3 Way Switch Wiring Diagram

Take a closer look at a 3 way switch wiring diagram. Pick the diagram that is most like the scenario you are in and see if you can wire your switch! This might seem intimidating, but it does not have to be. With these diagrams below it will take the guess work out of wiring. Interested in a 4 Way Switch Wiring Diagram?

3-Way Switch Wiring Diagram with LINE and LOAD in the Same Switch Box. In the above diagram the white wire must be re-identified as a hot wire at each switch location. The white wire between switches is not being used as a neutral. An example of three-way switch wiring with the LINE and LOAD in the same 4″ square electrical box.

Wiring a 3-Way Light Switch. 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.. With a pair of 3-way switches, either can make or break the connection that completes the circuit to the light.

Typical 3-Way Switch Wiring, NM Cable. In the 1st diagram below, a 2-wire NM cable supplies power from the panel to the first switch box. The black (line) wire connects to the common terminal of the first 3-way switch. A 3-wire NM connects the traveler terminals of the first and second 3-way switch together.

Now discussing 3-way light switch wiring diagram as also discussed above the color codes of the wires as having three insulated conductors as black as hot, red as switch wire or called traveler and white as common wire as also shown when light is connected to both black and white wires.

Ceiling Fan 3 Way Switch Wiring. Here, a ceiling fan with a light kit is controlled with two 3-way switches. This is the same arrangement as the second diagram on this page with a fan in place of the light fixture. In this wiring, the source is at SW1 and 3-wire cable runs between each switch and the ceiling fan.

Regardless of what 3-way switch wiring diagram, you’re following, you’ll need to use a 3-wire cable to connect the two 3-way light switches. So what you should see if you have correct 3-wire electrical cable (Romex) is a black (power) white (neutral) and now a 3rd (Red) wire.
