ABSTRACT:
A temperature-dependent switch (10) has a temperature-dependent switching mechanism (12) and a closed housing (11), receiving the switching mechanism (12), which comprises a lower part (14) as well as an upper part (17) made of insulating material. Two stationary contacts (26, 27) are provided on the upper part (17) on its inner side (28), each of which is electrically connected to an external terminal associated with it. Also provided is a current transfer member (29), moved by the switching mechanism (12), which electrically connects the two stationary contacts (26, 27) with one another as a function of temperature. Two connector electrodes (24, 25) are embedded into the upper part (17), each of which is connected to one of the stationary contacts (26, 27) and to one of the external terminals (38, 39).
