Description

Es sind elektrische Drehschalter bekannt geworden, an deren Schaltachse besondere Schaltsterne, gegen die sich Federn anlegen, angebracht sind, um ein sicheres Schalten von Rast zu Rast zu erreichen. Verwendet man solche Schalter für höhere Stromstärken, so können die Reibungskräfte derart anwachsen, daß ein Stehenbleiben des Schaltsternes in der Totlage eintritt. Um diesen Übel-ίο stand zu beseitigen, wird nach vorliegender Erfindung am Schaltstern ein ihn umschließender Käfig angebracht, in dem Kugeln oder Rollen, ähnlich wie in Kugellagern, frei beweglich angeordnet sind. Da beim Schalten die Kugeln an den Schaltfedern vorbeirollen, wird die Reibung auf ein Mindestmaß herabgedrückt, so daß ein Stehenbleiben des Schaltsternes außerhalb der Rastenstellungen vermieden ist.
Die Abbildungen zeigen diese Neuerung, und zwar zeigen Abb. ι und 2 einen Schaltwürfel mit Kugelkäfig, Abb. 3 und 4 einen solchen mit Rollenkäfig, α ist der Schaltstern; b sind die Schaltfedern; c ist der Käfig, in dem die Kugeln g bzw. Rollen β as lose gelagert sind. Beim Schalten rollen die Kugeln d über die Schaltfedern b, so daß die Reibungskräfte ausgeschaltet sind. Ein Stehenbleiben des Schaltsternes in der Totlage ist hierbei nicht möglich.Electrical rotary switches have become known, on the switching axis of which special switching stars, against which springs are applied, are attached in order to achieve reliable switching from detent to detent. If such switches are used for higher currents, the frictional forces can increase in such a way that the star switch stops in the dead position. In order to eliminate this bad situation, according to the present invention, a cage surrounding it is attached to the star switch, in which balls or rollers, similar to ball bearings, are arranged to be freely movable. Since the balls roll past the switching springs when switching, the friction is suppressed to a minimum, so that the switching star does not stop outside of the detent positions.
The figures show this innovation, namely show Fig. Ι and 2 a switching cube with a ball cage, Fig. 3 and 4 such a cage with a roller, α is the star switch; b are the switching springs; c is the cage in which the balls g or rollers β as are loosely supported. When switching, the balls d roll over the switching springs b, so that the frictional forces are switched off. It is not possible for the star switch to stop in the dead position.
