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.

Install these key switches in 30 mm dia. panel cutouts. They require a key to turn circuits on or off, limiting access to sensitive equipment.

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

Reset fire panels, or open electromagnetic locks, electric strikes, and automatic door openers. These switches require a key to turn circuits on or off, limiting access and preventing accidental activation.

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

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.

Immediately cut power with a single push.

Often used with machine guards, these switches mount to a door frame.

Delay access to hazardous areas until conditions are safe; use these switches with machines that take time to stop after they are turned off. They mount to a door frame.

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.

Small yet mighty, these switches are about as tall and wide as an index card yet durable enough to mount directly to a wall.

Mount these switches inside your enclosure to prevent it from opening when power is on—actuating the switch disconnects power and releases the door.

Cut power and keep it isolated to prevent equipment from starting up during inspection and maintenance. These switches are housed in a protective enclosure that resists denting, chipping, and cracking.

Stop battery drain and prevent the theft or unauthorized use of equipment by disconnecting batteries when not in use.

Rated IP69K, these switches are protected from high-pressure and high-temperature washdowns.

Prevent motors and other equipment from overheating or failing from not having enough voltage. When the supply voltage falls below 35% of the rated voltage, these switches will automatically turn off to protect the circuit from undervoltage.
