Abstract

Der Thermobimetallschalter besteht aus einem flachen, elektrisch isolierenden Träger (1), wenigstens zwei an dem Träger (1) befestigten elektrischen Anschlußteilen (3,4), von denen eines mit einem auf dem Träger angeordneten Fes­ tkontakt (10) und eines mit einer Kontaktfeder (8) Verbindung hat, die mit ihrem einen Ende am Träger (1) befestigt ist und an ihre, anderen Ende ein bewegliches, mit dem Festkontakt (10) zusammenarbeitendes Kontaktstück (9) trägt. Der Träger (1) ist eine dünne Aluminiumoxidkeramikplatte. The bimetallic switch consists of a flat, electrically insulating carrier (1), at least two on the Carrier (1) attached electrical connectors (3,4), of one with a fixed on the carrier tkontakt (10) and one with a contact spring (8) connection has one end attached to the support (1) and at its other end a movable one, with the fixed contact (10) cooperating contact piece (9) carries. The carrier (1) is a thin alumina ceramic plate.
