Aus der noch nicht vorveröffentlichten deutschen Patentanmeldung mit dem Aktenzeichen 197 22 369 ist bereits ein multifunktionales Einstellelement in Form eines Joysticks mit einem Betätigungsknopf bekannt, wobei der Joystick von einem fest mit der Frontplatte verbundenen Führungsstück gehalten und geführt ist. Der Joystick ist mit einer auf der dem Betätigungsknopf gegenüberliegenden Seite des Führungsstücks befindlichen Sockelplatte verbunden. Der Betätigungsknopf ist auf eine Achse aufgeschnappt, die mit einer Schraube mit der Sockelplatte fest verbunden ist. Durch Verschwenken der Sockelplatte über den Betätigungsknopf erfolgt eine Kontaktierung von auf einer Leiterplatte angeordneten Kontakten.From the not yet published German patent application with the file number 197 22 369 is already a multi-functional adjustment in the form of a joystick with a knob known, the joystick is held and guided by a fixedly connected to the front panel guide piece. The joystick is connected to a base plate located on the side of the guide piece opposite the actuating button. The operating knob is snapped onto an axle which is fixedly connected to the base plate with a screw. By pivoting the base plate via the actuating button contacting takes place arranged on a circuit board contacts.

Die US 4,408,103 zeigt einen Joystick, mit einem Bedienhebel und mit einer mit dem Bedienhebel verbundenen Platte. Ein Verschwenken des Bedienhebels führt dazu, dass die Platte ein Gummistück herunterdrückt und somit eine elektrische Leitung zu einem auf einer Leiterplatte angeordneten Kontakt herstellt.The US 4,408,103 shows a joystick, with an operating lever and with a lever connected to the plate. A pivoting of the operating lever causes the plate presses down a piece of rubber and thus produces an electrical line to a arranged on a circuit board contact.

Die Auslegeschrift DE 1 268 251 zeigt als nächstliegender Stand der Technik ein Schaltgerät mit einer schwenkbaren Schaltstange, bei der ein pyramidenförmiger Gleitkörper an einer Achse gelagert ist. Zwischen dem Gleitkörper und einem Tragkörper ist eine einzige Feder konzentrisch um die Schaltstange herum angeordnet. Die Feder ist mit ihrem einen Ende zentral zum Schwerpunkt in einem Gehäuse fest gelagert und mit ihrem anderen Ende in dem Gleitkörper unverrückbar angeordnet.The layout DE 1 268 251 shows as the closest prior art, a switching device with a pivotable shift rod, in which a pyramid-shaped sliding body is mounted on an axle. Between the slider and a support body, a single spring is disposed concentrically around the shift rod. The spring is fixedly mounted with its one end centrally to the center of gravity in a housing and arranged immovably with its other end in the slider.

Vorteile der ErfindungAdvantages of the invention

Das erfindungsgemäße multifunktionale Bedienelement mit den Merkmalen des Hauptanspruchs hat demgegenüber den Vorteil, dass eine Lagerung auf der dem Betätigungsknopf gegenüberliegenden Seite des Führungsstücks vorgesehen ist, in der die Achse gelagert ist. Auf diese Weise ist keine senkrechte Druckbewegung des Bedienelementes möglich, so daß eine gleichzeitige Kontaktierung von mehr als einem Kontakt verhindert werden kann.The multifunctional operating element according to the invention with the features of the main claim has the advantage that a bearing on the opposite side of the actuating button of the guide piece is provided, in which the Axis is stored. In this way, no vertical pressure movement of the control element is possible, so that a simultaneous contacting of more than one contact can be prevented.

Ein weiterer Vorteil besteht darin, daß eine Rückstellfeder vorgesehen ist, die so mit der Achse zusammenwirkt, daß eine verschwenkte Sockelplatte in eine Ausgangsstellung zurückfedert. Auf diese Weise wird der Bedienkomfort für den Benutzer erhöht, da er das Bedienelement nicht selbst in seine Ausgangsstellung zurückbringen muß. Weiterhin wird verhindert, daß ein Kontakt bzw. Tastschalter zu lange betätigt und auf diese Weise eventuell ein ungewollter Funktionswert eingestellt wird.Another advantage is that a return spring is provided which cooperates with the axis so that a pivoted base plate springs back into an initial position. In this way, the ease of use for the user is increased because he does not have to return the control itself to its original position. Furthermore, it is prevented that a contact or push-button operated too long and possibly an unwanted function value is set in this way.

Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen und Verbesserungen des im Hauptanspruch angegebenen Bedienelementes möglich.The measures listed in the dependent claims advantageous refinements and improvements of the main claim control are possible.

Ein besonderer Vorteil besteht darin, daß der Abstand zwischen der Lagerung und der Sockelplatte einen vorgegebenen Wert überschreitet. Auf diese Weise ist zur Kontaktierung eines Kontaktes mittels der Sockelplatte ein Mindestverschwenkwinkel des Bedienelementes erforderlich, so daß die Positionen des Bedienelementes zur Kontaktierung der einzelnen Kontakte eindeutig voneinander getrennt sind.A particular advantage is that the distance between the bearing and the base plate exceeds a predetermined value. In this way, a Mindestverschwenkwinkel the control element is required for contacting a contact by means of the base plate, so that the positions of the control element for contacting the individual contacts are clearly separated.

Besonders vorteilhaft ist es, daß auf der Leiterplatte Tastschalter angeordnet sind, durch deren Betätigung die Kontaktierung der Kontakte auf der Leiterplatte erfolgt und daß die Tastschalter durch Verschwenken der Sockelplatte betätigbar sind. Auf diese Weise ergibt sich bei der Betätigung eines solchen Tastschalters durch Verschwenken des Bedienelementes ein sog. Schaltknack, durch den der Benutzer über die erfolgreiche Betätigung des entsprechenden Tastschalters informiert wird. Somit wird der Bedienkomfort für den Benutzer erhöht.It is particularly advantageous that tact switches are arranged on the printed circuit board, by the actuation of which the contacting of the contacts takes place on the printed circuit board and that the key switches can be actuated by pivoting the base plate. In this way, results in the operation of such a key switch by pivoting the control element, a so-called. Schaltknack, by the user on the successful operation of the corresponding key switch is informed. Thus, the ease of use for the user is increased.

Ein weiterer Vorteil besteht darin, daß das Führungsstück für jeden Tastschalter einen Führungsschlitz aufweist, in dem die Achse des Bedienelementes führbar ist und daß die Führungsschlitze so im Führungsstück angeordnet sind, daß bei Verschwenken der Sockelplatte der jeweils zugehörige Tastschalter betätigbar ist. Auf diese Weise ist eine definierte und eindeutige Bewegung des Bedienelementes zur Betätigung jeweils eines Kontaktes bzw. Tastschalters möglich, so daß Fehlbedienungen seitens des Benutzers, die zu keiner Kontaktgabe führen, ausgeschlossen werden.Another advantage is that the guide piece for each key switch has a guide slot in which the axis of the control element is feasible and that the guide slots are arranged in the guide piece, that upon pivoting of the base plate of the respective associated key switch can be actuated. In this way, a defined and unambiguous movement of the operating element for actuating a respective contact or key switch is possible, so that incorrect operations on the part of the user, which lead to no contact, are excluded.

Ein weiterer Vorteil besteht darin, daß das Führungsstück im Bereich der Führungsschlitze auf einer dem Betätigungsknopf zugewandten Seite kugelsegmentförmig ausgebildet ist. Auf diese Weise wird eine Auflage für den Betätigungsknopf realisiert, die ebenso wie die Lagerung der Achse verhindert, daß das Bedienelement über den Betätigungsknopf zur Leiterplatte hin gedrückt werden kann und gleichzeitig mehrere Kontakte bzw. Tastschalter durch die Sockelplatte betätigt werden könnten.Another advantage is that the guide piece is formed in the region of the guide slots on a side facing the operating knob spherical segment. In this way, a support for the operating knob is realized, which prevents as well as the storage of the axis that the control element can be pressed on the operating button to the circuit board and at the same time several contacts or push-button could be operated by the base plate.

Ein weiterer Vorteil besteht darin, daß das Führungsstück auf einer dem Betätigungsknopf abgewandten Seite eine Ausnehmung aufweist und daß die Sockelplatte auf einer dem Betätigungsknopf zugewandten Seite kugelsegmentförmig ausgebildet ist. Auf diese Weise läßt sich die Sockelplatte in der Ausnehmung des Führungsstückes führen, so daß die Bedienung für den Benutzer weiter vereinfacht und der Bedienkomfort erhöht wird. Außerdem wird auf diese Weise eine stabilere Lagerung des Bedienelementes in der Frontplatte realisiert.Another advantage is that the guide piece on a side facing away from the actuating knob has a recess and that the base plate is formed on a side facing the operating knob spherical segment. In this way, the base plate can be guided in the recess of the guide piece, so that the operation further simplified for the user and the ease of use is increased. In addition, a more stable storage of the control element in the front panel is realized in this way.

Ein weiterer Vorteil besteht darin, daß der Betätigungsknopf auf die Achse aufgesteckt und an einer dem Führungsstück zugewandten Seite abgeschrägt ist. Auf diese Weise läßt sich der Betätigungsknopf auf einfache Weise auswechseln und ein individuell an die Bedürfnisse und den Geschmack des Benutzers angepaßte Betätigungsknopf auf die Achse aufstecken. Durch die Abschrägung ergibt sich der Vorteil, daß der Betätigungsknopf auch bei Verschwenken des Bedienelementes auf dem Führungsstück gleitend aufliegen kann, so daß die Verschwenkbewegung des Bedienelementes durch das Führungsstück unterstützt und somit der Bedienkomfort erhöht wird.Another advantage is that the operating knob is plugged onto the axis and beveled on a side facing the guide piece. In this way, the operating knob can be replaced in a simple manner and attach an individually adapted to the needs and tastes of the user operating knob on the axle. By chamfering there is the advantage that the operating knob can slide slidably on pivoting of the control element on the guide piece, so that the pivoting movement of the control element supported by the guide piece and thus the ease of use is increased.

Ein weiterer Vorteil besteht darin, daß das Führungsstück als Lichtleitkörper ausgebildet ist und daß eine Lichtquelle zur Beleuchtung des Führungstücks vorgesehen ist. Auf diese Weise wird die Bedienung des Bedienelementes bei Dunkelheit für den Benutzer vereinfacht.Another advantage is that the guide piece is designed as a light guide body and that a light source is provided for illuminating the guide piece. In this way, the operation of the control is simplified in the dark for the user.

Ein weiterer Vorteil besteht darin, daß das Führungsstück durch eine vorzugsweise aufsteckbare Deckelplatte abgedeckt ist, daß die Deckelplatte nicht im Bereich der Führungsschlitze jeweils eine Aussparung aufweist. Auf diese Weise wird der Bedienkomfort für den Benutzer weiter erhöht, da ihm die möglichen Betätigungsrichtungen des Bedienelementes durch die Aussparungen der Deckelplatte bereits angezeigt werden. Dies gilt auch bei Dunkelheit und Beleuchtung des Führungsstückes durch eine Lichtquelle, da die Deckelplatte lichtundurchlässig ausgebildet ist.Another advantage is that the guide piece is covered by a preferably attachable cover plate, that the cover plate does not have in the region of the guide slots in each case a recess. In this way, the ease of use for the user is further increased because the possible directions of actuation of the operating element through the recesses of the cover plate are already displayed. This also applies to darkness and illumination of the guide piece by a light source, since the cover plate is made opaque.

Ein weiterer Vorteil besteht darin, daß der Benutzer die Deckelplatte individuell nach seinen Bedürfnissen und seinem Geschmack wählen kann, da die Deckelplatte auf das Führungsstück aufsteckbar und somit auswechselbar ist.Another advantage is that the user can choose the cover plate individually according to his needs and his taste, since the cover plate is attachable to the guide piece and thus replaceable.

The guide piece 15 protrudes according to Figure 2 or Figure 3 in a first opening 95 on a user interface 105 of the front panel 10 from the inside of the front panel 10. In this case, the guide piece 15 four mutually perpendicular guide slots, which together form a cross-shaped slot. Of the four guide slots, a first guide slot 51 and a second guide slot 52 are shown in Figure 1 for reasons of perspective view. In the region of the guide slots, the guide piece 15 is formed on a segment 5 facing the actuating button 5 spherical segment. This is also clear in the side views of Figures 2 and 3. The guide piece 15 can be covered by a cover plate 85 which can be plugged into the first opening 95, wherein the cover plate 85 can be opaque and has a recess 91, 92, 93, 94 in the region of the guide slots.

Das Bedienelement 1 ist mittels dem Betätigungsknopf 5 in den Führungsschlitzen des Führungsstückes 15 führbar, wobei einem Benutzer die möglichen Betätigungsrichtungen des Bedienelementes 1 durch die Aussparungen 91, 92, 93, 94, die zusammen die Kreuzform der Führungsschlitze vergrößert im Bereich der Bedienoberfläche 105 abbilden, kenntlich gemacht werden. Dabei kann in Verlängerung der Führungsschlitze auf dem Führungsstück 15 innerhalb der Aussparungen 91, 92, 93, 94 jeweils die zugehörige Betätigungsrichtung noch durch eine oder mehrere aufgebrachte Pfeilspitzen verdeutlicht werden. Die Frontplatte 10 ist auf einer Leiterplatte 30 aufgebracht und weist seitlich eine zweite Öffnung 100 auf, über die das Führungsstück 15 über eine Lichtquelle 80 gemäß Figur 3 beleuchtet werden kann. Bei Ausbildung des Führungsstückes 15 als Lichtleitkörper führt dies zu einer entsprechenden Beleuchtung der durch die Aussparungen 91, 92, 93, 94 der Deckelplatte 85 ausgesparten Flächen des Führungsstückes 15, so daß dem Benutzer die möglichen Betätigungsrichtungen auch bei Dunkelheit kenntlich gemacht werden.The operating element 1 can be guided by means of the actuating button 5 in the guide slots of the guide piece 15, wherein a user the possible operating directions of the operating element 1 through the recesses 91, 92, 93, 94, which together enlarge the cross shape of the guide slots in the region of the user interface 105, be identified. In this case, in extension of the guide slots on the guide piece 15 within the recesses 91, 92, 93, 94 respectively, the associated actuating direction can still be illustrated by one or more applied arrowheads. The front panel 10 is mounted on a printed circuit board 30 and laterally has a second opening 100, via which the guide piece 15 can be illuminated via a light source 80 according to FIG. In the formation of the guide piece 15 as a light guide, this leads to a corresponding illumination of the recesses 91, 92, 93, 94 of the cover plate 85 recessed surfaces of the guide piece 15, so that the user the possible operating directions are made even in the dark.

Figur 1 zeigt das Bedienelement 1 in einer Ausgangsstellung. Die Ausgangsstellung ist dadurch gekennzeichnet, daß das Bedienelement 1 nicht in eine der vier möglichen Betätigungsrichtungen verschwenkt ist und sich im Zentrum des durch die Führungsschlitze gebildeten Kreuzes befindet.FIG. 1 shows the operating element 1 in a starting position. The starting position is characterized in that the operating element 1 is not pivoted in one of the four possible directions of actuation and is located in the center of the cross formed by the guide slots.

In Figur 2 ist das in der Frontplatte 10 gelagerte Bedienelement 1 in einer Seitenansicht dargestellt, wobei es sich ebenfalls in der Ausgangsstellung befindet. Der Betätigungsknopf 5 ist dabei auf eine Achse 25 aufgesteckt und an einer dem Führungsstück 15 zugewandten Seite 75 und um die Achse 25 herum abgeschrägt. Das Bedienelement 1 weist auf einer dem Betätigungsknopf 5 gegenüberliegenden Seite des Führungsstücks 15 eine Sockelplatte 20 auf, wobei der Betätigungsknopf 5 und die Sockelplatte 20 über die Achse 25 miteinander fest verbunden sind. Das Führungsstück 15 weist auf einer dem Betätigungsknopf 5 abgewandten Seite eine Ausnehmung 65 auf. Die Sockelplatte 20 ist auf einer dem Betätigungsknopf 5 zugewandten Seite 70 kugelsegmentförmig ausgebildet. Auf einer dem Betätigungsknopf 5 abgewandten Seite weist die Sockelplatte 20 ringförmig um die Achse 25 herum verlaufend eine Abschrägung 110 auf. Die Achse 25 ist auf der dem Betätigungsknopf 5 gegenüberliegenden Seite des Führungsstücks 15 in einer Lagerung 35 der Leiterplatte 30 gelagert. Der Abstand zwischen der Lagerung 35 und der Sockelplatte 20 soll dabei einen vorgegebenen Wert überschreiten.In Figure 2, the mounted in the front panel 10 control element 1 is shown in a side view, wherein it is also in the starting position. The operating knob 5 is attached to an axis 25 and beveled on a guide piece 15 facing side 75 and about the axis 25 around. The operating element 1 has on a side opposite the operating knob 5 side of the guide piece 15, a base plate 20, wherein the actuating button 5 and the base plate 20 are fixedly connected to each other via the axis 25. The guide piece 15 has a recess 65 on a side facing away from the actuating button 5. The base plate 20 is formed on a side facing the operating knob 5 side 70 spherical segment. On a side facing away from the operating knob 5, the base plate 20 has a chamfer 110 extending annularly around the axis 25. The axis 25 is mounted on the actuating button 5 opposite side of the guide piece 15 in a bearing 35 of the circuit board 30. The distance between the bearing 35 and the base plate 20 should exceed a predetermined value.

Die Achse 25 ist in den Führungsschlitzen des Führungsstücks 15 geführt, so daß es je nach Betätigungsrichtung bei der Betätigung des Bedienelementes 1 zu einem Verschwenken der Sockelplatte 20 über den Betätigungsknopf 5 in eine der vier möglichen Betätigungsrichtungen kommt. Jede Betätigungsrichtung bzw. jeder Führungsschlitz ist dabei auf der Leiterplatte 30 einem Kontaktpaar zugeordnet, das durch Betätigung eines Tastschalters kontaktiert bzw. elektrisch leitend miteinander verbunden werden kann. Für jede Betätigungsrichtung ist also ein Tastschalter vorgesehen, der bei entsprechendem Verschwenken des Bedienelementes 1 von der Sockelplatte 20 zur Kontaktierung niedergedrückt wird. Dabei hängt der erforderliche Verschwenkwinkel zum Niederdrücken des entsprechenden Tastschalters vom Abstand zwischen der Lagerung 35 und der Sockelplatte 20 sowie der Abschrägung 110 der Sokkelplatte 20 ab. Von den vier Tastschaltern sind aufgrund der seitlichen Darstellung in Figur 2 und Figur 3 jeweils drei Tastschalter 41, 42, 43 dargestellt.The axis 25 is guided in the guide slots of the guide piece 15, so that it comes depending on the direction of actuation upon actuation of the control element 1 to pivot the base plate 20 via the operating knob 5 in one of the four possible directions of actuation. Each actuation direction or each guide slot is assigned to a contact pair on the printed circuit board 30, which can be contacted by actuation of a pushbutton switch or electrically conductively connected to one another. For each actuation direction, therefore, a push-button switch is provided, which is depressed by a corresponding pivoting of the control element 1 from the base plate 20 for contacting. In this case, the required pivot angle for depressing the corresponding key switch depends on the distance between the bearing 35 and the base plate 20 and the bevel 110 of the Sokkelplatte 20. Of the four keyswitches three push-buttons 41, 42, 43 are shown due to the lateral representation in Figure 2 and Figure 3 respectively.

Die Tastschalter sind dabei ebenfalls auf der Leiterplatte 30 angeordnet. Bei Verschwenken der Sockelplatte 20 über den Betätigungsknopf 5 und die im entsprechenden Führungsschlitz geführte Achse 25 ist somit der jeweils zugehörige Tastschalter betätigbar. Zwischen der Sockelplatte 20 und der Lagerung 35 wird die Achse 25 von einer Rückstellfeder 55 umgriffen, die so mit der Achse 25 zusammenwirkt, daß eine verschwenkte Sockelplatte 20 in die Ausgangsstellung zurückfedert.The key switches are also arranged on the circuit board 30. When pivoting the base plate 20 via the actuating button 5 and the corresponding guide slot guided axis 25 is thus the respective key switch operable. Between the base plate 20 and the bearing 35, the axis 25 is encompassed by a return spring 55 which cooperates with the axis 25 so that a pivoted base plate 20 springs back to the starting position.

In Figur 3 ist das Bedienelement 1 in einer von seiner Ausgangslage verschiedenen, verschwenkten Lage dargestellt. Dabei wird durch einen mit dem Bezugszeichen 115 gekennzeichneten Pfeil eine seitliche Krafteinleitung am Betätigungsknopf 5 dargestellt. Der Betätigungsknopf 5 gleitet dabei mit seiner Abschrägung an seiner dem Führungsstück 15 zugewandten Seite 75 entlang der dem Betätigungsknopf 5 zugewandten, im Bereich der Führungsschlitze kugelsegmentförmig ausgebildeten Seite 60 des Führungsstückes 15. Gleichzeitig ist die Sockelplatte 20 mit ihrer dem Betätigungsknopf 5 zugewandten kugelsegmentförmig ausgebildeten Seite 70 innerhalb der Ausnehmung 65 entlang dem Führungsstück 15 geführt. Dabei führt die seitliche Krafteinleitung am Betätigungsknopf 5 zu einem Verschwenkwinkel des Bedienelementes 1, der zu einem Niederdrücken eines ersten Tastschalters 41 auf der Leiterplatte 30 durch die Sockelplatte 20 führt, wobei ein Schalthub 120 realisiert wird, der zur Kontaktierung des entsprechenden auf der Leiterplatte 30 angeordneten Kontaktflächenpaares über einen Kontakt des entsprechenden ersten Tastschalters 41 führt. Durch die Abschrägung 110 der Sokkelplatte 20 liegt diese beim Niederdrücken des entsprechenden Tastschalters flächig auf dessen Oberfläche auf, so daß keine wesentliche Abnutzung der Sockelplatte 20 und des entsprechenden Tastschalters erfolgt. In der in Figur 3 dargestellten verschwenkten Lage des Bedienelementes 1 ist die Rückstellfeder 55 um einen Federweg 125 seitlich zusammengedrückt, der die für die Rückführung des Bedienelementes 1 in seine Ausgangsstellung erforderliche Rückstellkraft bewirkt.In Figure 3, the control element 1 is shown in a different from its initial position, pivoted position. In this case, a lateral force introduction on the actuating button 5 is represented by an arrow marked with the reference numeral 115. The actuating knob 5 slides with its bevel on its side facing the guide piece 15 side 75 along the actuating button 5 facing, in the region of the guide slots ball segment shaped side 60 of the guide piece 15. At the same time, the base plate 20 with its the operating knob 5 facing spherical segment-shaped side 70th guided within the recess 65 along the guide piece 15. In this case, the lateral introduction of force on the operating knob 5 leads to a pivot angle of the operating element 1, which leads to a depression of a first key switch 41 on the circuit board 30 through the base plate 20, wherein a switching stroke 120 is realized, which arranged for contacting the corresponding on the circuit board 30 Contact surface pair via a contact of the corresponding first key switch 41 leads. Due to the chamfer 110 of the Sokkelplatte 20 this lies on depression of the corresponding key switch area on its surface, so that no significant wear of the base plate 20 and the corresponding key switch takes place. In the illustrated in Figure 3 pivoted position of the control element 1, the return spring 55 is laterally compressed by a spring 125, which causes the required for the return of the control element 1 in its initial position restoring force.

Die Rückstellfeder 55 dient weiterhin dazu, Toleranzschwankungen bei den Abmessungen insbesondere der Führungsschlitze und der Sockelplatte 20 sowie dem Führungsstück 15 und seiner Ausnehmung 65 auszugleichen.The return spring 55 also serves to compensate for tolerance variations in the dimensions of the guide slots and the base plate 20 and the guide piece 15 and its recess 65 in particular.

Die Frontplatte 10 kann Teil eine Bedienfront eines Autoradios sein. Dabei kann bei Ausbildung des Führungsstückes 15 als Lichtleitkörper eine Integration des Führungsstücks 15 in einen Gesamtlichtleiter der Bedienfront des Autoradios erfolgen. Der Betätigungsknopf 5 ist auf die Achse 25 aufsteckbar und die Deckelplatte 85 ist in die erste Öffnung 95 der Frontplatte 10 einsteckbar, so daß der Betätigungsknopf 5 und die Deckelplatte 85 je nach individuellen Bedürfnissen und dem Geschmack des Benutzers ausgewechselt werden können.The front panel 10 may be part of an operating front of a car radio. It can be done in the formation of the guide piece 15 as a light guide an integration of the guide piece 15 in a total light guide the front of the car radio. The operating knob 5 is attachable to the axis 25 and the cover plate 85 is inserted into the first opening 95 of the front panel 10, so that the operating knob 5 and the cover plate 85 can be replaced depending on individual needs and the taste of the user.

Das multifunktionale Bedienelement 1 kann mittels der Betätigung der vier Tastschalter zur Auswahl von Bedienfunktionen, beispielsweise an einem Bedienmenü und/oder zur Einstellung von Funktionswerten einer Bedienfunktion, wie beispielsweise der Lautstärke und der Balance insbesondere bei einem Autoradio verwendet werden. Durch die Multifunktionalität des Bedienelementes 1 läßt sich an der Bedienfront eines solchen Gerätes der Platz für die ansonsten erforderlichen entsprechenden Einzelbedienelemente einsparen und die Übersichtlichkeit für den Benutzer erhöhen.The multifunctional operating element 1 can be used by means of the actuation of the four push-buttons for selecting operating functions, for example on an operating menu and / or for setting functional values of an operating function, such as the volume and the balance, in particular in a car radio. Due to the multifunctionality of the control element 1, the space for the otherwise required corresponding individual control elements can be saved on the front panel of such a device and increase the clarity for the user.

Es können auch mehr oder weniger als vier Betätigungsrichtungen und zugehörige Tastschalter vorgesehen sein, je nach Anforderungen an die durch das Bedienelement 1 zu realisierende Multifunktionalität.It is also possible to provide more or fewer than four actuation directions and associated push-button switches, depending on the requirements of the multifunctionality to be realized by the operating element 1.

Das Bedienelement 1 ist bei allen elektrischen Geräten einsetzbar, bei denen Bedienfunktionen und/oder Funktionswerte von Bedienfunktionen eingestellt werden können.The operating element 1 can be used with all electrical devices in which operating functions and / or function values of operating functions can be set.
