Install these key switches in 3/4" dia. panel cutouts. They require a key to turn circuits on or off, limiting access to sensitive equipment.

With a round key that is difficult to duplicate, these switches provide a higher degree of security than standard key switches.

To prevent accidental actuation and limit access to sensitive equipment, these switches require a key to turn circuits on or off. The contact block and actuator are all one piece, so they won’t separate in high-vibration applications.

Designed for use near ignitable gases, fibers, and dust, these switches have a housing that seals in anything that could ignite flammable material. They require a key to turn circuits on or off, preventing accidental activation and limiting access.

These 16 mm switches require a key to turn circuits on or off, limiting access to sensitive equipment.

Choose an actuator and contact block to make your own 22 mm plastic switch.

Immediately cut power with a single push.

Rated NEMA 3S, NEMA 4X, NEMA 13, and IP66, these plastic switches resist corrosion better than aluminum switches and withstand washdowns and oil/coolant spraying.

Secure sensitive lighting equipment; these switches have a round key that is difficult to duplicate.

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.
