Install these switches inside an enclosure to prevent it from opening when power is on—turn the switch to disconnect power and release the door.

Protected by a steel enclosure, these switches withstand tougher conditions than switches in a plastic housing. Also known as safety switches, they have quick-make/quick-break action to eliminate arcing and prolong switch life.

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.

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.

Minimize false triggers—these switches require 10 lbs. of actuation force in order to shut off machinery immediately.
