Description

Bei den Ölschalteni mit Yorstufenwiderstand steht gewöhnlich der Widerstand im eingeschalteten Zustand fies Schalters dauernd unter Spannung. Da der Widerstand aber nur für den .Schaltvorgang von Bedeutung ist, ist seine dauernde Beanspruchung durch die Betriebsspannung überflüssig, zumal die dünnen Widerstandsdrähte zum Strahlen und zur Erzeugung von Kriechströmen neigen.In the case of the oil shifters with a stage resistor the resistance is usually in the switched-on state of the nasty switch undervoltage. Since the resistance is only important for the switching process is, its permanent stress by the operating voltage is superfluous, especially since the thin resistance wires tend to radiate and generate leakage currents.

Dieser Nachteil wird erfindungsgemäß dadurch vermieden, daß der Widerstand nur während des Einschalt- und Ausschaltvorganges an die Spannung gelegt wird, im eingeschalteten Zustand aber ebenso wie im ausgeschalteten Zustand des Schalters spannungslos ist.This disadvantage is avoided according to the invention in that the resistor only voltage is applied during the switch-on and switch-off process, in the switched-on State but just as in the switched-off state of the switch is de-energized.

In der beiliegenden Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Der Widerstand α ist mit den Kontakten 7» verbunden, die auf der Traverse c gegeneinander und gegen das Schaltmesser d isoliert befestigt sind. Während des Schaltvorganges gleiten diese Kontakte an den festen Gegenkontakten e entlang, kommen aber, sobald die Hauptkontakte sich berühren, wieder außer Eingriff. Die gezeichnete Stellung ist die Einschaltstellung des Schalters.An exemplary embodiment of the invention is shown in the accompanying drawing. The resistor α is connected to the contacts 7 », which are attached to the cross member c in an insulated manner from one another and from the switch blade d. During the switching process, these contacts slide along the fixed mating contacts e , but disengage again as soon as the main contacts touch. The position shown is the on position of the switch.
