Single-pole load control switches operate a light or other load from one location, while three-way switches let you control the same load from two locations and require compatible three-way wiring. Multi-gang installations place multiple switches in one electrical box, so installers should plan for box capacity, shared wiring, and a faceplate sized for the number of devices.

Compare the switch’s voltage rating with the circuit voltage, such as 120 V or 277 V, and select a current rating that meets or exceeds the connected load, with many load control switches rated up to 15 A. For motors, pumps, or other high-inrush loads, review the product’s load-type and current specifications rather than relying on the lighting rating alone.

Many electronic or wireless load control switches in this category require a neutral wire, while mechanical switches may use different wiring configurations. During installation, verify the switch’s line, load, neutral, and ground connections, and confirm whether it supports single-pole or three-way wiring before selecting the device.

Mechanical load control switches provide straightforward on/off operation for lighting loads that do not need automation and can support single-pole or three-way installations. Wireless load control switches connect to an automated lighting system, support a range of lighting and motor loads, and can handle high-inrush applications such as fountain pumps or large fluorescent-light banks.
