Three way switches can commonly be found at either end of a hallway near the doors of a very large room with multiple entryways or at the top and bottom of a set of stairs.
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.
A three way switch is built and wired a little differently than a conventional single pole light switch.
The source hot wire is spliced to the common on the dimmer and the neutral is splice through to the light fixture.
These diagrams illustrate how to wire a pair of three way light switches in three different situations.
With a pair of 3 way switches either can make or break the connection that completes the circuit to the light.
With a three way dimmer you can control a light with two switches.
A ground wire a hot lead wire and two travelers to allow for a connection to another switch or outlet.
3 way dimmer switches typically come with the following pre wired leads.
Wiring a standard 3 way dimmer switch.
They allow you the ability to turn the lights on or off from either location.
