Abstract

Das Relais besitzt einen Spulenkörper (1), der vorzugsweise aus Keramik besteht, mit einer Wicklung (2) und einem U-förmigen Kernjoch (5), dessen Enden von einem flachen Anker (9) überbrückt werden. Der Anker betätigt eine isolierende Schaltfeder (14) aus Keramik oder einem ähnlichen Material, welche an ihrem beweglichen Ende mit einem Brückenkontakt (14a) zwei Gegenkontakte überbrückt. Das Relais kann auch bei sehr kleiner Ausführung in hoher Umgebungstemperatur eingesetzt werden.
