These safety-interlock switches have slots for inserting keys to actuate the switch and help secure locations and equipment from unauthorized use.

These keys connect to and actuate compatible safety-interlock switches.

Lever- and roller-actuated safety-interlock switches pivot around an axis and activate at preset positions. Lever arms extend from the switch body to provide extra reach and to track different shapes, sizes, or uneven surfaces. Roller actuators provide smooth contact with moving objects to reduce friction, absorb force, and minimize wear.

Actuators make physical contact with objects to connect or disconnect safety-interlock switches from electricity.

These solenoid-actuated safety-interlock switches convert electrical energy into linear motion to open and close their circuits. Solenoid-actuated safety-interlock switches feature an integrated linear actuator that moves when power is applied.

These safety-interlock switches are for hazardous locations where the possibility of flammable gases, vapors, or liquids, ignitable fibers or particles, or combustible dust may exist under normal and abnormal conditions. They have location ratings that classify their suitable environment for operation and must be paired with compatible hazardous-location devices to be compliant with safety standards.

These door safety-interlock switches have plungers that actuate when compressed to open or close a circuit.
