Abstract (en)

[origin: EP0794546A2] The switch has a temp. dependent switch mechanism (12) in a housing (11). The housing has a lower part (14) on whose base (15) is arranged a first counter-contact (16) for the switch mechanism. The housing also has a cover (17) to close the lower part (14). A second counter-contact (19) for the switch mechanism is arranged on the inside of the cover. The switch mechanism makes an electrically conductive connection between the two contacts (16,19) in dependence on its temperature. The lower part (14) of the housing (11) is made of insulating material. The first counter contact (16) can be contacted from outside through a wall (13) of the lower part (14). The cover part (17) is made of electrically conductive material and also acts as the second counter-contact (19). The cover part is held on an upper edge of the lower part (14).
