Abstract

Die Erfindung betrifft einen Temperaturschalter zur Überwachung elektrisch beheizter Geräte, welcher eine sichere Halterung der Bimetallscheibe auf der Kontaktfeder gewährleistet, auch wenn der Temperaturschalter durch äussere mechanische Einwirkung beeinflusst wird. The invention relates to a temperature switch Monitoring electrically heated devices, which one secure mounting of the bimetallic disc on the contact spring guaranteed, even if the temperature switch by external mechanical influence is influenced.

Die Bimetallscheibe wird einerseits durch L-förmige, aus der Kontaktfeder ausgestellte Lappen und andererseits durch die an den Längskanten der Kontaktfeder befindliche abge­ winkelte Fortsätze gehalten. The bimetallic disc is made on the one hand by L-shaped the contact spring flaps and on the other hand by the abge located on the longitudinal edges of the contact spring angled extensions held.

Im Bereich der Längskanten der Kontaktfeder sind geschlossene Längsschlitze eingearbeitet, wodurch die abgewinkelten Fortsätze beim Anbringen der Bimetallschei­ be an der Kontaktfeder federnd nach aussen gebogen werden. In the area of the longitudinal edges of the contact spring closed longitudinal slots incorporated, making the angled extensions when attaching the bimetallic disc be resiliently bent outwards at the contact spring will.

Die L-förmig aus der Kontaktfeder ausgestellten Lappen sind mit den zum Zentrum gerichteten Schenkein schräg nach oben gebogen, sodass die dadurch vergrösserte Öffnungsweite zwischen den Schenkelenden und der Kon­ taktfeder ein zügiges Einschieben der Bimetallscheibe gewährleistet. The L-shaped flaps from the contact spring are inclined with the legs facing the center bent upwards so that the enlarged Opening width between the leg ends and the con clock spring a rapid insertion of the bimetal disc guaranteed.
