Gelöst wird die Erfindung durch die Merkmale des Patentanspruchs 1.The invention is solved by the features of patent claim 1.

Der Erfindung liegt die Idee zugrunde, einen Drehknopf und eine darin befindliche Taste durch eine Halterung funktional losgelöst voneinander aufzubauen, wodurch bei Verstellung des Drehknopfes die Taste nicht mit verstellt wird. Die Halterung ist dabei die konstruktive Verbindung zwischen dem Drehknopf und der Taste. Die Drehverstellung wird durch den Drehknopf übertragen, während über die separate Taste die Tastfunktion durchgeführt wird. Für die zentrische Ausleuchtung mit gleichzeitig zentrischer Kontaktierung der Taste sorgt ein flexibler Schaltstößel mit einer mittigen Durchführung, um die die Kontakte vorzugsweise kreisringförmig angebracht sind. Das zur Ausleuchtung notwendige Licht kann dabei durch die Durchführung in die Taste eingeleitet werden. So ist ein Gegenstück des Drehknopfes auf der Halterung beweglich gelagert, während die Taste verdrehsicher mit der Halterung verbunden ist. Hierbei liegt der Vorteil darin, daß die Taste nicht extra zu einer Grund- oder Leiterplatte ausgerichtet werden muß, da der Drehsteller als kompaktes Einzelteil ausführbar ist. Bei einer Befestigung des Drehstellers in einer Blende kann dies gleichfalls über die Halterung erfolgen.The invention is based on the idea, a knob and a button located therein to build a support functionally detached from each other, whereby during adjustment of the Knob the button is not adjusted with. The holder is the constructive connection between the knob and the button. The rotary adjustment is by the knob while the button is pressed via the separate button. For centric illumination with simultaneous centric contacting of the button provides flexible switch plunger with a central passage around which the contacts are preferably circular are attached. The light necessary for illumination can be through the Implementation be initiated in the key. So is a counterpart of the knob on the Holder movably mounted while the key is secured against rotation with the holder. in this connection the advantage is that the key is not specially aligned to a base or circuit board must be because the turntable is executable as a compact item. For a fixation the turntable in a panel this can also be done via the bracket.

Die Halterung kann aber auch fest am Gegenstück des Drehknopfes im Drehschalter angebracht oder Bestandteil des Gegenstückes sein.The holder can also be fixed to the counterpart of the knob in the rotary switch or part of the counterpart.

Die Übertragung der Drehmomente erfolgt direkt oder indirekt, wobei für die direkte Übertragung am Gegenstück des Drehknopfes eine Schichtplatte angebracht ist, während für einer indirekten Übertragung am Gegenstück eine Rundumverzahnung vorgesehen ist, so daß die Drehübertragung auf ein elektronisches Bauelement außermittig erfolgt.The transmission of the torques takes place directly or indirectly, whereby for the direct transmission on the counterpart of the knob a laminated plate is mounted while for a Indirect transmission on the counterpart a Rundumverzahnung is provided, so that the Rotational transfer to an electronic component takes place off-center.

Die Vorteile der vorgeschlagenen Lösung liegen darin, daß neben der Beibehaltung der horizontalen Lage der Taste und der Tastensymbolik eine zentrische, homogene Ausleuchtung der Tastensymbolik und eine zentrische Kontaktierung unterhalb der Taste unabhängig der Drehverstellung des Drehknopfes des Drehstellers oder Drehschalters erfolgt.The advantages of the proposed solution are that in addition to maintaining the horizontal Location of the button and the key symbolic a centric, homogeneous illumination of the Button symbolism and a centric contact below the button independent of the rotary adjustment the knob of the turntable or rotary switch takes place.
