Rated NEMA 4 or IP66, these switches are protected from washdowns.

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.

Sized for 22 mm dia. panel cutouts, these switches require a key to turn circuits on or off, limiting access to sensitive equipment.

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.

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.

Immediately cut power with a single push.

Immediately cut power with a single push.

Made of yellow polycarbonate plastic, these enclosed switches are easy to see and resist dents, chips, and cracks. They are more corrosion resistant than aluminum enclosed switches and withstand washdowns and oil/coolant spraying.

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

Choose an actuator and contact block to make your own 30 mm switch.

Also known as interlock switches, these ensure the safety of personnel by automatically shutting off power to machinery when an access door opens. They’re often used with machine guards.

Prevent accidental activation—these switches require a key to turn lights on and off.

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

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

Keep power running while you access your enclosure. Unlike standard enclosure disconnect switches, which shut off power as you open your enclosure, these have an override function.

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.

With a housing that’s designed to contain an explosion, these switches are safe to use in areas where ignitable concentrations of flammable or combustible gas, dust, or fibers may be present.

Often used in electrical enclosures, these switches mount directly to DIN rails. They cut power and keep it isolated to stop equipment from starting up during inspection and maintenance.

A raintight NEMA 3R rated enclosure protects these switches outdoors.
