Abstract

Ein temperaturabhängiger Schalter (10) umfaßt ein Bimetall-Schaltwerk (12), das in einem Gehäuse (11) mit einem ersten Gehäuseteil (14) aus Isoliermaterial und einem zweiten Gehäuseteil (17) angeordnet ist. Das Bimetall-Schaltwerk (12) ist mit einer aus dem einen Gehäuseteil (14) herausgeführten ersten Elektrode (16) verbunden und wirkt mit einer zweiten Elektrode (19) zusammen, die innen an dem anderen Gehäuseteil (17) vorgesehen ist. Das Bimetall-Schaltwerk (12) umfaßt dabei ein gegen eine Bimetall-Scheibe (29) arbeitendes Federteil (23), das einen beweglichen Kontakt (28) trägt, der mit der zweiten Elektrode (19) zusammenwirkt. An dem Federteil (23) ist seitlich ein Halteansatz (25) vorgesehen, an dem es an der ersten Elektrode (16) befestigt ist.

A temperature-dependent switch (10) comprises a bimetallic switching mechanism (12) which is arranged in a housing (11) with 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) led out of one housing part (14) and interacts with a second electrode (19) which is provided on the inside of the other housing part (17). The bimetallic switching mechanism (12) comprises a spring part (23) working against a bimetallic disc (29) which carries a movable contact (28) which interacts with the second electrode (19). On the spring part (23) there is a holding attachment (25) on the side, to which it is attached to the first electrode (16).
