Step-by-Step Installation With 2 Wires:

Follow these steps to install a 3-way switch with 2 wires:

Step 1: Turn off the power

Before starting any electrical work, ensure the power supply to the circuit is turned off. Locate the circuit breaker panel and switch off the corresponding breaker to the circuit you will be working on. Use a voltage tester to verify that there is no live electricity running through the wires.

Step 1

Step 2: Prepare the wires

Carefully strip the insulation from the ends of both wires that will be connected to the switch. Use wire strippers to remove approximately 1/2 inch of insulation, exposing the bare wire.

Step 2

Step 3: Connect the wires to the switch

Attach one wire to the common terminal screw on the switch. This is typically a darker-colored screw, differentiating it from the other two traveler terminals. Connect the second wire to one of the traveler terminals, leaving the remaining traveler terminal empty. Tighten the screws securely to ensure a reliable electrical connection.

Step 3

Step 4: Connect the grounding wire

If your electrical system includes a grounding wire, connect it to the grounding terminal on the switch. This terminal is usually green and located towards the bottom of the switch. Ensure the grounding wire is securely fastened to prevent any potential electrical hazards.

Step 4

Step 5: Mount the switch

Once all the wires are securely connected, carefully position the switch in the electrical box. Use the provided screws to fasten the switch to the box. Ensure that the switch is level and snugly fitted to prevent any movement that could affect its functionality.
