Power Switch Light Switch 3 Way

With a pair of 3 way switches either can make or break the connection that completes the circuit to the light.

Power switch light switch 3 way. This 3 way light switch diagram shows connections when the power comes into the first switch on to the second switch and then on to two or more lights switched by the 3 way circuit. Wiring a 3 way light switch. The white wire from the switch connects to the black wire from the circuit power supply cable. In this light switch wiring diagram the power feed joins the circuit via the light fixture where a two wire cable c2 runs from the light to the first 3 way switch sw1 and a 3 wire cable c3 joins the two switches.

When wiring a 3 way switch circuit we will be using a 3 wire cable known as romex coming from the source such as the breaker box. Each 3 way switch in these examples are controlling the power source to the same load. Then a 4 wire cable going between the two 3 way switches and then a 3 wire cable going from the switches to the load. Wiring a 3 way light switch is certainly more complicated than that of the more common single pole switch but you can figure it out if you follow our 3 way switch wiring diagram.

Three way light switch with power feed via the light. This switchlight is designed for single 3 way light switches where two or more light switches control a set of overhead lights.
