What do I do with the red wire?
Red: Hot Wire You will usually only see a red wire when an outlet is a 240-volt outlet or when a wall switch controls the outlet. In this case, when the switch is "on," the red wire will supply power to the outlet instead of the black wire. Like black electrical wires, red wires are also hot or live wires.14-Feb-2022

These are called terminal screws. You should also see a green wire, called a ground wire, which attaches to a screw on the lower-left side of the light switch.
Why do you have to ensure that the wires are reattached to the replacement switch?
Because electrical wires experience stress over time and can weaken with usage, you must ensure that when the wires are reattached to the replacement switch, any portion of the wire that makes contact with the screws is undamaged.
How long does it take to wire a light switch?
Once you’ve learned the procedure, you should find that it takes no more than 10 minutes to wire a light switch.
How to connect black wire to a screw?
Start with the black wires, connecting them to the terminal screws on the right side. Their hooks should be oriented in a clockwise position. Proceed to attach the green wire, the ground, to the screw on the left. You may find that needle-nose pliers, though not essential, can help keep the wires in place as you tighten each screw.
What is a Light Switch?
The light switch is an electrical component used to control and operate the lights, bulbs, the equipment connected with it, and any electrical outlet connected with it. Switches are of different types and are used for different purposes. Usually, the switches only do ON or OFF the device that is connected with it.
How a Light Switch Works?
When the current is passed through the switch to the load, that is, bulbs, ceiling lights, etc. It makes the light turn ON. But when you push the button to OFF the light, it entirely breaks the circuit, and the passing of electricity is interrupted. What happens is there is always a space between the hot wire and the switch.

It is essential to wire a light switch correctly. Wiring it incorrectly often leads to a fire in the switchboard that causes significant accidents. It may also give the electric shock. So, it is best always to consult the electrician to wire your light and switch.
What wire goes straight to the light?
The white or neutral wire bypasses the switch and goes straight to your lights. This wire is needed to complete the circuit. The ground wire (sometimes in a green jacket) should be connected to your switch and to your lights. When you are finished, it is a good idea to wrap the switch with electrical tape to cover the connections.
Why is it important to read the directions on a light switch?
It is important to also read the directions that come with your particular light switch because there may be something different about the one you purchased or a change in technology that would require a different light switch installation. Before you do anything, you will need to cut the power to the light switch.
What is a three way switch?
Three-way switches will have traveler screws or connection points. These will be wired from one switch to the other so that the lights will turn on or off regardless as to which switch you use. The white wires in this situation are just connected together and never touch the switches.
How many wires are needed to wire a switch?
The black wire is going to be connected to the black screw on the switch. The main wire that will go from one switch to the other should have 4 wires total (black, white, ground and red). Review the diagram below for basic three-way wiring instructions.
What is a 3 way light switch?
A three-way light switch is one where you have two switches that have the ability to control the same light or set of lights. Therefore, the 2 switches + the light = 3 way. There will be an additional wire needed (often red) to connect the switches together to a dedicated screw or input on the switch that is specifically marked for this purpose.
How to strip insulation from wire?
It will either be 12 or 14 gauge wire. Then, use your wire strippers and strip away about 5/8 of an inch of the insulation from the wire. The wire strippers should have a spot marked for each gauge wire. Next, bend the wire into a pig tail loop so that you can easily attach ...
Do you need to cut the power to a light switch?
Before you do anything, you will need to cut the power to the light switch. If you do not know which breaker feeds your switch, then just turn on the light and test each breaker until you find the one that turns off your lights.
Step 1
Step 2
- Once you are positive that power has been cut to this particular switch, unscrew the switch plate (most are secured with two small flathead screws), then unscrew the old switch from the wall (here, flat-head and Phillips-head screws are equally common). Carefully pull out the old switch but leave the wiresconnected for now.
Step 3
- Observe the layout of the wires. You should see two black wires, each connecting to a different screw on the right side of the switch. These are called terminal screws. You should also see a green wire, called a ground wire, which attaches to a screw on the lower-left side of the light switch.
Step 4
- Loosen the screws holding the terminal wires in place. Once done, free the terminal wires, using pliers if necessary to undo a tight coil. Likewise, free the ground wire. At this point, you should be able to remove the switch from the wall; if it makes your job any easier, go ahead and bend the dangling wires out of the way.
Step 5
- Examine the ends of the wires for evidence of fraying. Clip off any degraded portions with a multitoolor wire cutters. Remember to leave about a half-inch of wire exposed on each length. Because electrical wires experience stress over time and can weaken with usage, you must ensure that when the wires are reattached to the replacement switch, any portion of the wire tha…
Step 6
- Use a multitool or pliersto bend each exposed wire into a round hook. Try to round those hooks tightly enough so they fit snugly around the curve of the screws on the replacement light switch.
Step 7
- Now attach the hooked ends of the wires to the new switch. Start with the black wires, connecting them to the terminal screws on the right side. Their hooks should be oriented in a clockwise position. Proceed to attach the green wire, the ground, to the screw on the left. You may find that needle-nose pliers, though not essential, can help keep the wires in place as you tighten each scr…
Step 8
- Protect the switch from fires by wrapping electrical tape around the body and the terminal screws. Finally, screw the switch back into the wall, replace the switch plate, and turn the circuit breaker back on. That’s it—you’re done. Now let the light shine on!
