Abstract

Ein Schalter (10) umfaßt einen ersten und einen zweiten Außenanschluß (11, 14) sowie ein temperaturabhängiges Schaltwerk (19), das in Abhängigkeit von seiner Temperatur zwischen den beiden Außenanschlüssen (11, 14) eine elektrisch leitende Verbindung für einen durch den Schalter zu leitenden elektrischen Strom herstellt. Das Schaltwerk (19) umfaßt ein Schaltorgan (22), das seine geometrische Form temperaturabhängig zwischen einer Schließ- und einer Öffnungsstellung verändert und in seiner Schließstellung den durch den Schalter (10) fließenden Strom führt. Das Schaltwerk (19) umfaßt ferner ein Federelement (21), das mit dem Schaltorgan (22) permanent elektrisch und mechanisch in Reihe geschaltet ist. Die Stellkraft des Federelementes ist weitgehend temperaturunabhängig, wobei das Schaltorgan (22) eine temperaturabhängige Stellkraft aufweist, die in dessen Schleichphase größer ist als die Stellkraft des Federelementes (21).
