Breathtaking 3 And 4 Way Switch Wiring

After that connect the black wire from the fixture to a red or white wire leading out of the box to the first 3 way switch.

3 and 4 way switch wiring. A 3 wire nm connects the traveler terminals of the first 3 way switch and the first 4 way switch. Then connect the black wire coming from the fixture to the black wire going to the first 3 way switch. If you understand how to wire a 3 way switch you ll have no issues with a 4 way switch.

Place all the 4 way switches between the two 3 way switches. For more than two switches one or more 4 way switches are added between the 3 way switches. Each pair of traveler terminals should be wired to the traveler wires from one of the 3 way switches in the circuit.

Connect the hot wire from the source to the common terminal on the first 3 way and the hot wire from the lights to the common on the other 3 way. The travelers from one 3 way can be wired to either terminal in a pair but don t mix up the pairs on the 4 way or the circuit won t work properly. With a pair of 3 way switches either can make or break the connection that completes the circuit to the light.

For a 4 way light circuit to work you need two 3 way switches and at least one 4 way switch. A 4 way switch has five terminals. They all must be between the two 3 way switches.

Please leave a comment i. One ground and 4 circuit terminals divided into two matching pairs called travelers. Watch the 4 way switch video below and pay attention.

A 4 way switch is always placed in between two 3 way switches. Now run another length of 3 wire romex from the 4 way switch location to the second 3 way switch location. 4 way switch configurations are used to control lights with three or more switches.
