Description

Die Erfindung betrifft einen elektrischen Schalter, insbesondere für ein Kraftfahrzeug, bestehend aus einem Betätigungsorgan, das schwenkbar in einem Gehäuse aufgenommen ist und einem Schaltstößel, der einerseits mit dem Betätigungsorgan und andererseits mit einem auf einer Leiterplatte angeordneten Schaltelement in Wirkverbindung steht.The invention relates to an electrical switch, in particular for a motor vehicle, consisting of an actuating member which is pivotally accommodated in a housing and a switch plunger which is on the one hand connected to the actuating member and on the other hand with a arranged on a circuit board switching element in operative connection.

Die in Kraftfahrzeugen eingesetzten Schalter besitzen in vielen Fällen mehre Funktionen. So werden beispielsweise für das selbstständige Öffnen der Seitenscheiben Schalter eingesetzt, die mit einer Wippfunktion ausgestattet sind und die beispielsweise durch Drücken und Ziehen zu betätigen sind. Wird ein derartiger Schalter zum Beispiel gedrückt, so öffnet sich die Seitenscheibe und wird an diesem Schalter gezogen, so schließt sich die Scheibe wieder. Bekannt sind ebenso Wippschalter, die derart aufgebaut sind, dass auf beide Seiten der Wippe gedrückt werden kann. So öffnet sich beispielsweise bei der Betätigung der ersten Seite der Wippe ein in das Fahrzeug integriertes Schiebedach und bei der Betätigung der zweiten Seite der Wippe schließt sich dieses wieder.The switches used in motor vehicles have many functions in many cases. Thus, for example, for the independent opening of the side windows switches are used, which are equipped with a rocking function and which are to be operated for example by pressing and pulling. If such a switch, for example, pressed, opens the side window and is pulled at this switch, then the disc closes again. Are also known rocker switch, which are constructed such that can be pressed on both sides of the rocker. Thus, for example, when the first side of the rocker is actuated, a sunroof integrated in the vehicle opens and, when the second side of the rocker is actuated, it closes again.

Ein mit einem als Wippe ausgeführten Betätigungsorgan ausgestatteter Schalter ist in der DE 198 45 135 A1 beschrieben. Mittels der Wippe wird ein Schaltkontakt zwischen zwei Festkontakten hin und her geschaltet, so dass entsprechend zwei unterschiedliche Funktionen anwählbar sind. Nachteilig hieran ist der komplexe und damit teure Aufbau des Schalters.An equipped with a designed as a rocker actuator switch is in the DE 198 45 135 A1 described. By means of the rocker a switching contact between two fixed contacts is switched back and forth, so that two different functions can be selected accordingly. The disadvantage of this is the complex and therefore expensive construction of the switch.

In der DE 100 51 171 B4 ist ein Schalter beschrieben, der in einem Gehäuse und in einem elastischen Abstützelement aufgenommen ist. Neben den an den äußeren Enden vorhandenen elastischen Abstützelementen, besitzt die Schaltwippe in der Mitte des Schalters einen Lagerpunkt, über den das Betätigungselement des Schalters kippbar ist. Bei der Betätigung eines Endes des Betätigungsorgans beziehungsweise der Schaltwippe drückt der Bediener gegen die Kraft des elastischen Abstützelementes und die Federkraft des zu betätigenden Schaltelementes. Nach dem Betätigen stellt sich die Schaltwippe selbstständig unter Einwirkung der auf die Schaltwippe einwirkenden elastischen Kräfte wieder in die Ausgangsstellung zurück. An jedem Ende der Schaltwippe ist ein derartiges elastisches Abstützelement sowie mindestens ein Schaltelement auf einem Sockel angeordnet. Durch die Anordnung der Schaltwippe sowie der dazugehörigen Elemente wird für einen derartigen Schalter eine relativ große Einbaufläche benötigt.In the DE 100 51 171 B4 a switch is described which is accommodated in a housing and in an elastic support element. In addition to the existing at the outer ends of the elastic support members, the rocker has in the middle of the switch a bearing point over which the actuating element of the switch is tilted. Upon actuation of one end of the actuating member or the rocker switch, the operator presses against the force of the elastic support element and the spring force of the switching element to be actuated. After pressing the rocker switch automatically returns to the starting position under the action of the forces acting on the rocker switch elastic forces back. At each end of the rocker switch such an elastic support element and at least one switching element is arranged on a pedestal. The arrangement of the rocker switch and the associated elements a relatively large mounting surface is required for such a switch.

Ein gattungsbildender Schalter ist aus der DE 199 55 070 A1 bekannt. Der Schalter besteht aus einem Betätigungsorgan, das als Wippe ausgeführt ist. Die Schaltwippe des Schalters wirkt mittels eines im Gehäuse geführten Schaltstößels auf ein Schaltelement, das auf einer Leiterplatte im Gehäuse des Schalters angeordnet ist. Das Betätigungsorgan ist kippbar im Gehäuse aufgenommen und wirkt je nach Kipprichtung auf einen unterschiedlichen Schaltstößel.A generic switch is from the DE 199 55 070 A1 known. The switch consists of an actuator, which is designed as a rocker. The switching rocker of the switch acts by means of a guided in the housing switching plunger on a switching element which is arranged on a printed circuit board in the housing of the switch. The actuator is tiltably received in the housing and acts depending on the tilting direction on a different switching plunger.

Aufgabe der Erfindung ist es, einen Schalter zu entwickeln, der bei einer Zug- und Druckbewegung am Betätigungsorgan schaltet, der dabei äußerst kompakt aufgebaut ist, der sich gleichzeitig durch einen einfachen konstruktiven Aufbau auszeichnet und der ein sicheres Betätigen der Schaltelemente ermöglicht.The object of the invention is to develop a switch that switches on a pulling and pushing movement on the actuator, which is constructed extremely compact, which is characterized at the same time by a simple structural design and allows safe operation of the switching elements.

Die erfindungsgemäße Aufgabe der Entwicklung eines elektrischen Schalters wird dadurch gelöst, dass auf einer dem Schaltelement gegenüber liegenden Seite der Leiterplatte ein weiteres Schaltelement angeordnet ist und dass der Schaltstößel als eine Schaltgabel ausgeführt ist und dass die Schaltgabel in der Weise um die Leiterplatte herum angeordnet ist, dass die Schaltgabel mit dem ersten und dem weiteren Schaltelement in Wirkverbindung steht. Durch den erfindungsgemäßen Aufbau des elektrischen Schalters ist nun die Möglichkeit geschaffen, die Schaltelemente in einem äußerst kleinen Raum im Schaltergehäuse anzuordnen und somit eine kompakte Bauweise des Schalters zu realisieren. Dabei wird durch die beidseitig der Leiterplatte angeordnete Schaltelemente und der erfindungsgemäß angeordneten Schaltgabel beim Ziehen oder Drücken des Betätigungsorgans jeweils ein Schaltelement betätigt. Es ist somit ein Zug-/Druckschalter entwickelt, der sich durch einen einfachen konstruktiven Aufbau auszeichnet und somit äußerst kostengünstig herzustellen ist. Durch die Anordnung einer Schaltgabel über den Schaltelementen wird bei einer Betätigung der Schaltgabel, die unmittelbar über den Schaltelementen angeordnet ist, auf jeden Fall bei einer Betätigung des Betätigungsorgan ein Schaltelement betätigt. Es ist somit ein sicheres Betätigen des Schalters möglich.The object according to the invention of developing an electrical switch is achieved in that a further switching element is arranged on a side of the printed circuit board opposite the switching element and in that the switching plunger is designed as a shift fork and that the shift fork is arranged in such a way around the printed circuit board, that the shift fork is in operative connection with the first and the further switching element. The inventive construction of the electrical switch, the possibility is now created to arrange the switching elements in an extremely small space in the switch housing and thus to realize a compact design of the switch. In this case, a switching element is actuated by the arranged on both sides of the circuit board switching elements and the shift fork according to the invention when pulling or pushing the actuator. It is thus a pull / push switch developed, which is characterized by a simple structural design and thus is extremely inexpensive to manufacture. By arranging a shift fork on the switching elements, a switching element is actuated in any case upon actuation of the actuating member in an operation of the shift fork, which is arranged directly above the switching elements. It is thus possible to safely operate the switch.

Die Erfindung wird nachfolgend anhand zweier Ausführungsbeispiele näher beschrieben.The invention will be described in more detail with reference to two embodiments.

FIG. 2
a basic arrangement of the switching elements and the rocker switch on a circuit board.

In der Figur 1 ist eine dreidimensionale Zusammenbauzeichnung eines erfindungsgemäßen Schalters 1 dargestellt. Der Schalter 1 besteht hierbei aus dem als Schaltwippe 2 ausgeführten Betätigungsorgan 2, das Kippbar in einem Gehäuse 3 aufgenommen ist. Innerhalb des Gehäuses 3 ist eine Leiterplatte 4 angeordnet, die von einer zweiteiligen Schaltgabel 5, 6 umschlossen ist. Die Schaltgabel 5, 6 besteht dabei aus einem oberen einen Schaltstößel 7 tragenden oberen Schaltgabelelement 5 und einem unteren Schaltgabelelemt 6, wobei die beiden Schaltgabelelemente formschlüssig ineinander steckbar ausgeführt sind. Auf der Leiterplatte 4 sind Schaltelemente 8, 9 auf den gegenüberliegenden Seiten 10, 11 der Leiterplatte 4 angeordnet. Das Gehäuse 3 des Schalters 1 wird auf seiner Unterseite 12 von einem Gehäuseboden 13 verschlossen.In the FIG. 1 a three-dimensional assembly drawing of a switch 1 according to the invention is shown. The switch 1 in this case consists of the running as a rocker switch 2 actuator 2, the tiltable is accommodated in a housing 3. Within the housing 3, a circuit board 4 is arranged, which is enclosed by a two-part shift fork 5, 6. The shift fork 5, 6 consists of an upper shift fork 7 carrying upper shift fork element 5 and a lower Schaltgabelelemt 6, wherein the two shift fork elements are designed to be positively plugged into one another. On the circuit board 4 switching elements 8, 9 on the opposite sides 10, 11 of the circuit board 4 are arranged. The housing 3 of the switch 1 is closed on its underside 12 by a housing bottom 13.

Die Schaltwippe 2 ist im Gehäuse 3 kippbar beziehungsweise schwenkbar aufgenommen. Dabei steht die Schaltwippe 2 mit der Schaltgabel 5, 6 und insbesondere mit dem oberen Schaltgabelelement 5 in Wirkverbindung. Das obere Schaltgabelelement 5 wirkt mittels des Schaltstößels 7 mit der Schaltwippe 2 zusammen. Hierbei ist vorzugsweise eine formschlüssige Verbindung zwischen dem Schaltstößel 7 und der Schaltwippe 2 ausgebildet, damit die Kippbewegung der Schaltwippe 2 beim Betätigen der Schaltwippe 2 von einer Schwenkbewegung in eine Linearbewegung umgewandelt wird. Das obere Schaltgabelelement 5 sitzt unmittelbar mit einem flachen Bereich 14 auf dem Schaltelement 8 auf, so dass durch die Linearbewegung des Schaltstößels 7 das Schaltelement 8 bei einer Betätigung der Schaltwippe 2 in Richtung der Leiterplatte 4 betätigt wird. Das obere Schaltgabelelement 5 steht mit dem unteren Schaltgabelelement 6 in Wirkverbindung. Im zusammengebauten Zustand werden das untere Schaltgabelelement 6 und das obere Schaltgabelelement 5 im Bereich der Nuten 15 des oberen Schaltgabelelementes 5 ineinander geschoben. Hierbei wird eine entsprechend notwendige Verbindung zwischen dem oberen und unteren Schaltgabelelement 5, 6 hergestellt, so dass ein sicheres Schalten des oberen und unteren Schaltelementes 8, 9 gewährleistet ist. Im zusammengebauten Zustand liegt die ebene Fläche 16 des unteren Schaltgabelelementes 6 spielfrei auf dem unteren Schaltelement 9 auf. Eine spielfreie Anordnung der Schaltgabel 5, 6 ist insbesondere dann vorteilhaft, wenn die Federkräfte der Schaltelemente 8, 9 für das Zurückstellen der Schaltwippe 2 in die neutrale Ausgangsposition Verwendung finden.The rocker switch 2 is tiltably or pivotally received in the housing 3. Here, the rocker switch 2 with the shift fork 5, 6 and in particular with the upper shift fork element 5 in operative connection. The upper shift fork element 5 cooperates with the shift rocker 2 by means of the shift plunger 7. Here, a positive connection between the switching plunger 7 and the rocker switch 2 is preferably formed so that the tilting movement of the rocker switch 2 is converted during actuation of the rocker switch 2 from a pivoting movement into a linear movement. The upper shift fork element 5 is seated directly on a flat area 14 on the switching element 8, so that the switching element 8 is actuated by the linear movement of the switching plunger 7 upon actuation of the rocker switch 2 in the direction of the printed circuit board 4. The upper shift fork element 5 is in operative connection with the lower shift fork element 6. In the assembled state, the lower shift fork element 6 and the upper shift fork element 5 are pushed into each other in the region of the grooves 15 of the upper shift fork element 5. Here, a correspondingly necessary connection between the upper and lower shift fork element 5, 6 is made, so that a safe switching of the upper and lower switching element 8, 9 is ensured. In the assembled state, the flat surface 16 of the lower shift fork element 6 is free of play on the lower switching element 9. A play free Arrangement of the shift fork 5, 6 is particularly advantageous if the spring forces of the switching elements 8, 9 are used for returning the rocker switch 2 in the neutral starting position.

Neben den Schaltelementen 8, 9 sind auf der Leiterplatte 4 weitere Bauteile der Steuerschaltung sowie Leuchtmittel 16 anordbar. Auf der der Schaltwippe 2 abgewandten Seite 11 sind neben dem Schaltelement 9 Anschlußkontakte 17 angeordnet. Die Kontakte 17 reichen in eine Buchse beziehungsweise einen Stecker 18, der in diesem Ausführungsbeispiel in den Gehäuseboden 13 integriert ist, hinein.In addition to the switching elements 8, 9 4 further components of the control circuit and lighting means 16 can be arranged on the circuit board. On the side facing away from the rocker switch 2 11 connecting contacts 17 are arranged in addition to the switching element 9. The contacts 17 extend into a socket or a plug 18, which is integrated into the housing bottom 13 in this embodiment.

Wird nun die Schaltwippe 2 betätigt, und zwar in der Weise, dass das obere Schaltgabelelement 5 in Richtung der Leiterplatte 4 bewegt wird, so wird das Schaltelement 8 betätigt beziehungsweise geschaltet. Das untere Schaltgabelelement 9 entfernt sich dabei vom Schaltelement 9, so dass lediglich das Schaltelement 8 kontaktiert wird. Durch die Federkraft des Schaltelementes 8 wird die Schaltwippe 2 wieder in ihre Ausgangsposition zurückbewegt. Hierbei ist es selbstverständlich möglich, auch weitere zur Rückstellung der Schaltwippe benötigte Federelemente neben der Schaltgabel 5, 6 im Gehäuse 3 anzuordnen. Wird nun die Schaltwippe 2 derart gekippt, dass sich die Schaltgabel 5, 6 in Richtung der Schaltwippe 2 bewegt, so wird das Schaltelement 9 kontaktiert, wobei sich das obere Schaltgabelelement 5 von dem Schaltelement 8 entfernt. Erfindungsgemäß ist somit ein fehlerhaftes Bedienen der Schaltelemente 8, 9 ausgeschlossen, da lediglich ein Schaltelement 8, 9 betätigbar ist.If now the rocker switch 2 is actuated, in such a way that the upper shift fork element 5 is moved in the direction of the printed circuit board 4, the switching element 8 is actuated or switched. The lower shift fork element 9 moves away from the switching element 9, so that only the switching element 8 is contacted. By the spring force of the switching element 8, the rocker switch 2 is moved back to its original position. In this case, it is of course also possible to arrange further spring elements required for returning the rocker switch in addition to the shift fork 5, 6 in the housing 3. If now the rocker switch 2 is tilted such that the shift fork 5, 6 moves in the direction of the rocker switch 2, the switching element 9 is contacted, wherein the upper shift fork element 5 is removed from the switching element 8. Thus, according to the invention, erroneous operation of the switching elements 8, 9 is ruled out since only one switching element 8, 9 can be actuated.

In der Figur 2 ist ein weiteres Ausführungsbeispiel einer erfindungsgemäßen Schaltgabel 19, 20 dargestellt, die seitlich über eine Leiterplatte 21 hinweg geschoben ist. Die dargestellten beiden Schaltgabeln 19 und 20 sind seitlich über Aussparungen 22, 23 in der Leiterplatte über die Schaltelemente 24, 25 geschoben. In diesem Ausführungsbeispiel ist die Schaltgabel 19, 20 als u-förmiges einteiliges Bauteil ausgeführt. Das u-förmige Gabelelement greift dabei mit seinem unteren Schenkel 26 auf das untere Schaltelement 24 und der obere Schenkel 27 des u-förmigen Gabelelementes 19 wirkt unmittelbar auf das obere Schaltelement 25. Hierbei ist lediglich eine Gabel 19 mit Bezugszeichen versehen, um die Übersichtlichkeit der Zeichnung zu gewährleisten.In the FIG. 2 is a further embodiment of a shift fork 19, 20 according to the invention shown, which is laterally pushed over a printed circuit board 21 away. The illustrated two shift forks 19 and 20 are pushed laterally over recesses 22, 23 in the circuit board via the switching elements 24, 25. In this embodiment, the shift fork 19, 20 designed as a U-shaped one-piece component. The U-shaped fork element engages with its lower leg 26 on the lower switching element 24 and the upper leg 27 of the U-shaped fork element 19 acts directly on the upper switching element 25. Here, only a fork 19 is provided with reference numerals to the clarity of To ensure drawing.

Um die Haptik am Schalter entsprechend einstellen zu können, ist in diesem Ausführungsbeispiel die Leiterplatte 21 und insbesondere die Schaltelemente 24, 25 mit einer Schaltmatte 28 versehen. Durch die Anordnung der Schaltgabel 19, 20 über der Leiterplatte ist ein konstruktiv einfach aufgebautes u-förmiges Gabelprofil, als ein beidseitig der Leiterplatte 21 wirkender Schaltstößel, realisiert. Durch diesen simplen Aufbau kann ein kompaktes Schalterelement realisiert werden, dass darüber hinaus mit minimalsten konstruktiven Mitteln realisierbar ist.In order to adjust the feel of the switch accordingly, in this embodiment, the circuit board 21 and in particular the switching elements 24, 25 is provided with a switching mat 28. By the arrangement of the shift fork 19, 20 above the circuit board a structurally simple U-shaped fork profile, as acting on both sides of the circuit board 21 switching plunger realized. Due to this simple construction, a compact switch element can be realized, which, moreover, can be realized with minimal constructional means.

An die Schaltgabel 19 sind Schaltstößel 29, 30 angeformt, die an ihrem oberen Ende Verdickungen-31, 32 aufweisen, die formschlüssig in eine Aufnahme in der Schaltwippe eingreifen. Strichpunktiert ist eine Drehachse 33 eines nicht dargestellten Betätigungsorganes dargestellt. Das Betätigungsorgan ist um die Drehachse 33 herum in die Richtungen des Pfeils P1 betätigbar. Diese Drehachse 33 ist ortsfest im Gehäuse aufgenommen, so dass ein um die Drehachse 33 drehbares Betätigungsorgan an den Verdickungen 31, 32 der Schaltstößel 29, 30 eine Zug- oder Druckbewegung ausführt. Durch die kreisrunde Ausformung der Verdickungen 31, 32 wird hierbei die Kipp- oder Schwenkbewegung in eine lineare Bewegung umgewandelt. Hierzu kann beispielsweise in dem Betätigungsorgan zusätzlich eine Führung für die Verdickungen 31, 32 integriert sein. Bei einer Zug- oder Druckbewegung auf die Schaltstößel 29, 30 bewegt sich die Schaltgabel 19 rechtwinkelig zur Leiterplatte 21 in Richtung des Pfeils P2 und betätigt somit die Schaltkontakte 24, 25 des Schalters.On the shift fork 19 switch plunger 29, 30 are formed, which have at their upper end thickening-31, 32 which engage positively in a receptacle in the rocker switch. Dash-dotted an axis of rotation 33 of an actuating member, not shown, is shown. The actuator is actuatable about the axis of rotation 33 in the directions of the arrow P1. This axis of rotation 33 is received stationary in the housing, so that a rotatable about the axis of rotation 33 actuator on the thickening 31, 32 of the switch plunger 29, 30 performs a tensile or compressive movement. By the circular formation of the thickenings 31, 32 in this case the tilting or pivoting movement is converted into a linear movement. For this purpose, for example, in the actuator additionally a guide for the thickening 31, 32 be integrated. In a tensile or compressive movement of the switch plunger 29, 30, the shift fork 19 moves at right angles to the circuit board 21 in the direction of the arrow P2 and thus actuates the switch contacts 24, 25 of the switch.

Anzumerken bleibt hierbei, dass die Schaltgabel 5, 6, 19 und 20 vorzugsweise aus Kunststoff gefertigt werden, wobei ebenso ein Leichtmetall einsetzbar ist. Darüber hinaus ist die Ausbildung der Schaltgabel 5, 6, 19 und 20 nicht auf die dargestellten Ausführungsformen beschränkt, sondern es ist ebenso vorstellbar, die Schaltgabeln 5, 6, 19, 20 auch mehrteilig und aus unterschiedlichen Werkstoffen herzustellen.It should be noted here that the shift fork 5, 6, 19 and 20 are preferably made of plastic, wherein also a light metal is used. In addition, the design of the shift fork 5, 6, 19 and 20 is not limited to the illustrated embodiments, but it is also conceivable, the shift forks 5, 6, 19, 20 also produce multiple parts and made of different materials.
