Description

Die Erfindung betrifft einen mehrpoligen eilektrischen Drehschalter mit mindestens vier zwischen festen Kontaktfederpaaren eingreifenden starren, beweglichenM.Lesserkontakten, die an einer Scheibe angeordnet:,sind.The invention relates to a multi-pole electronic rotary switch with at least four rigid, movable M.Lesserkontakts engaging between fixed contact spring pairs, which are arranged on a disk:, are.

Derartige-Drehschalter werden hauptsächlich züi dem Zweck gebaut, um mit einer einzigen Drehbetätigung der Welle mehrere verschiedene Schaltaufgaben zu erfüllen, indem auf der Welle eine entsprechende Anzahl von Kontakten sitzt, die mit ruhenden Gegenkontakten zusammenarbeiten.Such rotary switches are mainly built for the purpose to perform several different switching tasks with a single rotary actuation of the shaft to be fulfilled by having a corresponding number of contacts on the shaft, who work together with dormant counter-contacts.

Der Drehschalter nach der Erfindung zeichnct sich gegenüber den bekannten ähnlichen Schaltern dadurch aus, daß er besonders leicht und einfach den verschiedensten Schaltaufgaben angepaßt werden kann. Dies wird erfindungsgemäß dadurch erreicht, daß an der Wurzel der zahnartigen, aus der Scheibe ausgestanzten. Messerkontakte Kerbe, Rillen od. dgl. vorgesehen sind, die ein Ausbrechen einzelner Kontakte erleichtern.The rotary switch according to the invention is characterized over the known similar switches in that it is particularly easy and simple to use Switching tasks can be adapted. According to the invention, this is achieved by that at the root of the tooth-like, punched out of the disc. Blade contacts Notches, grooves or the like. Are provided that facilitate breaking out of individual contacts.

In der Zeichnung ist als Ausführungsbeispiel der Erfindung eine Kontaktscheibe und ein mit ihr zusammenarbeitender Gegenkontakt eines Drehschalters dargestellt. Abb. 2 zeigt die Anordnung im Onerschnitt nach LinieIJ der Abb. i, welche eine axiale Ansicht dieser Anordnung zeigt.In the drawing, a contact disk is an exemplary embodiment of the invention and a counter contact of a rotary switch that works together with it is shown. Fig. 2 shows the arrangement in single section along line IJ of Fig. I, which is an axial View of this arrangement shows.

Auf einer Vierkantachse i des Drelischafters ist eine Kontaktscheibe 2 aufgesteckt, aus der acht Zähne 3 ausgestanzt sind. An der Wurzel dieser Zähne !sind beiderseits Kerben 4 vorgesehen, die das Abbrechen dieser Zähne erleichtern, so daß es auch von Hand ohne weiteres möglich ist. An dem aus Isoliermateria,1 bestehenden, mit dein Gehäuse des Schalters verbundenen Körper 6 sind mittels Niete 7 die Gegenkontakte befestigt, die aus einem federnden Kontaktpaar 8 und einer Anschlußfahne 9 bestehen. A contact disk 2, from which eight teeth 3 are punched, is pushed onto a square axis i of the Drelischafters. At the roots of these teeth, notches 4 are provided on both sides, which make it easier for these teeth to break off, so that it can easily be done by hand. The mating contacts, which consist of a resilient pair of contacts 8 and a connecting lug 9, are fastened to the body 6 made of insulating material 1 and connected to the housing of the switch by means of rivets 7.

Durch axiale Aneinanderreihung mehrerer solcher Anordnungen auf der Schalterachse i in der Weisie, daß je ein Isolierstück 6 eine Kontaktscheibe 2 von der nächsten trennt, lassen sich Vielfachschalter herstellen. Eis ist klar, daß zwischen dein Schaltgriff und der Schalterachse noch ein Sprungwerk eingeschaltet sein muß, damit die nötige ' Momentschaltung erzielt wird. Dies bildet aber nicht den Gegenstand der Erfindung und ist daher nicht dargestellt und beschrieben.Multiple switches can be produced by axially lining up several such arrangements on the switch axis i in such a way that an insulating piece 6 separates one contact disk 2 from the next. It is clear that a spring mechanism must be switched on between your switch handle and the switch axis so that the necessary ' momentary switching' is achieved. However, this does not form the subject of the invention and is therefore not shown and described.

Durch Ausbrechen von Zähnen können die Schaltscheiben je nach den Bedürfnissen abgeändert und so die verschiedensten Schaltaufgaben erfüllt werden.By breaking out teeth, the switching disks can be modified according to requirements and a wide variety of switching tasks can be performed.
