Three-way switches let you control the same lights from two locations, while a compatible dimmer or companion control can provide local on-and-off operation and, when supported, lighting-level adjustment. In a smart lighting system, a compatible remote switch can connect with the primary dimmer or switch to support control from multiple locations and coordinated lighting scenes.

Before installation, confirm the circuit uses three-way wiring, identify the line, load, traveler, neutral, and ground conductors, and verify that the switch’s voltage rating matches the application, such as 120V to 277V. Turn off power at the circuit breaker, follow the wiring diagram, and check whether a companion switch requires pairing with a compatible master control for multi-location operation.

Compare the switch’s voltage rating with the circuit voltage, such as 120 V or 277 V, and confirm that the wiring method supports a three-way installation. Check the load rating and load type for the connected lights or motor, noting that the assortment includes 15 A three-way switches for general-purpose loads and 120 V remote companion switches for compatible multi-location controls.

A three-way switch with a locator light can help users find the control in dark or low-light areas, such as hallways, stairways, bedrooms, and garages. It supports convenient lighting control from multiple locations while providing a soft visual reference, with the light typically easier to see on lighter-colored switch finishes.
