3 Way Switch Wiring Diagram Common. It is used when you have three or more switches controlling one light, the middle. Of the three circuit terminals, one is called the common and the other two are known as travelers.
A pair of three-wire cables enter the box of the four-way switch. You can put your lights on a dimmer switch in no time. The white neutral wires are connected together in each switch box.
If the switches are positioned so that the common on both ends is connected to the hot traveler (which could be either traveler), then the circuit is complete and the light comes on.
There are many different wiring diagrams for switched circuits, including three-way and four-way switching, and these diagrams have guided electricians and others for decades.
One three way switch is in the garage and one is in the house. Put a piece of tape on the wire that goes to the common terminal screw. The most common requirement of any hardwired automated light switch is a neutral wire. line-switch-switch-load If your wiring is like either diagram below, you can wire your smart switch in either of your two switch.
