Description

Stufenschalter, insbesondere für Rundfunk- und Nachrichtengeräte Zusatz zum Patent 72777o Die vorliegende Erfindung befaßt sich mit einer Weiterentwicklung des Stufenschalters nach Patent 727770. Während das Hauptpatent einen Stufenschalter behandelt, bei dem der Kontaktarm einer Kontaktbrücke nacheinander kreisförmig angeordnete Stufenkontakte berührt und die Stromzuführung zur Kontaktbrücke über eine zentrale Kontaktspitze erfolgt, werden bei dem Stufenschalter gemäß der vorliegenden Erfindung durch die Kontaktbrücke einander gegenüberliegende Kontakte leitend verbunden. Es können min eine oder zwei voneinander isolierte federnde Kontaktbrücken - angeordnet werden, die beim Drehen der Schalterachse einander gegenüberliegende Kontakte leitend verbinden. Eine besondere Anordnung zur Strorrlzuführung für diese Kontaktbrücken ist also nicht notwendig.Step switch, especially for radio and communications equipment Addition to patent 72777o The present invention is concerned with a further development of the step switch according to patent 727770. While the main patent deals with a step switch, in which the contact arm of a contact bridge touches step contacts arranged in a circle one after the other and the power supply to the contact bridge over If a central contact tip takes place, in the tap changer according to the present invention, opposing contacts are conductively connected by the contact bridge. At least one or two resilient contact bridges isolated from one another can be arranged, which conductively connect opposing contacts when the switch axis is turned. A special arrangement for the power supply for these contact bridges is therefore not necessary.

Die Erfindung betrifft nun eine für die Massenfertigung besonders zweckmäßige Anordnung für derartige Kontaktbrücken im Schaltergehäuse. Es wird vorgeschlagen, die Kontaktbrücken lose auf einem zentralen Zapfen des Kontaktbrückenträgers aufzustecken, durch welchen .die Drehachse hindurchgeführt, und die Mitnahme der Kontaktbrücke in beiden - Drehrichtungen mittels auswählbarer Stifte, Nasen oder Vorsprünge am Kontaktbrückenträger zu bewirken. Man erreicht dadurch eine Isolation der Kontaktbrücke von der Drehachse des Schalters, welche auch eine Anordnung mehrerer Schalter hintereinander ermöglicht, da die Kontaktbrücke in ihrer Mitte eine größere Durchbrechung besitzt.The invention now relates to one particularly for mass production expedient arrangement for such contact bridges in the switch housing. It is suggested, attach the contact bridges loosely to a central pin of the contact bridge carrier, through which .the axis of rotation passed, and the entrainment of the contact bridge in both - directions of rotation by means of selectable Pens, noses or To cause projections on the contact bridge carrier. This creates an isolation the contact bridge from the axis of rotation of the switch, which is also an arrangement of several Switches one behind the other allows, since the contact bridge in its middle has a larger one Has breakthrough.

Durch den am Kontaktbrückenträger ange; ` ordneten hohlen zylindrischen Zapfen stix sich der Kontaktbrückenträger am Gehäts'!>, deckel ab, falls die Drehachse bei der @ed nung des Schalters von Hand längsachsig verschoben wird.Through the attached to the contact bridge support; `arranged hollow cylindrical The contact bridge carrier is located at the pin!>, Cover, if the axis of rotation is moved longitudinally by hand when operating the switch.

In der Zeichnung ist der Erfindungsgegenstand an einem Äusführungsbeispiel dargestellt.In the drawing, the subject matter of the invention is based on an exemplary embodiment shown.

Fig. i zeigt einen Hauptschnitt durch den Stufenschalter und Fig. -2 eine Draufsicht, nachdem der Deckel mit den Stufenkontakten entfernt wurde.Fig. I shows a main section through the tap changer and Fig. -2 a top view after the cover with the step contacts has been removed.

Das Gehäuse i ist durch den Deckel 2 ab- _ geschlossen, an dem durch `iete 3 die U-förmigen Stufenkontakte q. befestigt sind. Im Gehäuse i ist in an sieh bekannter Weise eine zur Befestigung dienende Gewindebuchse 5 eingenietet, durch welche die Drehachse 6 hindurchragt. Die Drehachse nimmt bei ihrer Drehung den Kontaktbrückenträger 7 mit und dieser mittels der Stifte 7a die Kontaktbrücke B. Wird die Drehachse 6 von Hand nach oben verschoben, so stützt sich der Kontaktbrückenträger durch den zylindrischen Hohlzapfen 7 i, am Gehäusedeckel 2 ab.The housing i is closed by the cover 2, on which through `iete 3 the U-shaped step contacts q. are attached. In housing i, in is on see, in a known manner, a threaded bushing 5 used for fastening is riveted in, through which the axis of rotation 6 protrudes. The axis of rotation decreases as it rotates the contact bridge carrier 7 with and this by means of the pins 7a the contact bridge B. If the axis of rotation 6 is moved upwards by hand, the contact bridge carrier is supported through the cylindrical hollow pin 7 i, on the housing cover 2.
