Abstract

The switch has a housing (11) with a first lower housing part (15) and a second upper housing part (17) as a closure for the lower part (15). The switch has a temperature dependant switch mechanism (12) fitted in the lower housing part (15). For the switch mechanism (12), a first counter contact (23) is provided on the inner base (22) of the upper part (17). A second counter contact (27) is provided on the inner base (26) of the lower part (15). The switch mechanism (12) makes an electrically conductive connection between the two counter contacts in dependence on its temperature. The two counter contacts (23,27) can be contacted from outside through the associated housing part (14,16). At least the lower housing part (15) is made of insulating material. The second contact (27) is formed as a flat part which is held by a form fit in the lower part (15) as an integral carrier part.
