Patent-AnSpfu ch:Patent request: Rastenvorrichtung für Dreh- oder Hebelschalter, die für das Schalten von Wechselstrom bestimmt sind, dadurch gekennzeichnet, daß die Vorrichtung' ungleiche Rastenwirkung für Ein- und Ausschaltung besitzt, so daß die Rastenwirkung für das Einschalten viel stärker als für das Ausschalten ist, um zu erreichen, daß das beim Einschalten auftretende Feuer sehr gering wird und beim Abschalten durch die im Anfang kaum vorhandene Momentwirkung das Abschalten in dem Augenblick erfolgt, wo die Stromkurve durch Null geht.Detent device for rotary or lever switches that are used to switch Alternating currents are determined, characterized in that the device 'unequal Has latching effect for switching on and off, so that the latching effect for switching on is much stronger than for switching off is to achieve that the fire that occurs when switching on is very low and when switching off Due to the momentary effect hardly present at the beginning, the switch-off takes place at the moment when the current curve goes through zero. *) Von dem Patentsucher ist als der Erfinder angegeben worden:*) The patent seeker stated as the inventor: Friedrich Schoof in Epstein i. Taunus.Friedrich Schoof in Epstein i. Taunus.
