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).

High-Security Key-Actuated Light Switches
Secure sensitive lighting equipment; these switches have a round key that is difficult to duplicate. The key is required 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.

Cable-Pull Emergency Stop Switches
Immediately cut power by pulling a cable. These switches are often used to turn off production lines and material handling systems in an emergency. All have positive-force, snap-open contacts that open a circuit when actuated, even if a spring fails or the contacts stick. The contacts will remain open until you tension the cable and reset the switch.
Switches with a power indicator illuminate when the cable has been pulled.
Switches with a tension indicator let you visually confirm that tension is set correctly in the system.
Accessory kits (sold separately) simplify the installation of a new switch.

Hazardous Location Cable-Pull Emergency Stop Switches
Safe to use near ignitable gases and dust, the housing on these switches seals in anything that could ignite flammable material. All are UL listed and CSA certified for use in hazardous locations. Yank the cable anywhere along your line to quickly cut power in emergencies. They have positive-force, snap-open contacts that open a circuit when actuated, even if a spring fails or the contacts stick. The contacts will remain open until you tension the cable and reset the switch. Use the tension indicator to visually confirm that they’re reset correctly.

Frame-Mounted Safety Switches
Also known as interlock switches, these ensure the safety of personnel by automatically shutting off power to machinery when an access door opens. Mount the switch to the door frame and mount a key to the door so that the key is inserted into the switch when the door is closed. When the door opens, the key is removed from the switch and the machine shuts down. They’re often used with machine guards.
Style A-F have positive-force, normally closed contacts that will open a circuit when the switch is actuated even if a spring fails or the contacts stick.
IP67 rated switches protect against temporary submersion.
