Abstract

Ein Schalter (10) weist ein temperaturabhängiges Schaltwerk (11) auf, das ein festes Kontaktteil (26), ein damit zusammenwirkendes bewegliches Kontaktteil (25) sowie ein eine bestimmte Funktionslebensdauer aufweisendes Bimetallteil (23) umfaßt, das in Abhängigkeit von seiner Temperatur das bewegliche Kontaktteil (25) von dem festen Kontaktteil (26) abhebt, wobei die beiden Kontaktteile (25, 26) in einer ersten Schaltstellung miteinander in Anlage sind, um einen durch den Schalter (10) zu leitenden Strom zu führen, und in einer zweiten Schaltstellung voneinander abgehoben sind, so daß der Schalter geöffnet ist. Die beiden Kontaktteile (25, 26) sind derart aufeinander abgestimmt und angeordnet, daß bei Erreichen der Funktionslebensdauer des Bimetallteiles (23) das Schaltwerk (11) in der zweiten Schaltstellung verschweißt wird (Fig. 1).
