Step-by-Step Guide to Wiring a 1 Gang 3 Way Switch
Now that you understand the basics of the wiring diagram, it’s time to start wiring the switch. Follow these step-by-step instructions:
Step 1: Turn Off Power
The first step when working with electrical wiring is to always turn off the power at the circuit breaker. Once you have turned off the power, double-check to ensure there is no power present using a voltage tester.
Step 2: Remove Old Switch
Remove the old switch from the electrical box by unscrewing the screws holding the switch in place. Carefully remove the wires from the old switch, making note of which wire goes where.
Step 3: Install New Switch
Install the new switch in the electrical box, screwing it in place using the screws from the old switch. Connect the wires to the new switch, making sure to connect them to the same terminals as the old switch.
Step 4: Connect Common Wires
Connect the black wires from the two 3-way switches together with a wire nut. This is the common wire and provides power to the light fixture.
Step 5: Connect Traveler Wires
Connect the red traveler wire from one switch to the red traveler wire on the other switch using a wire nut. This allows the switches to communicate with each other and control the light fixture.
Step 6: Connect Neutral and Ground Wires
Connect the white neutral wire and bare/green ground wire to the appropriate terminals on the switch.
