ABSTRACT:
A temperature-dependent switch has a temperature-dependent switching mechanism and a housing, receiving the switching mechanism, that has a lower part and an upper part made of insulating material. On the inner side of the upper part there are two stationary contacts, each of which is connected to an external terminal associated with it. A current transfer member is moved by the switching mechanism, which electrically connects the two stationary contacts to one another as a function of temperature. A cavity, into which project two contact surfaces which are each connected to one of the stationary contacts, is located in the upper part.
