Safety Considerations When Wiring a 3-Way Switch Keep in mind these were about single light fixtures being controlled by the 3-way switches. Finally, it returns the power-in cable.Once electricity passes through the fixture, it leaves on white neutral wire.From there it would enter the light fixture next. In case the 1 st switch is also up, then the current leaves from 3-way switch common wire that is black in 2-rope cable.And then visit the 1 st switch on the red wire. In case the 2 nd switch is up, it would leave the switch through the traveler terminal.Next, it visits 2 nd switch through the common terminal. There it meets the white wire in 3-rope cable. Then it goes to the 1 st switch box through white wire in a 2-rope cable.Current travels through the black wire and enters the light box to meet white wire where it splices.Have a look at the wiring diagram as well as the explanation. And the light box would have the power-in line entering it. In this next segment of understanding 3-way switch wiring in many ways, let’s focus on a scene where power supply comes down from ceiling.Īnd if this is the case, then running the cables in a way that it goes up in light box at ceiling would work best. Opposite Walls Switch Box Having Power from Ceiling This completes the circuit and light turns on.Ģ.Then the current passes in light to later go back into 2 nd switch through white wire, which meets another white wire staying between both switch boxes in 3-rope.Down position of the 2 nd switch means again exiting but this time through 3 way switch common wire black and enters the light.Down position of the 1 st switch means exiting through the red wire and then visiting through traveler terminal into 2 nd switch.Current enters through the black wire towards the 1 st switch box, attached to the common terminal.Having the same box for more than just one switch and also, other switches get power available. Here are some ways you can wire a 3-way switch: 1. ![]() How to Wire a 3-Way Switch – The 4 Different Ways ![]() Finally, you get the screws tight and firm. Then in a clockwise direction, try wrapping the wire on screw. Also, screws are usually on the side of each switch.įor making connections with the screws, you must get stripped wire end bend and make a half-circle-like shape with it. And here the wire is usually pushed into. Some light switches would come with tiny back holes. And then get it inside the light switch box installed. So many ways you can wire a 3-way switch! And everything goes in vain without enough idea on these two topics.Īs soon as you determine the ideal spot for each wire, you must work on connecting the light switch to right wire.
