Abstract

An electrical switching device includes a switching device socket and terminals. The device also includes a snap-action switch with at least one catch spring. The catch spring carries at least one switching contact stud. The snap-action switch is trippable by a thermobimetal. For thermal influencing the thermobimetal, a heating device with a heating resistor mounted on a metal support is provided. The metal support can be made from a steel plate carrying an electrically insulating layer made from glass. An extensive heating resistor is provided on the insulating glass.
