with hinged cover
The water-protected safety switch with separate actuator and hinged cover WZA… is a safety switch with forced actuation and is used to control the close position of lift doors and protective enclosures. With the infinitely variable revolving drive head it can be actuated from any direction and allows small swiveling radii. The actuator is mounted at the door leaf. When pulling the actuator out of the switch a forced opening of the contact is made.
