Description

Die vorliegende Erfindung geht von einem gemäß Oberbegriff des Hauptanspruches konzipierten elektrischen Drucktastenschalter aus.The present invention is based on a designed according to the preamble of the main claim electrical push-button switch.

Üblicherweise können solche elektrischen Drucktastenschalter zum Ein- bzw. Ausschalten der verschiedensten Funktionen von Kraftfahrzeugen, Haushaltsgeräten, Beleuchtungsanlagen usw. Verwendung finden. Bedarfsweise sind solche elektrischen Drucktastenschalter oftmals derart ausgeführt, dass sie sich tastend in verschiedene Funktionsstellungen bringen lassen.Usually, such electric push-button switch for switching on and off of various functions of motor vehicles, household appliances, lighting systems, etc. are used. If necessary, such electric pushbutton switches are often designed so that they can be groped in different working positions.

Durch die DE 198 09 350 C2 ist ein dem Oberbegriff des Hauptanspruches entsprechender elektrischer Drucktastenschalter bekannt geworden. Dieser elektrische Drucktastenschalter weist ein die ortsfesten und die bewegbaren elektrischen Kontaktteile aufnehmendes, aus Kunststoff bestehendes Gehäuse auf, in welchem eine Drucktaste verschieblich geführt ist. Der Drucktaste ist eine Schraubendruckfeder zugeordnet, welche zum einen die für die Rückstellung der Drucktaste notwendigen Rückstellkräfte erzeugt und welche zum anderen unter Zwischenschaltung eines Zwischengliedes mit einem als Kontaktwippe ausgeführten bewegbaren, elektrischen Kontaktteil zusammenwirkt. Zur Realisierung eines solchen Drucktastenschalters sind jedoch vergleichsweise viele Einzelteile notwendig, die über mehrere Kopplungsstellen miteinander in Wirkverbindung stehen und sowohl bei ihrer Herstellung als auch bei ihrer Montage entsprechend hohe Kosten verursachen. Der Betätigungsweg bei einem derart ausgeführten elektrischen Drucktastenschalter ist jedoch vergleichsweise groß.By the DE 198 09 350 C2 has become known to the preamble of the main claim electrical pushbutton switch. This electric push-button switch has a stationary and the movable electrical contact parts receiving, made of plastic housing, in which a pushbutton is guided in a displaceable manner. The push button is associated with a helical compression spring, which on the one hand generates the restoring forces necessary for the return of the push button and which on the other cooperates with the interposition of an intermediate member with a designed as a contact rocker movable electrical contact part. For the realization of such a push-button switch, however, comparatively many individual parts are necessary, which are in operative connection with one another via a plurality of coupling points and cause correspondingly high costs both during their manufacture and during their assembly. However, the actuation travel in such an executed push-button switch is comparatively large.

US-A-5 508485 offenbart einen anderen Drucktastenschalter nach dem Oberbegriff des Hauptanspruches. US-A-5 508485 discloses another push-button switch according to the preamble of the main claim.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, einen elektrischen Drucktastenschalter zu realisieren, der sich bei besonders kleinem Betätigungsweg einfach auf kostengünstige Art und Weise herstellen lässt und bei dem sowohl die Anzahl der notwendigen Einzelteile, als auch die notwendige Anzahl der Kopplungs- bzw. Wirkverbindungsstellen weitestgehend minimiert sind.The present invention is therefore an object of the invention to realize an electric pushbutton switch, which can be easily produced in a particularly cost-effective manner with a particularly small actuating travel and at Both the number of necessary items, as well as the necessary number of coupling or active joints are minimized as far as possible.

Diese Aufgabe wird durch die im kennzeichnenden Teil des Hauptanspruches angegebenen Merkmale gelöst.This object is achieved by the features stated in the characterizing part of the main claim.

Bei einem solchermaßen konzipierten elektrischen Drucktastenschalter ist besonders vorteilhaft, dass er bei besonders kompaktem Aufbau eine robuste Ausführung aufweist, so dass ein funktionssicherer Einsatz auch in einem rauhen Umfeld ohne weiteres möglich ist.In an electrical pushbutton switch designed in this way, it is particularly advantageous that, in a particularly compact design, it has a robust design, so that a functionally reliable use is readily possible even in a harsh environment.

Wie aus den Figuren hervorgeht, besteht ein solcher elektrischer Drucktastenschalter hauptsächlich aus einem die ortsfesten Kontaktteile und die bewegbaren elektrischen Kontaktteile aufnehmenden, aus Kunststoff bestehenden Gehäuse und zumindest einer verschieblich im Gehäuse geführten Drucktaste 1, welcher eine Schraubendruckfeder 2 zugeordnet ist. Die Schraubendruckfeder 2 ist zum einen für die Erzeugung der zur Rückstellung der Drucktaste 2 notwendigen Rückstellkräfte vorgesehen und wirkt zum anderen mit dem als Kontaktwippe 3 ausgeführten bewegbaren, elektrischen Kontaktteil zusammen.As can be seen from the figures, such an electric pushbutton switch mainly consists of a stationary contact parts and the movable electrical contact parts receiving, made of plastic housing and at least one slidably guided in the housing pushbutton 1, which is associated with a helical compression spring 2. The helical compression spring 2 is provided on the one hand for generating the necessary for resetting the push button 2 restoring forces and acts on the other with the contact rocker 3 as a movable, electrical contact part together.

Wie des weiteren aus den Zeichnungen hervorgeht, besteht das Gehäuse aus einem Grundteil 4 und einem Sockelteil 5. Die ortsfesten Kontaktteile sind als Platinen 6 ausgeführt und in Inserttechnik im Sockelteil 5 festgelegt. Als Vierkantpfosten 7 ausgeführte Anschlusskontakte sind ausgehend von den Platinen 6 nach außen geführt. Andererseits ist die Platinen 6 mit elektronischen Bauteilen 8 bestückt und zum Zusammenwirken mit den an der Kontaktwippe 3 vorhandenen Kontaktkümpeln 9 vorgesehen.As further shown in the drawings, the housing consists of a base 4 and a base part 5. The stationary contact parts are designed as boards 6 and set in insert technology in the base part 5. As a square post 7 running connection contacts are outgoing from the boards 6 to the outside. On the other hand, the boards 6 are equipped with electronic components 8 and provided for cooperation with existing on the contact rocker 3 Kontaktkümpeln 9.

Wie des weiteren aus den Figuren hervorgeht, ist im Bereich der Drehachse X ein als Lager für die als Schraubendruckfeder 2 vorgesehener Haltedom 10 und eine für das Zusammenwirken mit einem Betätigungselement 11 vorgesehene Steuerkurve 12 einstückig an die Kontaktwippe 3 angeformt. Der Haltedom 10 ist dabei ringförmig ausgeführt und die Steuerkurve 12 weist eine W-förmige Ausbildung auf. Sowohl der Haltedom 10, als auch die Steuerkurve 12 stehen in Richtung auf die Drucktaste 1 von der oberen Rahmenfläche der rahmenartig ausgebildeten Kontaktwippe 3 ab. Von der unteren Rahmenfläche der rahmenartig ausgebildeten Kontaktwippe 3 stehen die Kontaktkümpel 9 in Richtung des Sockelteils 5 ab. Zur Bildung der Drehachse X ist an eine Seite der rahmenartigen Kontaktwippe 3 ein Achsstummel 13 angeformt. Die andere mit dem Haltedom 10 versehene Seite der Kontaktwippe 3 liegt mit dem unteren Randbereich des Haltedoms 10 auf einer Kontaktschiene 14 auf. Dabei ist an die Kontaktschiene 14 eine in den Haltedom 10 eintauchende Positioniernase angeformt. Außerdem ist zur sicheren Lagerung der Kontaktwippe 3 an eine Außenwand des Sockelteils 5 eine Lagerschale 15 angeformt. Die Lagerschale 15 und die Kontaktschiene 14 nehmen den Hauptkörper der Kontaktwippe 3 zwischen sich auf, so dass diese schwenkbar im Gehäuse zum Liegen kommen.As is further apparent from the figures, in the region of the axis of rotation X as a bearing for the helical compression spring 2 provided as Haltedom 10 and provided for the interaction with an actuator 11 control cam 12 integrally formed on the contact rocker 3. The Haltedom 10 is designed annular and the control cam 12 has a W-shaped configuration. Both the Haltedom 10, as well as the control cam 12 are in the direction of the push button 1 from the upper frame surface of the frame-like contact rocker 3 from. From the lower frame surface of the frame-like contact rocker 3, the contact 9 are in the direction of the base part 5 from. To form the axis of rotation X is on one side of the frame-like Contact rocker 3 a stub axle 13 is formed. The other side of the contact rocker 3 provided with the retaining dome 10 rests with the lower edge region of the retaining dome 10 on a contact rail 14. In this case, a dipping into the Haltedom 10 positioning lug is formed on the contact rail 14. In addition, for safe storage of the contact rocker 3 to an outer wall of the base part 5, a bearing shell 15 is formed. The bearing shell 15 and the contact rail 14 take the main body of the contact rocker 3 between them, so that they come to rest pivotally in the housing.

Außerdem ist den Figuren entnehmbar, dass der Haltedom 10 für die Schraubendruckfeder 2 in direkter Nähe der Kontaktschiene 14 an die Kontaktwippe 3 angeformt ist. Die Steuerkurve 12 ist hingegen in direkter Nähe des Achsstummels 13 an die Kontaktwippe 3 angeformt. Der Steuerkurve 12 ist ein Betätigungselement 11 zugeordnet, welches mit seinem einen Endbereich 11a direkt mit der Steuerkurve 12 zusammenwirkt und welche mit seinem an deren Endbereich 11 b schwenkbar in einer Aufnahmetasche 16 der Drucktaste 1 gehalten ist. Die Aufnahmetasche 16 ist dabei so ausgeformt, dass das mit seinem anderen Endbereich 11 b in der Drucktaste 1 festgesetzte Betätigungselement 11 elastisch verschwenken kann. Zu diesem Zweck besteht das Betätigungselement 11 aus einem T-förmig gebogenen Blechstanzteil, wobei der der Steuerkurve 12 zugeordnete eine Endbereich 11a der Quersteg ist und der in der Drucktaste 1 festgelegte andere Endbereich 11b das Ende des Längssteges ist. Sowohl der eine Endbereich 11a, als auch der andere Endbereich 11b sind doppelt gelegt ausgeführt. Wie bereits erwähnt, stützt sich die Schraubendruckfeder 2 einerseits an der Kontaktwippe 3 ab und wird von dem daran angeformten Haltedomen 10 sicher gelagert. Andererseits stützt sich die Schraubendruckfeder 2 an der Drucktaste 1 ab, wobei zur sicheren Lagerung der Schraubendruckfeder 2 an die Drucktaste 1 ein Haltestift 17 angeformt ist. Die Schraubendruckfeder 2 kommt dabei in einer weiteren Aufnahmetasche 18 zu liegen, die derart bemessen ist, dass die Schraubendruckfeder 2 bedingt durch die Betätigung zur einen und zur anderen Seite elastisch ausknicken kann.In addition, the figures can be removed that the Haltedom 10 is formed for the helical compression spring 2 in the immediate vicinity of the contact rail 14 to the contact rocker 3. The control cam 12, however, is formed in the immediate vicinity of the stub axle 13 to the contact rocker 3. The control cam 12 is associated with an actuating element 11, which cooperates with its one end portion 11a directly to the control cam 12 and which is held at its end portion 11 b pivotally in a receiving pocket 16 of the push button 1. The receiving pocket 16 is formed so that the fixed with its other end portion 11 b in the push button 1 actuator 11 can pivot elastically. For this purpose, the actuator 11 consists of a T-shaped sheet metal stamped part, wherein the control cam 12 associated with one end portion 11a of the crossbar and the other end portion 11b defined in the pushbutton 1 is the end of the longitudinal web. Both the one end portion 11a, and the other end portion 11b are made double laid. As already mentioned, the helical compression spring 2 is supported, on the one hand, on the contact rocker 3 and is securely mounted by the retaining dome 10 formed thereon. On the other hand, the helical compression spring 2 is supported on the push button 1, wherein for secure storage of the helical compression spring 2 to the push button 1, a retaining pin 17 is formed. The helical compression spring 2 comes to rest in a further receiving pocket 18, which is dimensioned such that the helical compression spring 2 can buckle elastically due to the operation of one side and the other side.

Eines von den auf den Platinen 6 vorhandenen elektronischen Bauteilen 8 ist als LED ausgeführt. Damit das von der LED abgestrahlte Licht möglichst verlustfrei bis zur Betätigungsfläche der Drucktaste 1 geleitet werden kann, ist die Drucktaste 1 trichterförmig ausgeführt. Die kleine Öffnung der Drucktaste 1 ist dabei der LED und die große Öffnung der Drucktaste 1 der Betätigungsfläche zugeordnet.One of the existing on the boards 6 electronic components 8 is designed as an LED. So that the light emitted by the LED light lossless can be passed to the actuating surface of the push button 1, the push button 1 is funnel-shaped. The small opening of the push button 1 is assigned to the LED and the large opening of the push button 1 of the actuating surface.

Wie insbesondere aus den Figuren 3, 4, 5 und 6 hervorgeht, ist der elektrische Drucktastenschalter tastend in zwei verschiedene Funktionsstellungen bringbar. Die erste Funktionsstellung des elektrischen Drucktastenschalters ist in Figur 3 und Figur 4 dargestellt. In seiner ersten Funktionsstellung liegt die Kontaktwippe 3 mit ihrem linken Kontaktkümpel 9 auf der zugeordneten Platine 6 kontaktgebend an. Das Betätigungselement 11 ist mit seinem einen Endbereich 11a der rechten Seite der W-förmigen Steuerkurve 12 zugeordnet. Der rechte Kontaktkümpel 9 ist von seiner zugehörigen Platine 6 abgehoben. Die Schraubendruckfeder 2 weist eine nach links gerichtete, elastische Ausbauchung auf.As in particular from the FIGS. 3, 4 . 5 and 6 shows, the electric push-button switch can be groped in two different functional positions. The first functional position of the electric push-button switch is in FIG. 3 and FIG. 4 shown. In its first functional position, the contact rocker 3 is in contact with its left contact pad 9 on the associated board 6 in contact. The actuator 11 is associated with its one end portion 11 a of the right side of the W-shaped cam 12. The right Kontaktkümpel 9 is lifted from its associated board 6. The helical compression spring 2 has a leftward, elastic bulge.

Wird nun die Drucktaste 1, ausgehend von ihrer in Figur 3 dargestellten Ruheposition niedergedrückt, läuft der eine Endbereich 11 a des Betätigungselementes 11 auf den rechten Bereich der Steuerkurve 12 auf. Bei weiterem Niederdrücken läuft das Betätigungselement 11 den rechten abschüssigen Teil der Steuerkurve 12 entlang, bis es an den rechten Endanschlag der W-förmigen Steuerkurve 12 zu liegen kommt. Bei weiterem Niederdrücken der Drucktaste 1 verschwenkt die Kontaktwippe 3, ausgehend von der in Figur 3 dargestellten Position, in die in Figur 5 dargestellte Position, weil das Betätigungselement 11 die Kontaktwippe 3 mehr und mehr verschwenkt.Now the pushbutton 1, starting from its in FIG. 3 depressed shown rest position, the one end portion 11 a of the actuating element 11 runs on the right portion of the control cam 12. Upon further depression, the actuator 11 runs along the right sloping part of the control cam 12 until it comes to rest on the right end stop of the W-shaped cam 12. Upon further depression of the push button 1 pivots the contact rocker 3, starting from the in FIG. 3 position shown in the FIG. 5 shown position, because the actuator 11, the contact rocker 3 more and more pivots.

Die in Figur 5 und Figur 6 dargestellte zweite Funktionsstellung des elektrischen Drucktastenschalters ist nunmehr erreicht. In seiner zweiten Funktionsstellung liegt die Kontaktwippe 3 mit ihrem rechten Kontaktkümpel 9 auf der zugeordneten Platine 6 kontaktgebend an. Das Betätigungselement 11 ist mit seinem einen Endbereich 11a der linken Seite der W-förmigen Steuerkurve 12 zugeordnet. Der linke Kontaktkümpel 9 ist von seiner zugehörigen Platine 6 abgehoben. Die Schraubendruckfeder 2 weist eine nach rechts gerichtete, elastische Ausbauchung auf.In the FIG. 5 and FIG. 6 shown second functional position of the electric pushbutton switch is now reached. In its second functional position, the contact rocker 3 is contact-contacting with its right contact puddle 9 on the associated board 6. The actuator 11 is associated with its one end portion 11 a of the left side of the W-shaped cam 12. The left contact pocket 9 is lifted off its associated board 6. The helical compression spring 2 has a rightward, elastic bulge.

Auf kostengünstige Art und Weise ist somit ein elektrischer Drucktastenschalter realisiert, bei dem bei besonders kleinem Betätigungsweg sowohl die Anzahl der notwendigen Einzelteile, als auch die notwendige Anzahl der Kopplungs- bzw. Wirkverbindungsstellen weitestgehend minimiert sind. Vorteilhafterweise weist ein solcher elektrischer Drucktastenschalter bei besonders kompaktem Aufbau eine robuste Ausführung auf, so dass ein funktionssicherer Einsatz auch in einem rauhen Umfeld ohne weiteres möglich ist.In a cost effective manner thus an electric pushbutton switch is realized in which both the number of necessary items, as well as the necessary number of coupling or active connection points are minimized as far as possible in a particularly small actuation path. Advantageously, such an electrical pushbutton switch with a particularly compact design to a robust design, so that a reliable operation even in a harsh environment is readily possible.
