Switches
Wall switches control lighting and other loads, from simple single-pole switches to multi-location, dimmer, and smart options. Choosing the right switch means matching the control type (single-pole, 3-way, 4-way), load, and any smart or dimming features.

Frequently Asked Questions
What is the difference between single-pole, 3-way, and 4-way switches?
A single-pole switch controls a light from one location. A 3-way setup uses two switches to control one light from two locations (top and bottom of a stair, for example). A 4-way switch is added between two 3-way switches to control a light from three or more locations.
What is the difference between a switch and a dimmer?
A switch turns a load fully on or off, while a dimmer adjusts the light level. If you want to set brightness, choose a dimmer rated for your load type (LED, ELV, MLV, or incandescent) and verify LED compatibility.
What are smart switches?
Smart switches add app, voice, and schedule control, and can integrate with lighting-control and home-automation systems. They range from standalone Wi-Fi switches to system devices like Lutron Caseta and RadioRA, and may control on/off or dimming.
How do I choose a switch for commercial use?
For commercial work, choose specification- or commercial-grade switches for durability, confirm the amperage and load type, and consider whether the space needs occupancy/vacancy sensing or other code-driven controls in place of, or alongside, manual switches.
