Gate installers and security technicians often need a robust key switch to trigger pulse-controlled doors, barriers, or alarm zones.

Why choose it

With two changeover contacts, you can simultaneously switch a load and monitor the switch state, offering flexibility for complex installations.

Ideal use cases

Installation is straightforward: mount the switch on a flat surface, wire the screw terminals through the rear entry, and insert a standard profile half cylinder (not included). The key can only be removed when the switch is in the OFF position, preventing accidental lockout or unauthorized operation.
