Abstract

Ein Temperaturwächter (10) mit einem bei Übertemperatur schaltenden Bimetall-Schaltwerk aus Bimetall-Scheibe und stromführender Federscheibe (22) weist einen ersten Heizwiderstand (53) auf, der dem Bimetall-Schaltwerk zugeordnet ist und bei betätigtem Bimetall-Schaltwerk im Sinne einer Selbsthaltefunktion wirkt. Dem Bimetall-Schaltwerk ist ein zweiter Heizwiderstand (54) zugeordnet, der bei zu hohem Stromfluß durch den Temperaturwächter (10) derart wirkt, daß das Bimetall-Schaltwerk schaltet, um so den Verbraucher vor Überstrom zu schützen. Das Bimetall-Schaltwerk ist dabei als Umschalter ausgelegt und so mit den beiden Heizwiderständen (53, 54) verschaltet, daß es in seinen beiden Schaltstellungen jeweils über ein stromführendes Teil (22) den durch den Temperaturwächter (10) fließenden Strom übernimmt.
