Power Switch Light Switch 3 Way

Each 3 way switch in these examples are controlling the power source to the same load.

Power switch light switch 3 way.

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. This switchlight is designed for single 3 way light switches where two or more light switches control a set of overhead lights. 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. With a pair of 3 way switches either can make or break the connection that completes the circuit to the light.

The white wire from the switch connects to the black wire from the circuit power supply cable. 1 circuit power supply cable 2 electrical box where the light fixture is mounted 3 4 these wires must be connected to the common screw 5 light fixture. Three way light switch with power feed via the light. 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.
