4 Way Switch Wiring Diagram Power At Light
A 4 way switch has five terminals.
4 way switch wiring diagram power at light. One ground and 4 circuit terminals divided into two matching pairs called travelers. Look for 4 way switch wiring diagram or step how to wire a four way light switch electrical circuit a 4 way switch is a double pole double throw dpdt switch. It has 4 terminals or poles and consists of two 3 way switches that are modified. A 4 way switch wiring diagram is the clearest and easiest way to wire that pesky 4 way switch.
Power from light fixture to light switch. The switch can be used to control the electricity supplying lights from three locations. I have a few of the most common ways in wiring a 4 way switch to help you with your basic home wiring projects. Each pair of traveler terminals should be wired to the traveler wires from one of the 3 way switches in the circuit.
The electrical source is at the first 3 way switch and the hot wire connects to the common there. With nm cable the wire colors for travelers will be black and red using 3 wire cablewith conduit the wire colors for travelers could be any color. The white wire of the cable going to the switch is attached to the black line in the fixture box using a wirenut. Also i dont know how you would wire two light fixtures into this setup.
