ABSTRACT:
A switch having a housing which receives a temperature-dependent switching mechanism is described, the housing having an electrically conductive lower part as well as an electrically insulating cover part, closing off the lower part and attached thereto, on whose inner side a first countercontact, to which through contact is made externally, is provided for the switching mechanism. The lower part serves as the second countercontact of the switching mechanism and creates, as a function of its temperature, an electrically conductive connection between the two countercontacts. Arranged on the cover part in lossproof fashion are a first connection electrode that is connected electrically to the first countercontact, as well as a second connection electrode that is electrically connected to the lower part as a consequence of the attachment of the cover part to the lower part.
