In the rest position the pin of the GN 816.1 plunger is retracted. To make the pin protrude, push down against the spring force to the final position and turn 90° to lock the pin in the protruding position.
The shape of the cam curve secures the plunger against accidental operation.
For use with key (Type B/BK), a key is required to move the plunger in the same manner as the knurled knob type. In this version, a cover sleeve provides additional security and safety from unauthorized removal of the locking plunger. The cover sleeve also provides additional protection against malfunction caused by dirt.
