ABSTRACT:
A temperature-dependent switch comprises a temperature-dependent switching mechanism having an electrically conductive spring element carrying a movable contact element. A first counter-contact is provided that coacts with said movable contact element to constitute a first switching contact pair that is opened and closed as a function of the temperature of the switching mechanism. A first heating resistor is provided for influencing the temperature of the switching mechanism at least in one switching state of the latter. The first heating resistor is provided on the movable contact element.
