Safety switch in compact design

The small water-protected safety switch WZK with separate actuator is a safety switch with forced actuation and is equipped with maximum three contacts. The switch is especially small and therefore suited for reduced space conditions. The actuator is mounted at the door leaf. When pulling the actuator out of the switch a forced opening of the contact is made. The cable is already connected to the switch and included in the scope of delivery.





  • compact, square design with up to three contacts
  • actuation lateral or frontal
  • switch can be screwed on in four positions for actuation from all sides
  • actuator is ejected
  • connection cable firmly attached
  • fixing screws, pressure plate and actuator (BBK) included in the scope of delivery
