Definitions
- the invention relates to a rotary switch or resistor for controls of ventilation, Heating or air conditioning systems in motor vehicles.
- Such controls are used in the dashboard or in the vehicle spars in confined spaces and therefore may not have a certain size exceed.
- automation of mass-produced items progresses, such are here, there is a need for an execution that for the automated manufacturing is suitable and also has small dimensions.
- the contact strip described here as roller-shaped is not suitable for a reliable process Manufacturing operation, the fixation of the conductor track carrier to each other is very complex.
- the object of the invention is one in the preamble of To design the specified rotary switch or resistor such that a reliable production, a simplified fixation of the conductor track carrier to each other and a reduction in the space required can be achieved.
- Fig. 1 shows a section through a knob 1 of a rotary switch or resistor for controls of ventilation, heating or air conditioning systems in motor vehicles from a first housing-fixed base plate 3 with connector strips 4 and one second base plate 5 with conductor tracks 6, with connector strips 4 and conductor tracks 6 in an overlap area 7 via elastic, flexible contact elements 8 are electrically connected.
- the rotary knob 1 projects with driver lugs 9 into one between the base plates 3, 5 existing free space 10, which is filled by a switching or resistance device 11 which is adjusted by the driver lugs 9.
- the contact elements 8 by means of elastomer balls or rollers 12 are formed, which have an electrically conductive layer and in the installed state are elastically deformed and with their restoring force a locking of clipping elements 13 effect that exist between the two base plates 3, 5.
- the elastomer balls or rollers 12 are evenly distributed on the circumference of the base plates 3, 5 and the clipping elements 13 in the center of the base plates 3, 5. Further elastomer balls or rollers 14 can make contact with connecting conductors 15 with the Conduct conductors 6, which themselves do not have to be coated in an electrically conductive manner.
- the exemplary embodiment shows connecting conductors 15 of a plurality of light-emitting diodes 16, which the non-conductive elastomer balls or rollers 14 against electrical contact the conductor track 6 are pressed.
- FIG. 2 shows a view of the base plate 5 with the conductor tracks 6 shown hatched and series resistors 17 for the light emitting diodes 16 and resistance or wiper tracks 18, which are traversed by a switch grinder (not shown).
- the series resistors 17 can be printed, evaporated or spread.
- the elastomer balls or rollers 12, 14 are shown schematically as circles, the elastomer balls or rollers 12 interacting with the connector tracks 4.
- the clipping elements 13 are shown, which are in the locking position with a clipping attachment 19.
- the restoring force of the deformed elastomer balls or rollers 12, 14 causes a locking force which is supported by the clipping projections 19.
- a front panel frames the rotary knob 1 and carries symbols 21, which are illuminated by a light guide arrangement 22.
- the elastomer balls or rollers 12, 14 rest in recesses 23 of the first base plate, i.e. H. these are installed before the base plates 3, 5 through z. B. inserted a machine.

Claims (2)
- Drehschalter oder -widerstand für Bedienelemente von Lüftungs-, Heizungs- oder Klimaanlagen in Kraftfahrzeugen, gebildet aus einer ersten gehäusefesten Grundplatte (3) mit Anschlußsteckerbahnen (4) und einer zweiten Grundplatte (5) mit Leiterbahnen (6), wobei Anschlußsteckerbahnen (4) und Leiterbahnen (6) in einem Überlappungsbereich (7) über elastische nachgiebige Kontaktelemente elektrisch leitend verbunden sind, und wobei die Kontaktelemente (8) durch Elastomerkugeln oder -walzen (12) gebildet sind, die eine elektrisch leitende Schicht aufweisen und im eingebauten Zustand elastisch verformt sind und mit ihrer Rückstellkraft eine Verriegelung von Verklippselementen (13) bewirken, die zwischen den beiden Grundplatten (3, 5) bestehen.
- Drehschalter oder -widerstand nach Anspruch 1, dadurch gekennzeichnet, daß die Elastomerkugeln oder -walzen gleichmäßig am Umfang der Grundplatte (3, 5) verteilt angeordnet sind und die Verklippselemente (13) im Zentrum der Grundplatten (3, 5).
