Die DE 20 16 992 A zeigt einen elektrischen Drehschalter einem zwischen zwei Statorteilen gelagerten Drehschaltglied, das mindestens einen als Kontaktkugel ausgestalteten Schaltkontakt zur Beaufschlagung von den Statorteilen zugeordneten Schaltkontaktbahnen aufweist, wobei das Drehschaltglied mit einem Betätigungselement gekoppelt ist und mit Mitteln zur Bestimmung von Schaltstellungen zusammenwirkt, die zum einen der in Richtung des einen Statorteils weisenden Stirnseite des Drehschaltgliedes und zum anderen dem Statorteil zugeordnet sind.

Schließlich beschreibt die DE 101 23 536 C1 eine Bedieneinrichtung für einen elektrischen Schalter mit einem teilweise versenkbaren Druckknopf.Finally, DE 101 23 536 C1 describes an operating device for an electrical switch with a partially retractable push button.

Es ist Aufgabe der Erfindung, einen Drehschalter der eingangs genannten Art zu schaffen, der bei einem einfachen Aufbau einen geringen Einbauraum benötigt.It is an object of the invention to provide a rotary switch of the type mentioned, which requires a small installation space with a simple structure.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass die Mittel zur Bestimmung der Schaltstellungen zum einen der in Richtung des Sockels weisenden Stirnseite des Drehschaltgliedes und zum anderen dem Sockel zugeordnet sind, wobei eine in einem ersten Dom des Drehschaltgliedes druckfederbelastete Rasthülse vorgesehen ist, die mit mindestens einer sockelseitigen Einbuchtung oder Auflaufschräge zusammenwirkt und das Betätigungselement derart axial verschiebbar gelagert ist, dass es in der unteren Endlage bündig mit einer Oberkante des Gehäuses abschließt.According to the invention, the object is achieved in that the means for determining the switching positions are assigned to one facing in the direction of the base end side of the rotary switching element and the other the base, wherein in a first dome of the rotary switching element spring-loaded detent sleeve is provided with at least one cooperates socket-side recess or ramp and the actuator is mounted axially displaceable so that it is flush in the lower end position with an upper edge of the housing.

Aufgrund der axialen Ausrichtung der Mittel zur Bestimmung der Schaltstellungen des Drehschalters im Bereich des Drehschaltgliedes erfordert der Drehschalter einen lediglich geringen Einbauraum, der im Wesentlichen durch die Dimensionierung des Drehschaltgliedes bestimmt wird. Aufgrund der unterschiedlichen Ausgestaltung des Sockels, nämlich zum einen mit Einbuchtungen und zum anderen mit Auflaufschrägen, können mit identisch ausgeführten Drehschaltgliedern entweder gerastete Drehschalter oder getastete Drehschalter gefertigt werden. Hierbei ergibt die Anzahl der sockelseitigen Einbuchtungen die Anzahl der Schaltstellungen vor. Die Auflaufschräge des getasteten Drehschalters vermittelt dem Benutzer ein taktil wahrnehmbares Schaltgefühl. Die Art der axialen Lagerung des Betätigungselementes erfolgt zum einen aus optischen und zum anderen aus funktionalen Gründen. Befindet sich das Betätigungselement in seiner unteren Endlage, ist beispielsweise ein versehentliches Beaufschlagen desselben ausgeschlossen und weitere Betätigungselemente in seiner unmittelbaren Nähe lassen sich problemlos betätigen, da hierfür der erforderliche Freiraum durch das Versenken des Betätigungselementes im Gehäuse geschaffen ist.Due to the axial alignment of the means for determining the switching positions of the rotary switch in the region of the rotary switch member, the rotary switch requires only a small installation space, which is essentially determined by the dimensioning of the rotary switch member. Due to the different design of the base, namely on the one with indentations and on the other with chamfers, can with identically designed rotary switching elements either latched rotary switches or keyed rotary switches are manufactured. Here, the number of socket-side indentations provides the number of switching positions. The ramp of the keyed rotary switch gives the user a tactile perceptible shift feel. The type of axial mounting of the actuating element takes place on the one hand for optical reasons and on the other for functional reasons. The actuator is in its lower end position, for example, an accidental pressurization of the same excluded and other actuators in its immediate vicinity can be operated easily, since this is the required clearance created by the sinking of the actuator in the housing.

Vorzugsweise ist in einem zweiten Dom des Drehschaltgliedes ein Ansatz des Schaltkontaktes druckfederbelastet gehalten. Somit weist das Drehschaltglied bei gewährleisteter Funktionalität einen relativ einfachen Aufbau auf. Die Geometrie des Schaltkontaktes entspricht der eines Abschnittes eines Kreisringes, um bei einer Drehbewegung des Betätigungselementes bzw. des Drehschaltgliedes zugeordnete Schaltkontaktbahnen, beispielsweise eines Stanzgitters oder einer Leiterplatte, zu überbrücken. Die zugeordneten Schaltfunktionen bewirken beispielsweise ein Dimmen einer Instrumentenbeleuchtung eines Kraftfahrzeuges oder einer Höhenverstellung von Kraftfahrzeugscheinwerfern.Preferably, a projection of the switching contact is held by a spring loaded in a second Dom of the rotary switch. Thus, the rotary switch with guaranteed functionality on a relatively simple structure. The geometry of the switching contact corresponds to that of a portion of a circular ring in order to bridge associated with a rotational movement of the actuating element or the rotary switching element switching contact tracks, such as a punched grid or a printed circuit board. The associated switching functions cause, for example, a dimming of an instrument lighting of a motor vehicle or a height adjustment of motor vehicle headlights.

Zur Gewährleistung der Übertragung der Drehbewegung des Betätigungselementes auf das Drehschaltglied mit einfachen Mitteln ist zweckmäßigerweise das Drehschaltglied mit einer Aussparung zur drehfesten Aufnahme des Betätigungselementes versehen.To ensure the transmission of the rotational movement of the actuating element on the rotary switch element with simple means is expediently the rotary switch with a Recess for non-rotatable recording of the actuating element provided.

Zur Bewerkstelligung eines Formschlusses zwischen dem Betätigungselement und dem Drehschaltglied sowie zur Übertragung der beim Verdrehen des Betätigungselementes auftretenden Kräfte ist vorteilhafterweise an das Betätigungselement eine in die Aussparung eingreifende Nase angeformt.To effect a positive connection between the actuating element and the rotary switching member and for transmitting the forces occurring during rotation of the actuating element, a nose engaging in the recess is advantageously formed on the actuating element.

Nach einer vorteilhaften Weiterbildung des Erfindungsgedankens ist das Betätigungselement derart axial verschiebbar gelagert, dass es in der oberen Endlage über die Oberkante des Gehäuses hervorsteht.According to an advantageous development of the inventive concept, the actuating element is mounted so axially displaceable that it protrudes in the upper end position on the upper edge of the housing.

In Ausgestaltung der Erfindung stützt sich das Betätigungselement druckfederbelastet auf dem Sockel ab und weist eine Herzkurve auf, in die ein drehschaltgliedfester Stift eingreift, um das Betätigungselement bei einer Druckbeaufschlagung in der unteren Endlage zu halten und bei einer nochmaligen Druckbeaufschlagung wieder freizugeben. Aufgrund dieser Ausgestaltung ist das Arretieren des Betätigungselementes in seiner unteren Endlage und dessen Freigabe zur Verschiebung in seine obere Endlage durch Druckbeaufschlagungen mit einer geringen Anzahl von Einzelteilen gewährleistet.In an embodiment of the invention, the actuator is supported by spring loaded on the base and has a heart curve, in which a drehschaltgliedfester pin engages to hold the actuator at a pressurization in the lower end position and release again at a further pressurization. Due to this configuration, the locking of the actuating element is ensured in its lower end position and its release for displacement in its upper end position by pressurizing with a small number of items.

Zweckmäßigerweise ist der Stift S-förmig gestaltet, wobei das eine Ende in der Aussparung des Drehschaltgliedes befestigt ist und das andere Ende sich oberhalb des Drehschaltgliedes in die Herzkurve des Betätigungselementes erstreckt. Zweckmäßigerweise ist die Herzkurve in der Nase des Betätigungselementes ausgebildet. Zur zuverlässigen Lagerung bzw. Führung weist bevorzugt das Betätigungselement einen in die Aussparung des Drehschaltgliedes eingreifenden Ansatz auf, dessen Querschnitt als halbkreisförmiger Ring gestaltet ist. Vorzugsweise ist in das Zentrum des Ansatzes eine Druckfeder eingesetzt, die sich zum einen auf einem Steg des Sockels und zum anderen unter Zwischenanordnung einer Kappe an dem Betätigungselement abstützt. Die Kappe schützt das Betätigungselement vor einer Beschädigung durch die Druckfeder.Conveniently, the pin is S-shaped, with one end secured in the recess of the rotary switch member and the other end extending above the rotary switch member into the cardiac cam of the actuator. Conveniently, the heart curve is formed in the nose of the actuating element. For reliable storage or guidance, the actuating element preferably has an engaging into the recess of the rotary switching element approach, whose cross-section is designed as a semicircular ring. Preferably, in the center of the approach, a compression spring is used, which is supported on the one hand on a web of the base and on the other with the interposition of a cap on the actuating element. The cap protects the actuator from damage by the compression spring.

Um der Kappe eine weitere Funktion zuzuordnen, ist vorzugsweise die Kappe als Lichtleiter zur Hinterleuchtung eines Symbols des Betätigungselementes ausgeführt. Die erforderliche Lichtquelle kann beispielsweise dem Sockel zugeordnet sein.In order to assign the cap a further function, the cap is preferably designed as a light guide for backlighting a symbol of the actuating element. The required light source may for example be assigned to the socket.

Vorteilhafterweise taucht der Ansatz des Betätigungselementes in dessen unterer Endlage in eine Ausnehmung des Sockels ein, um eine Verdrehung des Betätigungselementes zu blockieren. Sonach ist der Verdrehschutz des Betätigungselementes mit einfachen Mitteln ohne zusätzliche Bauteile realisiert.Advantageously, the approach of the actuating element immersed in its lower end position in a recess of the base in order to block a rotation of the actuating element. Sonach the Verdrehschutz the actuating element is realized by simple means without additional components.

Die erforderliche Lichtstrahlung wird von auf dem Sockel 1 angeordneten Leuchtelementen 30 ausgesandt.The switch unit comprises a base 1 of a housing, the switching contact tracks 2 are associated with a stamped grid, which open into connection contacts for connection to a vehicle electrical system of a motor vehicle. The peeler unit are assigned to a plurality of individual switches, of which two rotary switches 3, 4 are shown, wherein the one rotary switch 3 keyed switching positions and the other rotary switch 4 snapped switch positions occupies. Each of the rotary switches 3, 4 comprises a substantially circular-section-shaped rotary switching member 5, at its peripheral corner points dome 6, 7 are formed and in the center of which an actuating element 8 engages. In the first dome 6 of the rotary switch member 5, a compression spring loaded locking sleeve 9 is provided. In the keyed version of the rotary switch 3, the latching sleeve 9 cooperates with a ramp 10 of the base 1. For the latched switching positions of the other rotary switch 4 a plurality of indentations 11 are provided in a circular path in the base 1, in which 'the locking sleeve 9 comes to the insert. In the second dome 7, a cylindrical projection 12 of a switching contact 13 is held by pressure spring. The switching contact 13 has the shape of a circular ring section and cooperates with the switching contact tracks 2 in the base 1. The actuator 8 is provided with a nose 14 via a Lug 15 rotatably mounted in a recess 16 of the rotary switch member 5, wherein the projection 15 of the actuating element 8 is designed in its cross section as a semicircular ring. In the center of the projection 15, a compression spring 17 is inserted, which is supported on the one hand on a web 18 of the base 1 and on the other with the interposition of a cap 19 on the actuating element 8. For the transmission of rotational movements, a nose 20 is integrally formed on the projection 15 of the actuating element 8, which engages in a corresponding groove 21 of the recess 16 of the rotary switching member 5. In a radially oriented surface 22 of the nose 20 of the actuating element 8, a heart cam 23 is formed, in which engages an end of an S-shaped pin 24 whose other end is fixed in a bore 25 in the groove 21 of the rotary switching member 5. The heart cam 23 causes, in cooperation with the pin 24 in a conventional manner, a locking of the actuating element 8 in a lower end position at a pressurization thereof and a release of the locking at a renewed pressurization of the actuating element 8, after which the actuating element 8 due to the action of the compression spring 17 reaches its upper end position. In the upper end position is a cylindrical cross-section gripping surface 26 of the actuating element 8 protrudes beyond an upper edge of the housing, so that a user of the rotary switch 3, 4 can apply this. The upper end position of the actuating element 8 is limited by an annular shoulder 27 below the gripping surface 26, which comes to rest within the housing on the same. In the lower end position of the actuating element 8, the annular shoulder 27 is located on the associated end face of the rotary switching element 5 and the projection 15 of the actuating element 8 is immersed in a recess 28 of the base 1, which is dimensioned such that a rotation of the actuating element 8 is blocked in its lower end position.
