Single-pole dual-voltage switches control a light or motor from one location, while three-way switches control it from two locations. Four-way switches add control from a third or additional location and typically work with three-way switches at the ends of the circuit, with these switch types supporting 120V to 277V applications when properly rated.

Confirm that the circuit operates within the switch’s 120V to 277V range, then select the wiring configuration that matches the application, such as single-pole, 3-way, 4-way, or 2-wire control. Check the specific switch for neutral-wire needs, load limits, and motor requirements, and follow local electrical codes and installation instructions before connecting the line, load, and traveler wires.

Dual-voltage switches provide on/off control for lighting and motor loads across 120 V to 277 V circuits, including LED, fluorescent, incandescent, and compatible motor loads. Check the switch’s load type, amperage, wiring, and motor ratings before installation, since LED and fluorescent loads may require neutral wiring or specific compatibility.

Compare the switch’s voltage range, load rating, lighting and motor compatibility, and wiring configuration, such as single-pole, three-way, or four-way, with the requirements of the installation. Also consider whether the project needs local or remote control, a neutral connection, a paddle or digital design, and a finish that coordinates with the wallplate and other controls.
