To connect the power from the light switch, connect the hot wire coming from the light fixture to the common screw of the 2nd switch. Tie the ground and white wires together. And again, connect the remaining black and red wires to the traveler screws.
And this site to explore more methods for 3-way switching. Now we go to the 4-way switch. This method is employed for large rooms and long hallways; basically any room that is too large for just one or two switches. Who wants to walk a long way just to turn off a light switch?
So use 4-way switch wiring to have 3 switches for your lights. When installing a 4-way switch , you need to have an existing 3-way switch pair. Essentially, you are inserting another switch in between the two 3-way switches.
Feb 21, Powering a double switch controlling two separate light fixtures from a single power source isn't a casual DIY project, unless you're confident of. A double-switch allows you to operate two lights or appliances from the The only one that will light up is the feed wire, because it is currently hot with electricity.
To do this, you would have to cut the wire in between the two switches to make room for your third switch. Then, you would have to connect one black wire and one red wire from the first switch onto your third switch; screw the black wire on the top terminal and the red wire on the other side, also on the top terminal. Now, the black wire and red wire from the second switch will go on the bottom terminals, but the black wire will go on the same side as the first black wire, and same goes for the red one.
To add more switches to your circuit, just do the same method! Cut in between and connect your nth switch. I hope you learned a lot from this article. After all, wiring light switches is one of the basic skills a DIY-er or aspiring handyman needs to have.

This blog is the fruit of my extensive experiences as an interior designer and home improvement enthusiast. More so, I'm here to share with you a lot of great ideas on what YOU can do to make your home into a masterpiece: Before you start working, put the grounding strap on and connect the other end to the bare metal in the box.
Then, the circuit tester to make sure the current is actually turned off. Press the contacts to each wire and each space between each wire. If current is not present, you can continue. There are hot wires, neutral wires, and a grounding wire in nearly all electrical wiring. The hot wire is usually red, but can also be black. A wire that is bare, green, or yellow or green with a yellow stripe is the grounding wire, and the white wire is the neutral wire.
In a double light switch setup, you will have multiple wires including one set each light fixture and one set that goes to the breaker box. Place a strip of electrical tape around the hot wires so that you can identify them easily later.
Check the connections of the wires. Most issues are due to a bad or loose connection. Partially unscrew the feed wire and both neutral wires. Make sure they are hooked tightly around the screw before tightening them back down. Use a pair of needle-nose pliers to clamp the ends of the wire around the screw.
Make sure there is enough wire exposed to make a connection with the terminal. If the end of the wire is frayed or nicked up, cut it off, strip another inch of insulation off, and use this end. You have multiple hot feed wires. This is common with some older boxes, when you have two single switches hooked up instead of one double switch. A hot wire red or black comes out of the wall and into one switch, then out of that switch and into the other one.
It may, in some cases, even return to the wall from the second switch. Don't let this discourage you -- simply attach the hot wire on the new fixture exactly how you found it on the old wire. This is why there are often two terminal screws on the feed side. Some electricians will cut the wire covering in the middle, loop the wire in the terminal, and allow the rest of the wire to continue into the wall. You should do the same thing if you see this is the case in your old switch. Make sure that you have the feed wire connected to the right side of the switch.
If checking your connections still doesn't work, you should make sure that the feed wire is in the correct side of the switch. If your switch does not have it labeled, it is the side with the metal tab, or "fin. If there are two black terminals on the same side, it does not matter which one you attach the feed to. If you are still struggling reverse the connections or check the manual included with your new switch. You don't have a ground wire. Many older houses won't have feed wires, but this is okay. The box is grounded to the house already, meaning you won't need one.
Why do I have to have both switches in the on position for the outside light to work? This issue can occur if a traveller is mixed up with the line feed; or if only a 2-wire was pulled between the two switches; or where the feed comes to the light first, and the two switches aren't linked correctly. Because this level of troubleshooting requires a live circuit to determine what's what, call a qualified electrician to do this repair. Not Helpful 0 Helpful 1. I removed a wall switch that had three wires white, black, and ground.
I have installed another light with a shacked switch, but I cannot get the new light to work. What can I do? It's possible that the switch you removed was one of the two that controls the non-functioning light. A switch with three wires could be used for a hall light with a switch at each end. The switch puts power out to one wire or the other, like a valve for water that goes in two directions. Not Helpful 1 Helpful 0. What wires need to be moved to turn on a light with one switch and a fan with another? How do I wire a double switch if there is only 1 black wire, 1 white wire, and a ground coming from my fan and light?
Connect the one black wire to the bottom dark screw of the other already wire configured switch. Essentially, 2 black wires are attached to the bottom dark screw of one switch. It is one black wire from the power source hot wire and a black wire from the neighboring switch.

Include your email address to get a message when this question is answered. Already answered Not a question Bad question Other. Tips Be sure to read the instructions on the switch and on the fixtures to which you are attaching because you need to determine the amps required; they must match that powered by the switch and by the conduit wiring. Mark the wires with masking tape once you know what they do so that you don't get confused later. Place a piece of electrical tape across the circuit breaker once you have it turned off in order to warn others not to switch the breaker on.
Warnings If you feel at all uncomfortable working with electricity, call an electrician.
