Die neuartige Konstruktion der Eohtaktfinger, deren Eontakte a) in Schaltgeräten auf EontaktTdahnen "b gleiten, besteht darin, dass der HebelwinkelCfc der beispielsweise aus Messing in L-lorm hergestellten federnden und stromführenden Metallstreifen c, welche mit Blattfedern d unterstützt werden können, durch die Anordnung eines Begrenzungshalters e beschränkt wird* Dadurch kann der mit oder ohne Unterstützung der Blattfedern federnde Metallstreifen c auch bei Montagen, Reparaturen, Untersuchungen nicht mehr über das Maß des Winkels Φ- hinausgebogen werden. Dieses Überbiegen der Metallstreifen war meist die Ursache der Ermüdungserscheinungen und Brüche der Metallstreifen sowie Schwächung des Eontakt drucke s und Wirkungslosigkeit der Eontakte. Diese Nachteile werden durch die neuartige Eonstruktion der Eontaktiinger beseitigt»The novel construction of the Eohtaktfinger, whose Eontakts a) slide in switching devices on EontaktTdahnen "b, consists in that the lever angle Cfc of the resilient and current-carrying metal strips c, made for example of brass in L-shape, which can be supported with leaf springs d, through the This means that the metal strip c, which is resilient with or without the support of the leaf springs, can no longer be bent beyond the dimension of the angle Φ- even during assembly, repairs and examinations. This overbending of the metal strips was usually the cause of fatigue and fractures the metal strips as well as weakening of the contact pressure and ineffectiveness of the contact. These disadvantages are eliminated by the new construction of the contact »
