ABSTRACT:
A temperature-dependent switch (10) comprises a bimetallic switching mechanism (12) that is arranged in a housing (11) having a first housing part (14) made of insulating material and a second housing part (17). The bimetallic switching mechanism (12) is connected to a first electrode (16) that is guided out of one housing part (14), and coacts with a second electrode (19) that is provided internally on the other housing part (17). The bimetallic switching mechanism (12) comprises a spring element (23), working against a bimetallic disk (29), which carries a movable contact (28) that coacts with the second electrode (19). There is provided laterally on the spring element (23) a retaining extension piece (25) at which it is attached to the first electrode (16).
