The normally closed contacts of this switch are forced open as a follower slides down the slot in the lever arm. The rotating force of a machine guard opens the switch contacts, turning off the control power.

Thermal Plastic Enclosure
The rope-operated safety switches are installed on machines or belts, enabling the stop command at any point of the machine. If an accidental loosening or break of the rope occurs, the normally closed contacts are forced open. The open position is maintained after operation, even if the rope is released.
These rope-operated switches are available right or left hand angle and auto or manual restart. They include an indicator to assure the rope is pretensioned correctly and that the machine is safe to operate.

The hinge operating shaft is designed to be in line with the rotation point of a guard door. As the door is rotated to an open position, the contacts are forced open and the control power of the machine is shut down.

This key-operated safety switch insures that the machine cannot be re-started until the key is installed into the switch. The removal of the key forces the normally closed contacts to open into a safe condition. Return of the key forces the open contacts to close for machine operation.
Also actuated with a key, this switch includes a built-in solenoid for extra protection in strictly controlled areas. Applications may include machines with high inertia and areas with high temperature or voltage.
