Symmetrisch zu dieser Ebene 8 sind zwei Leiterplatten 9 und 10 parallel zueinander angeordnet. Auf diesen Leiterplatten 9 und 10 sind insbesondere Dioden 11 vorgesehen, die vorzugsweise in einem Diodenkranz die Stirnseiten 12 bzw. 13 des Türöffnerschalters beleuchten und für einen Benutzer die Sichtbarkeit des Schalters verbessern oder ihm den Betriebszustand des Schalters signalisieren. Hierfür ist es natürlich notwendig, dass die Gehäuseelemente 4 und 6 aus einem lichtdurchlässigen Material gefertigt sind. Die Leiterplatten 9 und 10 verfügen über eine um die Achse 14 gelegene Durchbohrung, wobei die Achse 14 sich in einem kleinen Abstand von zum Beispiel 1 Millimeter parallel zur Gehäuselängsachse 7 erstreckt. In diese Öffnung durch die Leiterplatte 9 und 10 hindurch ist eine Hülse 15 eingesetzt, in welcher ein Hebelelement 16 gelagert ist. Dieses Hebelelement 16 ist in Richtung seiner Symmetrieachse 14 verschieblich. Das Hebelelement verfügt an seiner Vorderseite über einen Anschlagkragen 17, der einen Anschlag für die Bewegung des ersten Hebelelementes 16 in den rückwärtigen Schalterbereich bildet.Symmetrical to this plane 8 are two printed circuit boards 9 and 10th arranged parallel to each other. On these circuit boards 9 and 10 diodes 11 are provided in particular, preferably in a diode ring the end faces 12 and 13 of the Door opener switch light and for a user the Improve visibility of the switch or give it the Signal the operating state of the switch.

Anstelle eines Diodenkranzes ist es ebenfalls möglich, Lichtleiter einzusetzen, die ausgehend von einem Leuchtkörper an verschiedene Punkte des Schalters unterhalb eines durchsichtigen Schalterbereichs geführt werden. Dann zeigt das aus ihren Enden austretende Licht dem Benutzer den Betriebszustand des Schalters an. Dabei ist es möglich, an den jeweiligen Lichtaustrittspunkten verschiedene Lichtleiter zu bündeln, die jeweils mit dem Licht einer farblich unterschiedlichen Lichtquelle, z.B. einer Leuchtdiode, beaufschlagt werden.Instead of a diode ring, it is also possible Use optical fiber, starting from a luminous body different points of the switch below a transparent one Switch area are guided. Then that shows off their ends Exiting light the user the operating state of the switch at. It is possible, to the respective Light exit points to bundle different light guides, the each with the light of a different color Light source, e.g. a light emitting diode, are acted upon.

Die Leiterplatten 9 und 10 sind in einem ringförmigen Leiterplattenträger 18 eingelassen, der sich zwischen den und gegen die Gehäuseelemente 4 und 6 abstützt. Dabei liegen sie jeweils auf einer Vielzahl von kleinen Pyramiden 38 und werden beim Aufsetzen der der Gehäuseelemente 4 bzw. 6 entsprechend auf diese aufgepresst. Damit ergibt sich eine in ihrer axialen Lage definierte nach aussen gerichtete Oberfläche der Leiterplatten 9 und 10. Diese genannten Verbindungen werden anschliessend ultraschallgeschweisst, um eine einstückige dichte Schalteinheit zu erhalten. In der Hülse ist eine Öffnung eingelassen, durch die die Anschlusskabel 28 seitlich herausgeführt werden können. The circuit boards 9 and 10 are in an annular Printed circuit board carrier 18 embedded, which is between the and is supported against the housing elements 4 and 6. They are lying each on a variety of small pyramids 38 and become when placing the housing elements 4 and 6 respectively this pressed on. This results in a in their axial position defined outwardly facing surface of the circuit boards. 9 and 10. These named compounds are subsequently ultrasonically welded to a one-piece, tight switching unit to obtain. In the sleeve, an opening is inserted through the connection cables 28 can be led out laterally.

Die Schaltfunktion wird über eine vordere Druckhaube 20 und über eine hintere Druckhaube 30 ausgelöst, die beide vorzugsweise über einen grösseren Durchmesser verfügen. Die Druckhaube 20 und 30 sind mit den Elementen 4 und 6 über eine abdichtende elastische Dichtungsbalg verbunden, die in der Fig. 4 näher dargestellt ist. Die Druckhauben 20 bzw. 30 sind insbesondere entlang ihrer Symmetrieachse 7 in Richtung der Gehäusemitte des Türöffnerschalter verschieblich. In der in der Fig. 1 dargestellten Ruhelage des Schalters befindet sich dabei die Druckhaube 20, die mit dem Druckhaubenträger 22 verbunden ist, in einem Anschlag mit Hilfe des Kragens 21. Das gleiche gilt für die Druckhaube 30, die über einen entsprechenden Anschlag 34 gegen das Element 6 gegen Herausfallen gesichert ist.The switching function is via a front hood 20 and over a rear pressure hood 30 is triggered, both preferably have a larger diameter. The pressure hood 20 and 30 are with the elements 4 and 6 via a sealing elastic sealing bellows connected, the closer in the Fig. 4 is shown. The pressure hoods 20 and 30 are in particular along its axis of symmetry 7 in the direction of the center of the housing Door opener switch displaceable. In the in Fig. 1 shown rest position of the switch is doing the Pressure hood 20, which is connected to the print hood carrier 22, in a stop with the help of the collar 21. The same applies to the pressure hood 30, which has a corresponding stop 34 is secured against falling out of the element 6.

Das zuvor genannte Hebelelement 16 verfügt über ein seitlich von der Achse 14 gegenüber der Achse 7 versetztes Schwenklager 23, welches insbesondere eine Kugelpfanne aufweist, in die ein Vorsprung 24 eines Hebels 25 gelagert ist. Wie durch die parallel zur Gehäuseachse 7 dargestellte weitere Achse 46 zu erkennen ist, ist das Schwenklager 23 in einem seitlichen Abstand gegenüber der Gehäuselängsachse 7 angeordnet, der grösser ist als der Abstand zwischen der Symmetrieachse 14 des Hebelelementes 16 und der Gehäuselängsachse 7. Er beträgt beispielsweise 2,2 Millimeter. Der Hebel 25 verfügt über eine quer verlaufende Achse, in welcher ein Rädchen 26 gelagert ist, welches gegen eine Blattfeder 27 anstösst. Der Hebel 25 verfügt über ein Hebelende 29, welches in einem zum Beispiel acht- bis zehnmal grösseren Abstand von der Gehäuselängsachse 7 gegenüber der weiteren Längsachse 46 angeordnet ist. Das Hebelende 29 befindet sich in Kontakt mit einer federbeaufschlagten Betätigungsnocke 31, die einem mechanischen Schaltorgan 32 zugeordnet ist. The aforementioned lever member 16 has a laterally of the axis 14 relative to the axis 7 offset pivot bearing 23, which in particular has a ball socket into which a Projection 24 of a lever 25 is mounted. How through the parallel to the housing axis 7 shown further axis 46 to recognize is the pivot bearing 23 in a lateral Distance from the housing longitudinal axis 7 is arranged, the is greater than the distance between the axis of symmetry 14 of the Lever element 16 and the housing longitudinal axis 7. He is for example, 2.2 millimeters. The lever 25 has a transverse axis, in which a wheel 26 is mounted, which abuts against a leaf spring 27. The lever 25 has via a lever end 29, which in an example eight- to ten times greater distance from the housing longitudinal axis 7 opposite the further longitudinal axis 46 is arranged. The lever end 29 is in contact with a spring-loaded Actuating cam 31, the mechanical switching element 32nd assigned.

Die Funktion des elektrischen Türöffnerschalters bei einer Betätigung von der Vorderseite aus ist nun in der Fig. 2 dargestellt. Gleiche Merkmale sind in allen Figuren mit den gleichen Bezugszeichen dargestellt. Aus Gründen der Übersichtlichkeit sind jedoch nicht in allen Figuren sämtliche Elemente bezeichnet. Mit dem Pfeil 40 wird die Beaufschlagung der vorderen Druckhaube 20 mit einer Kraft symbolisiert. Durch diese Betätigung wird der Druckhaubenträger 22 in Richtung der Gehäuselängsachse 7 in das Innere des Schalters verschoben. Dabei löst sich insbesondere der mit dem Bezugszeichen 21 erwähnte Anschlag. Mit der Bewegung des Druckhaubenträgers 22 wird ebenfalls die Blattfeder 27 des Druckhaubenträgers 22 verschoben, gegen die das Rädchen 26 im Anschlag ist. Durch den seitlichen Versatz des Schwenklagers 23 rollt das Rädchen 26 auf der Blattfeder 27 ab und entfernt sich aus der Gehäuselängsachse 7. Dies geschieht, da sich das Hebelelement 16 aufgrund des Anschlages 17 nicht weiter in Richtung der Gehäuselängsachse 7 verschieben kann. Durch den dadurch gebildeten Hebelarm zwischen dem Rädchen 26 und dem Schwenklager 23 verkippt der Hebel 25 und das Hebelende 29 betätigt die Betätigungsnocke 31 innerhalb des mechanischen Schaltorgans 32.The function of the electric door opener switch at a Actuation from the front is now in FIG. 2 shown. Same features are in all figures with the the same reference numerals. Because of However, clarity is not all in all figures Called elements. The arrow 40 is the admission the front pressure hood 20 is symbolized with a force. By This operation is the print hood carrier 22 in the direction of Housing longitudinal axis 7 is moved into the interior of the switch. In particular, the one with the reference numeral 21 dissolves mentioned stop. With the movement of the print-hood carrier 22 is also the leaf spring 27 of the print hood carrier 22nd moved against the wheel 26 is in the attack. By the lateral offset of the pivot bearing 23 rolls the wheel 26 on the leaf spring 27 and moves away from the housing longitudinal axis 7. This happens because the lever member 16 due to the Stop 17 not further in the direction of the housing longitudinal axis. 7 can move. By the thus formed lever arm between the wheel 26 and the pivot bearing 23, the lever 25 and tilted the lever end 29 actuates the actuating cam 31 within the mechanical switching element 32.

Diese Funktion tritt unabhängig davon ein, ob die Kraft entsprechend dem Pfeil 40 mittig zur Gehäuselängsachse 7 aufgebracht wird. Bei einer Druckbeaufschlagung im Bereich 41 kann in der Fig. 1 gut erkannt werden, dass dadurch das Rädchen 26 noch etwas schneller in Richtung der Gehäuselängsachse 7 bewegt wird. Dabei bildet der ringförmige Anschlag 37, bzw. bei einer Beaufschlagung der Druckhaube 30 der ringförmige Anschlag 39, auf der gegenüberliegenden Seite zwischen dem vorderen Druckhaubenträger 22 und dem Gehäuseelement 4 den Drehpunkt bei einer solchen seitlichen Druckbeaufschlagung. Das gleiche gilt auch bei einer Kraftbeaufschlagung auf dem gegenüberliegenden Randbereich 42, da die Bewegung der Druckhaube 20 in jedem Fall zu einer axialen Bewegung des Rädchens 26 führt, die ein Verkippen des Hebels 25 zur Folge hat. Es ist also keine zentrale Kraftbeaufschlagung notwendig; es führt auch eine zu einer Verkippung führende Kraftbeaufschlagung der Druckhaube 20 zum Schaltergebnis.This feature occurs regardless of whether the force according to the arrow 40 in the middle of the housing longitudinal axis. 7 is applied. At a pressurization in the range 41 can be well recognized in Fig. 1, that thereby the wheel 26 a little faster in the direction of the housing longitudinal axis. 7 is moved. In this case, the annular stop 37, or at an action on the pressure hood 30 of the annular stop 39, on the opposite side between the front Druckhaubenträger 22 and the housing member 4 at the pivot point such lateral pressurization. The same goes for even with a load on the opposite Edge region 42, since the movement of the pressure hood 20 in any case leads to an axial movement of the wheel 26, the one Tilting the lever 25 results. So it's not central application of force necessary; it also leads to one a tilting leading force application of the pressure hood 20th to the switch result.

Unter Bezugnahme auf die Fig. 3 wird nun die Betätigung des Türöffnerschalters von der Rückseite aus beschrieben, die durch Kraftbeaufschlagung entsprechend dem Pfeil 50 symbolisiert ist. Dadurch wird die hintere Druckhaube 30 entlang der Gehäuselängsachse 7 in das Innere des Türöffnerschalters verschoben. Diese Bewegung bedingt ein Lösen des hinteren Druckhaubenträgers 33 mit seinem Kragen 34 von dem zugehörigen Anschlag des Elementes 6. Der hintere Druckhaubenträger 33 verfügt analog zum vorderen Druckhaubenträger 22 über eine Blattfeder 35, wobei hier eine weitere Betätigungsnocke 36 anliegt, die ein Vorsprung des ersten Hebelelementes 16 ist. Durch die axiale Verschiebung der Druckhaube 30 wird die Blattfeder 35 und damit über die weitere Betätigungsnocke 36 das erste Hebelelement 16 in seiner Hülse 15 entlang der Achse 46 und damit parallel zur Achse 7 verschoben. Diese Verschiebung führt zu einem Abheben des Kragens 17 des Hebelelementes 16 von der Leiterplatte 9. Da sich die vordere Druckhaube 20 über den Kragen 21 des vorderen Druckhaubenträgers 22 im Anschlag befindet, kann die Blattfeder 25 nicht in axialer Richtung 7 bewegt werden. Dadurch ist auch in diesem Fall das Rädchen 26 in einer Zwangsführung, die durch die axiale Aufwärtsbewegung des Schwenklagers 23 zu einer Kippbewegung des Betätigungsnockens 24 zusammen mit dem Rädchen 26 führt, so dass der Hebel 25 auch in diesem Fall verkippt und mit seinem Hebelende 29 die Betätigungsnocke 31 des mechanischen Schaltorgans 32 betätigt. With reference to FIG. 3, the operation of the Door opener switch described from the back, by Kraftbeaufschlagung corresponding to the arrow 50 is symbolized. Thereby, the rear pressure hood 30 along the Housing longitudinal axis 7 in the interior of the door opener switch postponed. This movement requires a release of the rear Hood carrier 33 with its collar 34 of the associated Stopper of the element 6. The rear pressure hood carrier 33 has analogous to the front hood carrier 22 via a Leaf spring 35, in which case a further actuating cam 36th is present, which is a projection of the first lever member 16. Due to the axial displacement of the pressure hood 30 is the Leaf spring 35 and thus on the further actuating cam 36 the first lever member 16 in its sleeve 15 along the axis 46th and thus shifted parallel to the axis 7. This shift leads to a lifting of the collar 17 of the lever member 16 of the printed circuit board 9. Since the front hood 20 over the Collar 21 of the front hood carrier 22 in the stop is located, the leaf spring 25 is not in the axial direction. 7 to be moved. As a result, in this case, the wheel 26 in a positive guidance, by the axial upward movement of the Swivel bearing 23 to a tilting movement of the actuating cam 24th Together with the wheel 26 leads, so that the lever 25 in tilted this case and with its lever end 29 the Actuating cam 31 of the mechanical switching element 32 is actuated.

Die gleiche Betrachtung gilt bei einer Beaufschlagung der hinteren Druckhaube 30 an den Orten 51 bzw. 52 oder allgemein gesagt am Umkreisrand der Druckhaube. In allen Fällen liegt der gegenüberliegende Anteil des Kragens 34 des hinteren Druckhaubenträgers 33 im Anschlag, so dass eine Verkippung der hinteren Druckhaube 30 trotzdem zu einer axialen Bewegung des ersten Hebelelementes 16 führt, wenn auch mit etwas geringerem Hub. Dies ist jedoch gerade ein Vorteil der dargestellten Konstruktion, da auch geringste Schaltwege aufgrund des Übersetzungsverhältnis des Hebels 25 zu einer sicheren Betätigung des mechanischen Schaltelementes 32 führen.The same consideration applies to an admission of rear pressure hood 30 at locations 51 and 52 or generally said at the perimeter edge of the hood. In all cases, the opposite portion of the collar 34 of the rear Druckhaubenträgers 33 in the attack, so that a tilt of the rear pressure hood 30 anyway to an axial movement of the first lever member 16 leads, albeit with a little less Hub. However, this is just an advantage of the illustrated Construction, since even the smallest switching paths due to Gear ratio of the lever 25 to a safe Operation of the mechanical switching element 32 lead.

Die Fig. 4 schliesslich zeigt einen eingebauten Türöffnerschalter in einer Glastür, so dass die Montageplatte 1 beispielsweise aus Glas besteht. Mit dem Bezugszeichen 53 sind die elektrischen Zuleitungen bezeichnet, die in einem Rahmen 54 der Glasscheibe 1 zu einer Steuerschaltung geführt werden. In der perspektivischen Darstellung ist insbesondere das mechanische Schaltelement 32 zu erkennen, welches über die Betätigungsnocke 31 geschaltet wird. Bei dem Hebel 25 handelt es sich um ein längliches Element, in dem in einem quer verlaufenden Schlitz das Rädchen 26 gelagert ist. In der Fig. 4 ist insbesondere gut der Kragen 34 des hinteren Haubenträger 33 zu erkennen und die vorderen bzw. hinteren Dichtungsbalge 55.Finally, FIG. 4 shows a built-in Door opener switch in a glass door, so that the mounting plate 1 for example, made of glass. With the reference numeral 53 are denotes the electrical leads, which in a frame 54th the glass sheet 1 are guided to a control circuit. In the perspective view is in particular the Mechanical switching element 32 to recognize, which over the Actuating cam 31 is switched. The lever 25 is around an elongated element, in which in a transverse extending slot the wheel 26 is mounted. In Fig. 4 is particularly well the collar 34 of the rear hood support 33rd to recognize and the front and rear sealing bellows 55th

Die Rückstellkraft wird jedoch im wesentlichen ausschliesslich durch die federbetätigte Betätigungsnocke 31 erzeugt, die nach Ende der Beaufschlagung der vorderen oder hinteren Druckhaube 20 oder 30 durch eine Kraft diese Druckhauben 20 oder 30 durch eine Rückführung des Hebels 25 in seine Normallage zurückführt. Dies geschieht, da der Hebel 25 zum einen mit seiner Nocke 24 das Hebelelement 16 mit ihrem Kragen 17 in einen Anschlag mit der Leiterplatte 9 drückt und zum anderen das Rädchen 26 in seine Ruhelage strebt, die die vordere Druckhaube 20 in einen Anschlag mit dem Kragen 21 führt.However, the restoring force is essentially exclusively generated by the spring-actuated actuating cam 31, the after End of loading the front or rear pressure hood 20th or 30 by a force these pressure hoods 20 or 30 by a Returning the lever 25 returns to its normal position. This happens because the lever 25 on the one hand with his cam 24 the Lever 16 with its collar 17 in a stop with the PCB 9 presses and on the other hand, the wheel 26 in his Quiescent strives, the front hood 20 in a stop with the collar 21 leads.

Wie in der Fig. 4 zu erkennen ist, bildet der hintere Mantel 2 die den Schalter abdeckende und ästhetisch zu gestaltende hintere Rosette, die die Glasscheibe 1 zwischen sich und dem Element 4 festhält, wobei auf diesem Element 4 die vordere Rosette 3 eingerastet ist. Entgegen der Darstellung in den Zeichnungen kann der Türöffnerschalter natürlich auch bezüglich der Montageplatte 1 symmetrisch ausgestaltet sein. Im allgemeinen jedoch führt die dargestellte Ausführungsform, bei der die flache Seite mit der Druckhaube 20 nach aussen ausgerichtet ist, zu einer grösseren Betriebssicherheit, da diese Beschädigungsversuchen leichter widersteht.As can be seen in FIG. 4, the rear jacket 2 forms the switch covering and aesthetically designed rear rosette, which holds the glass 1 between itself and the Element 4 holds, on this element 4, the front Rosette 3 is engaged. Contrary to the presentation in the Of course, the door opener switch can also drawings the mounting plate 1 be designed symmetrically. in the However, in general, the illustrated embodiment, at the flat side with the pressure hood 20 to the outside is aligned, to a greater operational safety, since this damage is easier to resist.
