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.

A control system is designed to control an interrupter. The interrupter is started by a startup current to interrupt a main electric circuit. The startup current flows through an auxiliary electric circuit and has a current valve equal to or greater than a predetermined value. The control system includes a driving unit and a driven unit. The driving unit includes an intermediate electrical path to be connected to the main electric circuit. The driven unit is to be connected to the auxiliary electric circuit. When an abnormal current having a current value equal to or greater than a prescribed value flows through the intermediate electrical path, the driving unit uses, as a drive source for driving the driven unit, the abnormal current flowing through the intermediate electrical path. The driven unit supplies the auxiliary electric circuit with the startup current by being driven by the driving unit.
