Choosing an Electrical Switch

Multi-Way Toggle Light Switches

Often used in large, open workspaces, these switches can be wired on opposite ends of the room to control lights on the same circuit. With a protruding switch, they’re easily flipped on and off. These switches fit standard wall plates (not included).

Three-way switches work in pairs to control lights from two different locations.

Switches with spring clamp terminals install quicker than those with screw terminals. To install, push stripped wire into the clamp for a secure connection.

Wall switch lockouts (sold separately) mount over switches to secure them in the on or off position.

Multi-Way Rocker Light Switches

Also known as three-way switches, these are often used in large, open workspaces and can be wired on opposite ends of the room to control lights on the same circuit. They work in pairs to control lights from two different locations. Actuate the switch by pressing on the wide, flat area. With a slim, low-profile design, they protrude less than toggle switches. All fit standard wall plates (not included).

Switches with spring-clamp terminals install quickly to create a secure connection. Just push a stripped wire into the clamp—no need to bend wire and screw it down.

Wall switch lockouts (sold separately) mount over switches to secure them in the on or off position.

Multi-Way Key-Actuated Light Switches

Also known as three-way switches, these are often used in large, open workspaces and can be wired on opposite ends of the room to control lights on the same circuit. They work in pairs to control lights from two different locations. To prevent accidental activation, they require a key to turn lights on and off. They’re keyed alike, so all switches actuate with the same key. They also work with AC motor loads up to 80% of the current rating. All fit standard wall plates (not included).

Easy-Clean Touch Light Switches

Flat and completely smooth, these switches are easy to wipe down. They’re rated NEMA 3R, so they seal out water that could damage the circuitry. They also won’t corrode from mild cleaning solutions. With just a light tap, you can switch lights on and off, even if you’re wearing gloves.

Switches with a stainless steel wall plate resist wear and tear better than switches with a plastic wall plate.

Multi-Way Light Dimmers

Rocker with Slide Dimmer

Toggle with Mini Slide Dimmer

Often used in large, open workspaces, these switches can be wired on opposite ends of the room to control the brightness of lights on the same circuit. They're also known as three-way switches and work in pairs to control lights from two different locations. The actuator to turn lights on and off is separate from the dimmer to maintain a desired lighting level. They fit standard wall plates (not included).
