wire for a light switch. Always turn off the power to the circuit before working on wiring. See How to Turn Off Your Home’s Electricity.

Again…the circuit’s white wires bypass the switch UNLESS…a white wire has been converted to do the job of a black wire. Many homes are wired with 3-wire non-metallic cable (such as the brand Romex®) that consists of one black wire, one white wire, and one bare or green grounding wire.

When wiring switches, this type of cable may be used as a switch leg—where you need two black wires to go from the switch to black wires located at the light or at an intermediate electrical box.

As shown in the diagrams below, you can paint a couple of inches of the end of the white wire black—or wrap it with black electrical tape—to indicate that it is being used as a black wire. Electrical codes can vary on this practice. How to replace a light switch with a switch/outlet comboStandard Single-pole Light Switch Circuit Diagram

Welcome to mariaelectricals.com. In this article, you will learn how to wire a light switch. Both a single pole, two-way, and dimmer switches.

Though it is the work of a licensed electrician to wire a house and electrical box, you as a homeowner can still do some simple installations such as light switch wiring.

Wiring a light switch is one of the easiest things in electrical installation, especially a single-pole. But for non-electrical workers, it always seems to be hard.

Below is a step-by-step guide to wall switch installations in your domestic and residential homes.

How to replace a light switch with a switch/outlet combo

Required tools and materials.

  • Screwdriver
  • Needle nose plier
  • Wire stripper
  • Utility knife

Materials

  • Light switch
  • 14/2 electrical wire
  • Wire nuts.

Wire colours and where to use them.

  • Black copper wire: This is a load or hot wire.
  • White wire: Neutral
  • Red wire: Used in 3 or 4-way switch wiring to connect switches together to control the lights.
  • Green wire or bare copper: Earth or ground wire.

Note: Before you work on the electrical system, always turn OFF the control switch or the circuit breaker that controls the branch circuit, and also wear your glove.

How to wire a light switch in 3 steps

To wire a single-pole light switch, just follow the underlisted steps.

Step 1: Power off the branch circuit

How to replace a light switch with a switch/outlet combo

Before you work on the electrical field, switch off the circuit breaker that controls the circuit.

This is to rule out the chances of electric shock during the installation.

You should also put on your personal protective equipment (PPE) such as your safety glove, boot, and equally work with insulated tools.

Step 2: Connect the wires

How to replace a light switch with a switch/outlet combo How to replace a light switch with a switch/outlet combo

The 14 gauge two wires come with 3 wires, one black hot wire, a neutral white wire and a copper ground wire.

While the switch also comes with three terminals, one earth, and two hot.

  • Remove the wire coat with your utility knife and wire stripper
  • Connect the two neutral white wires together. (The neutral from the power source and the one going to the lamp holder).
  • Join the two earth wires and also connect them to the green earth terminal of the switch
  • Connect the black hot wire from the power source to one of the brown terminals of the switch.
  • Also, connect the black wire from your lamp holder to the second brown terminal to complete the wiring.

Step 3: Attach the switch on the wall

Mount the switch on the metal box and tighten it with screws, and make sure the wires in the box are not trapped.

How to wire a 2-way circuit

How to replace a light switch with a switch/outlet combo

A 2-way light switch, also called staircase switches, allows you to control a light bulb from two different locations.

It is useful in staircase lighting and hallways as you can light on the bulb before climbing upstairs and also OFF it when you climb up.

The two-way switches have three screw terminals: COM, L1, and L2.

Intermediate Switch Wiring

How to replace a light switch with a switch/outlet combo

Intermediate wiring is like two ways but requires three switches. They are useful in staircases or big buildings where you want to control one light from three locations.

How to install a dimmer switch

Dimmer installation is quite easy, it is like single-pole wiring. Dimmers usually come with three short wires, two blacks, and one earth wire.

Before any installation, check the power rating of the dimmer you buy. Most of them can handle up to 600 watts.

Check the wattage of your bulbs and make sure you did not overload the dimmer.

Note: Dimmer switches don’t work on most fluorescent and LED bulbs. These lights require low-voltage dimmers.

Here are the steps to follow.

  • Turn OFF the power from your electrical panel
  • Unscrew the switch plate and also check the circuit with voltage tester to make sure it is dead.
  • Lose the switch from the electrical box and pull it out.
  • Disconnect the old wires from the switch and connect the dimmer.
  • Use the connectors that come with the fixtures to connect the wires, respectively.

Frequently Asked Questions

Does it matter which wire goes where on a smart light switch?

No, it does not matter provided it is a single-pole switch with two terminals. The light switch doesn’t have neutral terminals, it’s all hot wires from the supply and then to the bulb.

What is the meaning of L1 and L2 on a light switch?

L1 and L2 means line 1 and line 2, while COM is common.

Hardwiring LED Under Cabinet Lighting: A How-To Guide

Posted by Chris Johnson on Sep 16th 2015

When you spend a lot of time in your kitchen, ample LED under cabinet lighting can make your culinary adventures more satisfying and less frustrating. These types of fixtures and undercounter lights provide focused illumination for tasks, letting you achieve the right amount of brightness for everything from chopping vegetables to filling containers for meal prep. While you can put adhesive-backed fixtures in these spaces, properly installed kitchen under cabinet lighting is the way to go for consistent results.

Installing LED Under Cabinet Lighting

Hardwiring LED under cabinet lighting to a wall switch may be the most convenient way to install them in your kitchen. The hardwiring arrangement lets you turn your lights on and off and even dim them without having wires and plugs in your cooking space. When it comes to installation, however, hardwiring typically is the most involved option for expanding kitchen lighting. Read on for step-by-step instructions if you’re searching for advice on how to hardwire under cabinet lights.

1. Prepare for kitchen under cabinet lighting installation.

The first step required to install undercounter lights or LED under cabinet lighting is picking out the fixtures. Before you choose, however, measure areas where the lights will go to be sure your kitchen under cabinet lighting fits in your available space.

2. Consult with an electrical contractor before you start.

Before you begin, it may be helpful to seek advice from a professional electrical contractor. They can help answer any questions you have regarding electrical details. Also, local industry professionals can make certain you’re satisfying all the appropriate electrical code requirements relative to your city, county and state.

2. Plan for wiring for LED under cabinet lighting.

Knowing where you want everything to go before you get started simplifies the process of installing kitchen under cabinet lighting . For example, where do you want to place the light switch? Do you need it close to your cabinets or alongside the rest of your kitchen lighting controls? Determining the answers to questions like this also helps you know how much wiring you need since installation requires running electrical wire within the wall, looping it from one fixture to the next.

You may find it helpful to sketch out the kitchen area including cabinets and dimensions. A rudimentary sketch can help you adequately plan how many lights and how much wire are needed, and help you visualize how it will look once installed. Additionally, making changes to a drawing is much easier (and cheaper) than making changes during installation. [SF1]

3. Position your LED under cabinet lighting.

For even lighting throughout the kitchen space, linear lights that run along the length of your cabinets are an excellent choice. Task lighting that runs along your counters should sit close to the front of the upper cabinet to provide lighting to the edge of the countertop. Corner cabinet lighting should be balanced to cover the countertop area sufficiently without causing shadows.

4. Gather tools and mounting hardware.

Most LED under cabinet fixtures come with a pack of appropriate hardware to use for installation. This includes screws that don’t penetrate the bottom shelves of your cabinets plus the right-size cable bushing and wire connectors for proper installation. You may also need the following tools:

• Electrical wire and pressure connectors

• Drill with keyhole saw

5. Disconnect the power.

Locate the correct breaker and turn off the power supply to the switch outlet where you’re going to hardwire the lights. Ignoring this step can be dangerous and result in serious injury or death.

6. Attach the lights.

Position the lights according to how you laid them out earlier. Take apart the under-counter lights and screw them where you want them to go. To make this easier, it helps to use a pencil to mark the bottom of the cabinets. Some undercabinet lights come with paper templates or a removable mounting plate to help make these screw marks.

7. Cut the wall.

Depending on where your backsplash is located, you may have to peel it away from where you’re installing kitchen under cabinet lighting. Cut a channel behind the backsplash using your drywall saw. The channel should stretch from under the switch box to the right near the farthest light. Finally, use the drill to bore a hole through the studs so you can run the wire.

8. Run the wire.

Next, use the drill again to create a hole for each individual light’s wire. A wire fish may be helpful here for running the wires down the wall from one fixture through the channel and onto the next fixture.

9. Run the cord.

Beginning with the farthest fixture from the switch, run electrical wire from one fixture to another. Leave about 1 foot of cord at each opening.

At the farthest fixture, you should have a foot of cord hanging out of the end, and the fixture next to it should have two cords hanging out (one entering and one exiting).

Do this for every light until you get to the one closest to the switch — this light needs one length of wire coming from the switch box and one leaving the light on its other side.

10. Connect the lights.

Isolate the electrical wire inside each LED light , separate the wires if necessary and remove about 3/4 of an inch of the insulation from them.

At the closest fixture to the switch, attach the wires with the wire nuts.

Next, connect the black fixture wire with an electrical wire in the wall with the plug on the end and a wire heading to the next fixture. Do the same for the white fixture wire.

11. Wire the switch.

At the switch outlet, make sure the electricity is off, then remove the receptacle.

Bind the white wire and the connecting strand of cord together with a wire nut.

Screw the black wire on the outlet onto the switch’s bottom terminal, then screw the black wire that goes out to the lights into the switch’s top terminal.

12. Cover your work.

Cover the switch’s terminals by wrapping them with electrical tape. Then, screw the switch back into the box and attach the switch cover.

13. Test the lights.

Restore power to your lights and flip the switch to see if they work.

14. Patch things up.

Now that you’ve successfully installed your LED under cabinet lighting, you can redo the drywall you had to slice away for the wire channel. Reattach the backsplash after you finish, and enjoy your new kitchen under cabinet lighting!

Light switches, once a simple decision, are now a home improvement category boasting a number of designs and functions. With different switch styles, wiring needs, and programmable capabilities, the wide variety of light switches and dimmers can be tricky to navigate. However, the basic function always remains the same: Turn a switch on and it completes the circuit, letting electricity flow through it. Turning it off breaks the circuit, as the switch creates a gap that stops the flow. After choosing the perfect chandelier, pendant, or recessed lighting for your home makeover, make sure you pick the right electrical switch for your needs. Take a look at our guide to switches and dimmers to pick the right lighting option for your room.

Types of Switches and Dimmers

Be sure to select a switch that’s compatible with the circuit where you want to install it and your lighting needs. Here are the basic types of switches and dimmers.

Essential Light Switches

The most common household switch, a single-pole, has two terminals and simply turns power on or off. A three-way switch has three terminals; a four-way has four. These control a light from two or three switch locations, such as at the top and bottom of a stairwell, at either end of a hallway, or in a large room with multiple entrances.

A dimmer switch controls a light’s intensity. You can usually replace any single-pole switch with a dimmer. However, for a fan or fluorescent light, you should buy a special switch rated to control those devices.

Special Light Switches

In addition to the familiar toggle and rotary switches, specialty switches can do everything from turning on when you walk into a room to varying the speed of whole-house fans. Other special-duty switches can be time-programmed or let you know whether a remote light is on or off. Decorative switches include styles that rock, turn, or slide rather than toggle.

Single-Pole Switch

Single-pole switches have two brass terminal screws and a toggle labeled ON and OFF. Most also have a grounding screw that connects to the circuit’s ground wire. This type of light switch controls one light fixture (or electrical outlet) from a single location. When installing, always connect two hot wires to it, not two neutrals. One terminal connects to the incoming power-source wire, while the other is used for the outgoing hot wire to the fixture. This light switch is good for small rooms that don’t have many light sources.

Three-Way Switch

Three-way switches have three terminals (in addition to a ground terminal) and can control one fixture from two locations. Because it’s always paired with a second switch, its toggle is not marked on or off. Often found in stairwells or long hallways, three-way switches mean you don’t have to walk in the dark to find a switch.

How to replace a light switch with a switch/outlet combo

Live in an older home with two-prong outlets? You’re probably running out of outlet space for electronics with three-prong plugs.

Here’s how an electrician can fix this problem for you!

The Three-Prong Access vs. Affordable Solution Conundrum

There are abundant reasons homeowners shy away from rewiring their homes. Although this option offers the safest solution for three-prong outlet access, it may not be the most feasible one. Rewiring a home is expensive and time-consuming. There are other ways your electrician can upgrade your outlets without rewiring. For example, ungrounded three-prong outlets can be installed; however, there are risks involved with using non-grounded three-prong outlets.

Two-prong outlets have no ground wire, without which the risk of electrocution and appliance damage is substantial. Simply adding an outlet with an additional prong will give you added appliance access, but it will not give you the safety that grounding provides.

Should You Change a Two-Prong to a Three-Prong Outlet with No Ground Wire?

Converting a two-prong outlet to an ungrounded three-prong GFCI protects you from electric shock. However, a ungrounded three-prong GFCI will not provide the necessary ground protection that prevents sensitive electronics from being fried during voltage fluctuations.

Think using a surge protector strip will fix the problem? Unfortunately, those devices are only as good as the outlet they’re connected to. No grounded outlet = no surge protection. Mr. Electric does not recommend installing ungrounded three-prong outlets, but we understand that it can provide a temporary solution for some homeowners.

How Electricians Replace a Two-Prong Outlet with a Three-Prong GFCI

Here’s how professional electricians replace two-prong outlets with three-prong GFCI plugs without running a new ground wire to the electrical panel:

  1. The power to the outlet being replaced is turned off at the service panel. This will be confirmed at the outlet with a multimeter.
  2. The cover plate screw and cover will be removed, along with the two screws holding the old receptacle into the box.
  3. The old outlet will be pulled out, being careful not to crack the old wiring. It will be gently extended to gain access to the wires.
  4. The old outlet will be disconnected.
  5. Some old boxes are tight, so the new GFCI must be test-fitted by gently pushing the wires back and ensuring the new box will fit. If it doesn’t fit, a new, larger electrical box will be used.
  6. If the wires aren’t long enough, a 4-6″ extension (“pigtails”) will be added using the appropriate wire for the circuit amperage: 15 amp = 14 gauge; 20 amp = 12 gauge. (DIYers with significant electrical experience attempting this project would have to pick up one white wire and one black wire from a local hardware store, along with the appropriate wire nuts to add the extensions.)
  7. If the wires are long enough, the electrician will look at the terminals on the GFCI and identify the “Line” terminals. These are the only ones that will be used. The wires will be connected:
    • Black wire to the brass “Line” terminal screw.
    • White wire to the silver “Line” terminal screw.
  8. The wires will be gently folded back in the box, pressing in the new outlet.
  9. The box will be screwed-in to fasten.
  10. The outlet will be tested by pushing RESET to turn it on, and then TEST to shut it off. The cover plate will be re-attached and a NO GROUND sticker will be applied.

How to Ground a Two-Prong Outlet

To ensure safety, eventually you’ll want to have grounded outlets. If your home is grounded but some of your outlets are not, bringing in a licensed electrician is the best way to ensure the modifications are completed safely and correctly.

Grounding an outlet requires attaching a wire and running it all the way from your outlet to the grounding screw at the back of your electrical box, which is often a long, complicated endeavor, and exceedingly painful for the inexperienced – sometimes “shockingly” so.

A common question we get is, “What is the relay for and how do I wire it up?” So here is an overview of what a relay is, why you likely need it, and how to wire it up.

What is a Relay?

A relay is an electrical switch. It allows a low current “switch” circuit to control the electricity flow of a high-current circuit load, like your LED Light bar for example.

Why Do I Need A Relay?

When you create a circuit (a loop of electricity from the battery to your LED Light bar), if you just put a switch between the battery and the light, it will have to be rated for the full current (amp draw) of the light. Our lowest amp draw LED light pod has an amp draw of about 1.4 amps. Many switches would be able to handle that. but if you are using, say our 50″ LED Light bar, that has an amp draw of about 17.2 amps, which may be too much for that little switch to handle. As a result, you could end up overheating the switch, melting the wires, and reducing the current that is getting to your lights, making them not as bright.

Check our our selection of LED Light Bars

How to replace a light switch with a switch/outlet combo

Another reason you may want a relay is for the creative ways you can use electrical currents from things other than a physical switch. Let’s say you want have your LED Light Bar come on with your high beams, or reverse lights, for example. Read more about that below.

How to Wire your LED Light Bar Using a Relay

The relay will have 4 prongs on it, marked 30, 87, 85 and 86. Kind of cryptic isn’t it. Well if you are just going to use our wiring harness, and switch, you don’t need to know what any of this is, because it comes all pre-wired and plugged in together.

How to replace a light switch with a switch/outlet combo

But if you want to use some sort of electrical current to activate your LED lightbar, like make them come on when you turn your high beams on, or your reverse lights on (if you are adding LED backup lights), then you’ll need to do a bit of rework.

First, let’s explain the what these 30, 85, 86, 87 numbers are. Let’s start with a picture:

How to replace a light switch with a switch/outlet combo

30 and 87 create the switch to your LED lights. By default this switch is open, so current cannot get from the battery to your lights.

30 – is your power source for your LED lightbar. It connects to the positive (+) side of your battery or to a switched power source that only gets power when your ignition is on.
87 – goes to the positive side of your LED lights.

85 and 86 use electrical current to create a magnetic force, which then closes the 30 to 87 switch and allows the electricity to flow to your lights. Without this current, no magnetic force is created, so the 30 to 87 switch stays open, and your lights stay off.

85 – connect to the power source that you want controlling the switch. For example you could splice a wire off your high beam wire or off your backup light wire
86 – connect to a ground.

(Note: 85 and 86 can be reversed, but our harnesses have them setup this way).

“What if I don’t always want my LED Light to come on with my high beams or backup lights?”

Good question! So you’d want another switch on your dash that you turn off and on. When it is off, and you put your high beams on, your LED light will still be off and vice versa. In this case, you need to wire the dash switch in between the trigger current, i.e. the line you spliced off your high beam wire or your backup light wire.

With our wiring harness, all you need to do is cut the wire coming from the switch to the 30 prong on the relay, and wire it to your high beam lead or your backup light wire. That way, when you do have your high beams on, the current from that goes to the dash switch first, and if that is off, the electricity can’t get to the 85/86 circuit to create the magnetic force to close the 30/87 circuit, which turns on your LED lights.
