Claims (1)

PATENT-ANSPRÜCHE : 1. Anzeigevorrichtung für Stromumkehrung, dadurch gekennzeichnet, dass ein durch einen permanenten Magneten polarisiertes Eisenblechfähnchen zur Anwendung gelangt. PATENT CLAIMS: 1. Display device for current reversal, characterized in that a sheet iron flag polarized by a permanent magnet is used. 2. Anzeigevorrichtung nach Anspruch l, dadurch gekennzeichnet, dass sie zur Anzeige von Rüekzündungen bei Gleichrichtern dient. 2. Display device according to claim l, characterized in that it is used to display backfires in rectifiers. 3. Anzeigevorrichtung nach den Ansprüchen 1 und 2, dadurch gekennzeichnet, dass der bewegliche Blechstreifen (e) von möglichst geringer Masse an einem vom Felde des stromführenden Kabels nicht beeinflussten permanenten Magneten drehbar gelagert ist und von einem vom Felde des Kabels beeinflussten Eisenblech angezogen oder abgestossen wird, wobei die abstossende Kraft von einer Rückschnellfeder unterstützt wird. 3. Display device according to claims 1 and 2, characterized in that the movable sheet metal strip (e) of the lowest possible mass is rotatably mounted on a permanent magnet not influenced by the field of the current-carrying cable and is attracted or repelled by an iron sheet influenced by the field of the cable where the repulsive force is supported by a return spring. 4. Anzeigevorrichtung nach Anspruch 3, dadurch gekennzeichnet, dass durch das Rückschnellen des beweglichen Eisenblechstreifens mittels einer Kontaktvorrichtung ein Relais, eine Registriereinrichtung od. dgl. zum Ansprechen gebracht wird. EMI2.1 4. Display device according to claim 3, characterized in that a relay, a registration device or the like. EMI2.1
