Alle für die Erfindung nicht wesentlichen Bauteile des elektrischen Schalters wurden der Einfachheit halber in der Zeichnung nicht dargestellt. Ähnliche Bauteile wurden mit der selben Bezugsziffer versehen.All components not essential to the invention of the electrical switch have been made for convenience Drawing not shown. Similar components were made with the provided with the same reference number.

Wie aus der Zeichnung hervorgeht, besteht ein elektrischer Schalter hauptsächlich aus einem die Schaltkontaktteile und die Festkontaktteile aufnehmenden Gehäuse 1, an welchem ein die Halteeinrichtung beeinflussendes Betätigungsglied beweglich gelagert ist. Zum definierten Erreichen der verschiedenen Schaltstellungen ist das betreffende Betätigungsglied zwei im Gehäuse 1 ortsfest gehaltenen Profilkurveneinrichtungen 2 zugeordnet. Zum definierten Erreichen der Schaltstellungen wirken die Profilkurven der beiden Profilkurveneinrichtungen 2 mit jeweils einem federbelasteten Druckstück 3 zusammen. Außerdem weist das Gehäuse 1 eine Halteeinrichtung auf, die zwei verschieblich im Gehäuse 1 geführte Rastelemente 4 umfaßt.As can be seen from the drawing, there is an electrical one Switch mainly from the switch contact parts and the fixed contact housing 1, on which a Actuator influencing the holding device is movable is stored. For the defined achievement of the different Switch positions, the actuator concerned is two in Housing 1 stationary profile curve devices 2 assigned. To achieve the defined switching positions the profile curves of the two profile curve devices 2 act together with a spring-loaded pressure piece 3. In addition, the housing 1 has a holding device which two locking elements 4 which are slidably guided in the housing 1 includes.

Wie insbesondere aus den Figuren 1 und 5 hervorgeht, ist das der Halteeinrichtung zugeordnete beweglich im Gehäuse 1 gelagerte Betätigungsglied als Dreh-, Zug- und Schubbewegungen übertragender Kombinationsschaltknauf 5 ausgebildet.As can be seen in particular from FIGS. 1 and 5, this is assigned to the holding device movably in the housing 1 mounted actuator as rotating, pulling and pushing movements transmitting combination shift knob 5 formed.

Über eine Drehachse 6 ist der Kombinationsschaltknauf 5 im Gehäuse 1 gelagert. Zum Erreichen seiner verschiedenen Schaltstellungen kann der Kombinationsschaltknauf 5 durch eine Verdrehung zunächst in drei unterschiedliche Schaltstellungen gebracht werden. Durch eine Zug- bzw. Schubbewegung erreicht der Kombinationsschaltknauf 5 darüber hinaus drei verschiedene Schaltebenen A,B,C. Jede Schaltebene A,B,C umfaßt dabei mehrere durch Drehung des Kombinationsschaltknaufes 5 erreichbare Schaltstellungen. Zur Erzeugung der notwendigen Betätigungskräfte kommen die beiden Druckstücke 3 jeweils unter der Wirkung einer Rastfeder 7 an eine der Profilkurven der Profilkurveneinrichtung 2 zur Anlage. Zur Aufnahme der beiden Rastfedern 7 und der beiden Druckstücke 3 sind zwei um 180° versetzt angeordnete Aufnahmekammern in der Drehachse 6 vorhanden, so daß die beiden Druckstücke 3 entgegen der Federkraft der Rastfedern 7 verschieblich gehalten sind. Durch die Profilierung der Profilkurven und die unter Federwirkung stehenden Druckstücke 2 wird der Kombinationsschaltknauf 5 definiert in seinen verschiedenen Schaltstellungen der unterschiedlichen Schaltebenen A,B,C gehalten. Außerdem umfaßt jede der beiden Profilkurveneinrichtungen 2 einen Bereich X, durch den der erhöhte Kraftaufwand realisiert wird, den es beim Betätigen des Kombinationsschaltknauf 5 zu überwinden gilt, soll die Halteeinrichtung in ihre Entriegelungsstellung gebracht werden.The combination shift knob 5 is located on an axis of rotation 6 Housing 1 stored. To achieve its various The combination shift knob 5 can be switched by a First turn into three different switching positions to be brought. Reached by pulling or pushing the combination shift knob 5 also three different ones Switching levels A, B, C. Each switching level A, B, C includes several by turning the combination shift knob 5 achievable switch positions. To generate the necessary Operating forces come the two pressure pieces 3 each under the action of a detent spring 7 to one of the profile curves the profile curve device 2 to the system. To accommodate the two catch springs 7 and the two pressure pieces 3 are two around Receiving chambers offset by 180 ° in the axis of rotation 6 available, so that the two pressure pieces 3 against the Spring force of the detent springs 7 are kept displaceable. By the profiling of the profile curves and the spring action the pressure switch 2 becomes the combination shift knob 5 defined in its various switching positions different switching levels A, B, C. Also includes each of the two profile curve devices 2 has an area X, through which the increased effort is realized to overcome when operating the combination shift knob 5 applies, the holding device should be in its unlocked position to be brought.

Der Bereich X ist so ausgestaltet, daß für den Benutzer ein markanter Kraftanstieg beim Betätigen spürbar wird. Der Kraftanstieg ist so hoch, daß der Kombinationsschaltknauf 5 nur dann in seine Funktionsstellung gebracht wird, wenn dieser bewußt hervorgerufen wird. Dabei ist es notwendig, daß der Kombinationsschaltknauf 5 zunächst durch eine Schubbewegung in die unterste Schaltebene C gebracht und dann um seine Drehachse 6 verdreht wird. Die notwendige Drehbewegung ist dabei der Drehbewegung entgegengesetzt durch die in der untersten Schaltebene C die Schaltstellungen erreichbar sind. Erst wenn sich der Kombinationsschaltknauf 5 durch die vorbeschriebene Bewegungskombination und durch die Überwindung des überhöhten Kraftaufwandes in seiner Funktionsstellung befindet, sind die Rastelemente 4 der Halteeinrichtung in der Entriegelungsstellung. Nur wenn der Kombinationsschaltknauf 5 gegen die auftretende Kraft in seiner Funktionsstellung gehalten wird, kann der elektrische Schalter leicht und einfach aus dem Ausschnitt seines Aufnahmekörpers entfernt werden. Wird der Kombinationsschaltknauf 5 losgelassen, kehren die Rastelemente 4 der Halteeinrichtung automatisch in die Verriegelungsstellung zurück.The area X is designed so that for the user striking increase in force is felt when pressed. Of the Power increase is so high that the combination shift knob 5 is only brought into its functional position if this is deliberately evoked. It is necessary that the Combination shift knob 5 first by pushing in brought the lowest switching level C and then around his Rotation axis 6 is rotated. The necessary rotary motion is doing the rotation opposite to that in the lowest switching level C the switching positions can be reached. Only when the combination shift knob 5 through the prescribed combination of movements and by overcoming the excessive effort in its functional position is located, the locking elements 4 of the holding device in the Unlocked position. Only if the combination shift knob 5 against the force occurring in its functional position the electrical switch can be held easily and simply removed from the cutout of its body will. When the combination shift knob 5 is released, sweep the locking elements 4 of the holding device automatically into the Lock position back.

Die beiden Rastelemente 4 der Halteeinrichtung sind schieberartig ausgebildet und entgegen der Federkraft jeweils einer zugeordneten Schraubendruckfeder 8 verschieblich im Gehäuse gehalten. Durch die schieberartige Ausbildung der Rastelemente 4 ist der elektrische Schalter sicher in seinem Aufnahmekörper gehalten, befindet sich die Halteeinrichtung in ihrer Verriegelungsstellung. Durch eine einfache Zugbewegung kann der elektrische Schalter nicht aus dem Aufnahmekörper entfernt werden, weil die Rastelemente 4 hinter entsprechende Rastkanten des Aufnahmekörpers greifen. An jedes der beiden Rastelemente 4 ist eine Betätigungsnase 9 angeformt, die zum Verschieben der aus Kunststoff hergestellten Rastelemente 4 mit der Übertragungsvorrichtung zusammenwirkt.The two locking elements 4 of the holding device are slider-like and each against the spring force an associated helical compression spring 8 slidably in Housing held. Due to the slide-like design of the Locking elements 4, the electrical switch is safe in its Held receiving body, the holding device is located in their locking position. With a simple pull the electrical switch cannot come out of the receiving body be removed because the locking elements 4 behind corresponding Grip the locking edges of the receiving body. To each of the two Locking elements 4, an actuating lug 9 is formed, which for Moving the locking elements 4 made of plastic cooperates with the transmission device.

Die Übertragungsvorrichtung ist einstückig an die der Halteeinrichtung zugewandte Unterseite des aus Kunststoff hergestellten Kombinationsschaltknauf 5 angeformt. Die topfartige Unterseite des Kombinationsschaltknaufes 5 ist zur Bildung der Übertragungsvorrichtung durch zwei, jeweils einen Absatz 10 bildende Stufen in Richtung auf die Rastelemente 4 erweitert. Zur Betätigung der Rastelemente 4 kommt jeweils eine Absatzkante der beiden Absätze 10 an eine Betätigungsnase 9 eines Rastelementes 4 zur Anlage. Wird der Kombinationsschaltknauf 5 in seine Funktionsstellung gebracht, drücken die Absatzkanten der Absätze 10 durch die Drehbewegung des Kombinationsschaltknaufes 5 die Rastelemente 4 entgegen der Kraft der Schraubendruckfeder 8 in das Gehäuse 1 zurück. Somit geben die Rastelemente 4 den Weg zur Entnahme des elektrischen Schalters aus seinem in der Zeichnung nicht dargestellten Aufnahmekörper frei. The transmission device is in one piece to the Holding device facing the bottom of the plastic Combination shift knob 5 formed. The Pot-like underside of the combination shift knob 5 is for Formation of the transmission device by two, one each Paragraph 10 forming steps in the direction of the locking elements 4th expanded. The locking elements 4 are actuated in each case a heel edge of the two paragraphs 10 to an actuating nose 9 of a locking element 4 to the system. Will the Combination shift knob 5 brought into its functional position, press the heel edges of the heels 10 by the rotary movement of the combination shift knob 5 counter the locking elements 4 the force of the helical compression spring 8 back into the housing 1. Thus, the locking elements 4 give the way to remove the electrical switch from its not in the drawing shown receiving body free.

Wie insbesondere aus der Fig. 2 hervorgeht, kann eine Halteeinrichtung auch durch eine Schubbewegung in seine Entriegelungsstellung gebracht werden.As can be seen in particular from FIG. 2, a Holding device also by a pushing movement into his Unlocked position are brought.

Die an die Übertragungsvorrichtung angeformten Absätze 10 weisen zu diesem Zweck eine in Bezug auf die Verstellrichtung der Übertragungsvorrichtung schräg verlaufende Betätigungsfläche auf. Diese kommen zur Verstellung der Rastelemente 4 an eine schräg zur Verschieberichtung der beiden Rastelemente 4 verlaufende Flanke zur Anlage. Eine Flanke ist dabei jeweils an eine Betätigungsnase 9 der beiden Rastelemente 4 angeformt. Durch eine Schubbewegung der Übertragungsvorrichtung gleiten die schräg verlaufenden Betätigungsflächen und die schräg verlaufenden Flanken aufeinander und ziehen dabei die Rastelemente 4 entgegen der Federkraft der Schraubendruckfedern 8 in das Gehäuse 1 zurück. Somit geben die Rastelemente 4 den Weg zur Entnahme des elektrischen Schalters aus seinem Aufnahmekörper frei.The shoulders 10 formed on the transmission device have one for this purpose in relation to the direction of adjustment the transmission device is inclined Operating area. These come to the adjustment of the Locking elements 4 at an angle to the direction of displacement two locking elements 4 extending edge to the system. A Flank is in each case on an actuating lug 9 of the two Locking elements 4 formed. By pushing the Transmission device slide the sloping ones Actuating surfaces and the sloping flanks on each other and pull the locking elements 4 against Spring force of the helical compression springs 8 back into the housing 1. Thus, the locking elements 4 give the way to remove the electrical switch released from its receiving body.
