Product Description

Technical Information:

The water-protected WZF Safety Switch with separate actuator is a safety switch with forced operation. It is very robust and features a long actuating travel. Thus an unwanted shutdown of the machine by vibration of the protective device is avoided. When the actuator is pulled out of the switch the contact is forced to open.

Supplied Complete with BB-MS Actuator
Other Actuator Available on Request


  • Especially robust construction
  • A long actuation travel (8.0mm) from initial contact to stop, thus no unwanted turning off of the machine due to vibration from the door or gate.
  • Two contacts, positively driven normally closed and normally open contact
  • Contact movement visible through transparent cover
  • Attachment bases made of metal for secure fixation, rotatable for change of the hole spacing
