Description

Zwischen den beiden Seitenplatten 10 des Schalters ist die Schwenkachse 11 für die Betätigungswippe 12 gelagert. Diese Betätigungswippe weist in an sich bekannter Weise einen Schaltnocken 13 auf, der in der Ausschaltstellung die Kontaktfedern 14 von den Kontakten 15 abhebt.The pivot axis 11 for the rocker switch 12 is mounted between the two side plates 10 of the switch. This rocker switch has in In a manner known per se, a switching cam 13 which, in the switched-off position, contacts the contact springs 14 stands out from the contacts 15.

Die Betätigungswippe 12 weist eine rechteckige Ausnehmung 16 auf. An einer der Stirnwände 17 der Ausnehmung 16 liegt ein Kontaktfederpaar 18, das durch Schlitzausnehmungen der Wippe nach unten geführt ist und in Einschaltstellung (Fig. 1) mit den Enden 19 an den Anschlußklemmen 20 des Wippenschalters anliegt. In die Ausnehmung 16 ist die aus Fig.4 ersichtliche, aus Abdeckplatte 21, Glimmlampe 22 und Vorwiderstand 23 bestehende Baueinheit einklemmbar. Zu diesem Zweck weist die Betätigungswippe 12 am oberen Rand der Ausnehmung 16 eine Stufe 24 auf, die als Träger der transparenten, vorzugsweise rot gefärbten Abdeckplatte 21 dient. Diese Abdeckplatte 21 trägt seitliche Längsstege 25 sowie an den Stirnseiten angeordnete federnde Laschen 26, deren am Ende angeordnete Sperrnasen 27 in Ausnehmungen 28 in den Stirnwänden einrasten.The rocker switch 12 has a rectangular recess 16. On one of the end walls 17 of the Recess 16 is a contact spring pair 18, which through slot recesses of the rocker down is performed and in the on position (Fig. 1) with the Ends 19 rests against the terminals 20 of the rocker switch. The recess 16 is off FIG. 4 shows a structural unit consisting of a cover plate 21, a glow lamp 22 and a series resistor 23 pinchable. For this purpose, the rocker switch 12 has on the upper edge of the recess 16 a step 24, which serves as a support for the transparent, preferably red-colored cover plate 21. This cover plate 21 carries lateral longitudinal webs 25 and resilient tabs arranged on the end faces 26, the locking lugs 27 of which are arranged at the end snap into recesses 28 in the end walls.

An den Ecken der Abdeckplatte 21 sind Zapfen 29, 30, 31, 32 angeformt. In den Zapfen 29 und 30 wird der Vorwiderstand 23 mittels seiner Anschlußdrähte 33 gehaltert, die in einem durchgehenden Schlitz 34 des Zapfens 29 bzw. einem nicht durchgehenden Einschnitt 35 des Zapfens 30 gehaltert sind. In dem Einschnitt 35 stützt sich der eine Anschlußdraht 33 axial ab, während der gegenüberliegende Draht 33 über den Schlitz 34 vorsteht und eine Kontaktklemme bildet, die mit einer der Kontaktfahnen 18 in Kontaktberührung gelangt. Der eine Zuführungsdraht 36 der Glimmlampe 22 ist an den Vorwiderstand 23 angeschlossen, während der andere Zuführungsdraht 37 um den Zapfen 31 geschlungenAt the corners of the cover plate 21 pins 29, 30, 31, 32 are formed. In pins 29 and 30 the series resistor 23 is held by means of its connecting wires 33, which are in a continuous Slot 34 of the pin 29 or a non-continuous incision 35 of the pin 30 are supported. In the incision 35 one connecting wire 33 is supported axially, while the opposite one Wire 33 protrudes beyond slot 34 and forms a contact clip that connects to one of the contact tabs 18 comes into contact. One lead wire 36 of the glow lamp 22 is connected to the series resistor 23 connected, while the other lead wire 37 is looped around the pin 31

ίο ist und mit der anderen Kontaktfahne 18 in Kontaktberührung gelangt, wenn die aus F i g. 4 ersichtliche Baueinheit in die Betätigungswippe 12 eingesetzt ist. Wie aus F i g. 2 ersichtlich, weist die Betätigungswippe am Rand der Ausnehmung 17 zwei kleine Ein- schnitte 38 auf, in die ein Werkzeug, z. B. eine Nadel, ein kleiner Schraubenzieher od. dgl., eingeführt werden kann, um die Abdeckplatte mit der Signallampenkombination aus der Ausnehmung 16 herauszuheben. ίο and is in contact with the other contact lug 18 arrives when the from F i g. 4 visible structural unit is inserted into the rocker switch 12. As shown in FIG. 2, the rocker switch on the edge of the recess 17 has two small single cuts 38 into which a tool, e.g. B. od a needle, a small screwdriver. Like. Introduced can be to lift the cover plate with the signal lamp combination out of the recess 16.

Die Abdeckplatte 21 schließt die Betätigungswippe 12 auf der Oberseite bündig und fugenlos so fest ab, daß sie ohne Werkzeug nicht entfernt werden kann. Die Befestigung des Kontaktfederpaares 18 erfolgt am Boden der Betätigungswippe 12 über KerbnägelThe cover plate 21 closes the rocker switch 12 on the top flush and seamlessly so firmly that that it cannot be removed without tools. The contact spring pair 18 is fastened on the bottom of the rocker switch 12 via grooved nails

39. Die Federwirkung der Kontaktfedern 18 auf den Klemmenbefestigungsschrauben ist so gering, daß dadurch die Bewegung der Betätigungswippe nicht beeinträchtigt wird.39. The spring action of the contact springs 18 on the terminal fastening screws is so small that it the movement of the rocker switch is not impaired.
