Safety switch in especially robust design

The water-protected safety switch WZ with separate actuator is a safety switch with forced actuation and is used to control the close position of lift doors. It is very robust and therefore particularly suitable for lift doors. The actuator is mounted at the door leaf. When pulling the actuator out of the switch a forced opening of the contact is made.


  • especially robust construction
  • one positively driven normally closed contact
  • movement of contacts visible through transparent cover
  • actuator is ejected, if plugged in up to 3 mm before the stop only
  • mounting brackets made of metal for secure fixation
