Step-by-Step Guide
Step 1: Turn Off the Power
Always turn off the power before working on any electrical wiring. Turn off the power at the main circuit breaker box and use an electrical tester to confirm that there is no power flowing to the circuit.
Step 2: Identify the Cables
Identify the cables that are coming into the switch box. A two-way switch requires three wires: a black or red “hot” wire, a white “neutral” wire, and a bare copper or green “ground” wire.
Step 3: Connect the Ground Wire
Connect the bare copper or green ground wire to the green screw on the switch.
Step 4: Connect the Hot Wire
Connect the black or red hot wire to the common screw on the switch. The common screw on a two-way switch is usually black or copper-colored.
Step 5: Connect the Traveler Wires
Connect the two traveler wires to the two remaining screws on the switch. The traveler wires are usually red or white.
Step 6: Install the Switch
After connecting the wires, push the switch back into the switch box and secure it with screws.
Step 7: Test the Switch
Turn the power back on and test the switch to ensure that it is properly wired and functioning correctly.
