Abstract

A miniature safety switch is used in motor vehicle electronics. The miniature safety switch has a housing base, from which a fixed contact arm and a bimetallic contact arm, which has a moving contact and a bimetallic snap disk attached thereto, are led out. A PTC resistor is brought into direct contact with the bimetallic snap disk by a compression spring and is electrically integrated in such a way that, as a result of the heat generated by the PTC resistor, the bimetallic snap disk remains in the open position thereof in the event of triggering.
