Wilhelm Rabus in Heidenheim a. Br., Württbg.Wilhelm Rabus in Heidenheim a. Br., Württbg. Drehschalter mit in der. Schaltwalze angeordneten federnden Kontaktstiften.Rotary switch with in the. Shift drum arranged resilient contact pins. Patentiert im Deutschen Reiche vom 1. Dezember 1922 ab.Patented in the German Empire on December 1, 1922.

Es sind elektrische Drehschalter bekannt, bei welchen federnde Kontaktstifte starr durch Kontaktbügel verbunden sind. Diese Einrichtung hat den Nachteil, daß sie eine genau gleiche Stifthöhe und gleiche Federstärke voraussetzt; trifft diese Voraussetzung nicht zu; so liegt der Kontakt nicht vollständig auf dem Gegenkontakt auf, es entsteht Funkenbildung, oder die Kontaktvorrichtung versagt. Es kann aber auch der Fall eintreten, daß sich dieThere are electrical rotary switches known in which resilient contact pins rigidly through Contact clips are connected. This device has the disadvantage that it is an accurate requires the same pen height and spring strength; does not this condition apply; so the contact is not completely on the mating contact, sparking occurs, or the contact device fails. But it can also happen that the

Kontakte im Gebrauch ungleich abnutzen. Auf jeden Fall erfordert diese Konstruktion eine große Aufmerksamkeit in der Herstellung und im Gebrauch.Contacts wear unevenly during use. In any case, this construction requires a great deal of attention in manufacture and use.

Die vorliegende Erfindung betrifft nun einen Drehschalter, bei welchem dieser Nachteil vermieden ist. Die Erfindung besteht darin, daß die Kontaktstifte einzeln in der! Schaltwalze beweglich sind und daß der Kontaktbügel gelenkartig mit diesen verbunden ist, so daß jeder Kontaktstift für sich unab'-hängig vom andern in achsialer Richtung federnd gleiten kann, während die Schaltwalze selbst ihre achsiale Lage beibehält. Dadurch wird erreicht, daß die Kontakte gut anliegen und keine Klemmungen entstehen können. Jeder Kontaktstift ist mit einer Schraubenfeder versehen, wodurch eine dauernd sichere Kontaktherstellung gewährleistet ist.The present invention now relates to a rotary switch in which this disadvantage is avoided. The invention consists in that the contact pins individually in the! Shift drum are movable and that the contact bracket is connected to it in an articulated manner so that each contact pin is independent of the other in the axial direction Can slide resiliently while the shift drum itself maintains its axial position. Through this it is achieved that the contacts are in good contact and that no jamming can occur. Each contact pin is provided with a helical spring, which means that it is always safe Establishing contact is guaranteed.

In dem aus Isoliermaterial hergestellten Sockel β ist die Achse & drehbar gelagert, der obere Teil demselben ist mit einem Vierkant zur Mitnahme der ebenfallsao The new rotary switch is in the drawing in one embodiment in cross section shown.

In letzterer sind achsiale Bohrungen d angeordnet, in welchen die beweglichen Kontaktstifte e gleitend sitzen; diese werden durch Schraubenfedem / gegen die 30 Anschlußkontakte g gedrückt und schleifen beim Schalten über Nocken h. Die Kontaktstifte sind durch einen gelenkartig angeordneten Metallbügel i leitend miteinander verbunden und werden durch diesen gleichzeitig 35 am Herausfallen gehindert. Die Schaltwalze wird dabei durch den Druck der Federn / gegen den Griff k in gleicher Höhenlage gehalten. provided shift drum c made of insulating material. Axial bores d are arranged in the latter, in which the movable contact pins e are slidably seated; these are pressed by helical springs / against the 30 connection contacts g and drag over cams h when switching. The contact pins are conductively connected to one another by a metal bracket i arranged in a hinge-like manner and are at the same time prevented by this from falling out. The shift drum is held at the same height by the pressure of the springs / against the handle k.
