3-Way Circuit Wiring Diagram
A 3-way switch allows control of a single light fixture from two different locations. This setup requires two 3-way switches.

Image: Standard 3-way wiring configuration.
- Turn Off Power: Locate the circuit breaker controlling the switch and turn it OFF. Verify power is off using a voltage tester.
- Identify Wires: In a 3-way setup, you will typically find a Hot/Line wire, a Hot/Load wire, two Traveler wires, and a Ground wire. Label them if necessary.
- Connect Ground Wire: Connect the bare copper or green insulated ground wire from the wall box to the green ground screw on the switch.
- Connect Traveler Wires: Connect the two traveler wires to the two brass screws on the switch. Ensure consistency between both 3-way switches (e.g., if one traveler is connected to the top brass screw on the first switch, connect it to the top brass screw on the second switch).
- Connect Hot/Line or Hot/Load Wire: Connect the Hot/Line wire (from the power source) to the black screw on the first 3-way switch. Connect the Hot/Load wire (going to the light fixture) to the black screw on the second 3-way switch.
- Secure Switch: Carefully fold the wires into the electrical box. Mount the switch to the box using the provided screws.
- Install Wallplate: Attach the decorator wallplate over the switch.
- Restore Power: Turn the power back ON at the circuit breaker.
Single Pole Circuit Wiring
For single-pole applications, the switch controls a light fixture from one location. Connect the Hot/Line wire to one black screw and the Hot/Load wire to the other black screw. Connect the ground wire to the green screw. The brass screws are not used in a single-pole configuration.
Operating Instructions
The BESTTEN 3-Way Decorator Wall Light Switch features a simple rocker paddle for operation.
- Press the top of the paddle to turn the connected light fixture ON.
