Abstract

Ein Thermoschalter besitzt eine kreisförmige, konkav oder konvex gekrümmte Bimetallscheibe, die sich mit ihrem Rand auf einem Gehäuseteil abstütz und deren zentraler Bereich direkt oder indirekt eine Kontaktzunge beaufschlagt. In ihrem zentralen Bereich weicht die Bimetallscheibe vom Krümmungsradius ab, insbesondere entsteht dadurch eine gegenläufige konkave bzw. konvexe Krümmung mit einem kleineren Krümmungsradius. Durch diese spezielle Formge­ bung wird bei Unterschreitung der Rückstelltemperatur das Rückspringen verhindert, was bei bestimmten Anwendungs­ fällen nicht mehr erwünscht ist. Durch dieses Verhalten ist der Thermoschalter ausschließlich durch mechanische Ein­ wirkung von außen wieder in seinen Ausgangszustand zurückzuversetzen, die erfindungsgemäße Formgebung beeinträchtigt aber das ordnungsgemäße Ansprechen der Bimetallscheibe bei Erreichen der Schalttemperatur nicht.
