Safety switch |
摘要 |
A safety switch includes a housing having at least one opening and supporting a spring-biased tappet which is movable between two end positions by a switching mechanism including a switch wheel received in the housing. The switch wheel includes at each side a pair of separate but operatively interconnected resiliently mounted locking members. Each locking member carries a locking pin which is engageable in a bore of the surrounding housing. An actuator is insertable through the opening to act on ramp surfaces of the locking member, with the ramp surfaces being spaced from the grooves in the switch wheel. Thus, only a very particular actuator of complex configuration is suitable to effect the unlatching and subsequently the turning of the switch wheel for movement of the tappet from the initial position to a switching position.
