Abstract (en)
[origin: EP0345656A2] In a security switch, comprising a switch part, control part and actuation part, the displacement of the contact plunger in the switch part is caused by rotating a switch-actuating wheel in the control part. This switch-actuating wheel has a plurality of control arms and is mounted so as to be rotatable about a shaft, which in turn can be shifted into or out of a switch-actuating position. The rotation of the switch-actuating wheel and the shifting of the shaft is carried out by the actuation part pushed into a slit of the control part. However, the actuation part shifts the shaft of the switch-actuating wheel into the switch-actuating position only when the actuation part is screwed to a door or the like.
