Abstract

Bei einem Thermoschalter zur Temperaturüberwachung elektrischer Wärmegeräte ist die Kontaktzunge einstückig mit einer Anschlußfahne hergestellt und bis auf einen relativ kurzen Längenbereich starr, so daß bei Beaufschlagung der Kontaktzunge durch die Bimetall-Springscheibe eine schar­ nierähnliche Bewegung der Kontaktzunge erzeugt wird.
Durch die einstückige, starre Ausgestaltung dieses als Anschlußfahne und Kontaktzunge wirkenden Bauteils lassen sich die geometrischen Bedingungen innerhalb des Thermo­ schalters, insbesondere der Abstand der Kontaktzunge von der Bimetall-Springscheibe sehr viel besser in engen Tole­ ranzen halten als bei bekannten Blattfedern als Kontaktzun­ ge. Hierdurch wird ein zuverlässigeres Schaltverhalten und damit eine Qualitätsverbesserung bei der Serienfertigung sowie eine Reduzierung der Herstellungskosten erreicht.
Bei einer besonders einfachen Ausgestaltung ist vorge­ sehen, daß anstelle der Nieten, die zur Befestigung der beiden Anschlußfahnen am Trägerblock dienen, aus den Anschlußfahnen entsprechende Teile ausgestanzt und aus­ geformt sind, so daß die gesamt Teileanzahl für den Thermoschalter auf vier Teile reduziert werden kann, wobei im Unterschied zu bekannten Lösungen die Bimetallscheibe keinen Kontakt trägt.
Die erfindungsgemäße Lösung erlaubt auch in einfacher Weise eine Halterung und Führung der Bimetall-­ Springscheibe, die ein leichtes Einsetzen bzw. Auswechseln der Bimetall-Springscheibe in den fertig montierten Thermo­ schalter erlaubt.
