Description

Die Erfindung betrifft einen elektrischen Schalter oder Taster der im Oberbegriff des Anspruchs 1 genannten Art.The invention relates to an electrical switch or button of the type mentioned in the preamble of claim 1.

Für gewisse Anwendungen sind Schalter erforderlich, die gegen das Eindringen von Wasser geschützt sind. Wasserdichte Schalter sind sowohl mit einer Betätigungswippe, z.B. in der Ausführung als sogenannter Ausschalter als auch mit zwei Betätigungswippen, z.B. in der Ausführung als sogenannter Serienschalter oder doppelte Wechselschalter bekannt.Switches that are protected against the ingress of water are required for certain applications. Waterproof switches are both equipped with an operating rocker, e.g. in the design as a so-called switch, as well as with two rockers, e.g. known as a so-called series switch or double changeover switch.

Aus der DE-A-2 749 829 ist ein elektrischer Schalter mit zwei großflächigen Betätigungswippen bekannt, dessen im Innenraum eines Gehäuses untergebrachtes Schaltgerät im wesentlichen mittels einer Membran gegenüber dem Eindrigen von Wasser geschützt ist. Ein äußerer Bereich der Membran ist zwischen einem Gehäuseunterteil und einem Behäuseoberteil festgelegt, wohingegen ein innerer Bereich Schaltwippen des Schaltgeräts haubenartig überkragt. Bei diesem bekannten Schalter ist nachteilig, daß die Membran nicht als geschlossene Fläche ausgebildet ist. Die Membran weist, nämlich kreisförmige Löcher auf, welche erst nach erfolgtem Durchgriff von an den Betätigungswippen angeformten und in Versenköffnungen der Schaltwippen eingreifenden Versenkstiften geschlossen werden. Bei dieser Ausgestaltung ist das Eindringen von Feuchtigkeit in das Schaltgerät noch möglich, insbesondere da die Ränder der Membranlöcher und die Außenseiten der Versenkstifte gegeneinander beweglich sind. Auch ist die dortige Membran nicht elastisch ausgebildet. Dies hat zur Folge, daß eine gegenseitige über die Membran wirkende Beeeinflussung der durch die jeweiligen Betätigungswippen ausgelösten Schaltstellungen des Schaltgeräts nicht auszuschließen ist.From DE-A-2 749 829 an electrical switch with two large actuation rockers is known, the switching device housed in the interior of a housing is essentially protected against the ingress of water by means of a membrane. An outer region of the diaphragm is fixed between a lower housing part and an upper housing part, whereas an inner region overhangs the rocker switches of the switching device like a hood. In this known switch it is disadvantageous that the membrane is not designed as a closed surface. The membrane has, in particular, circular holes which are closed only after penetration by countersunk pins formed on the actuating rockers and engaging in the recessed openings of the switching rockers. With this configuration, the penetration of moisture into the switching device is still possible, in particular since the edges of the membrane holes and the outer sides of the countersunk pins can be moved relative to one another. The membrane there is also not elastic. The consequence of this is that mutual influencing of the switching positions of the switching device triggered by the respective actuation rockers cannot be ruled out.

Der Erfindung liegt daher die Aufgabe zugrunde, unter Vermeidung obiger Nachteile einen wasserdichten Schalter oder Taster mit zwei großflächigen Betätigungswippen anzugeben, bei welchem zwei voneinander unabhängige Schaltfunktionen ausgeführt werden können.The invention is therefore based on the object, while avoiding the above disadvantages, of specifying a watertight switch or button with two large actuation rockers, in which two mutually independent switching functions can be carried out.

Diese Aufgabe wird durch einen Schalter mit den Merkmalen das Anspruchs 1 gelöst.This object is achieved by a switch with the features of claim 1.

Ausgestaltungen sind in den Untersprüchen angegeben.Refinements are specified in the subclauses.

Die Erfindung hat den Vorteil, daß mit einer einzigen, eine geschlossen Fläche aufweisenden Membran, die das gesamte Schaltgerät abdeckt, die erforderliche Wasserdichtigkeit gewährleistet ist und trotzdem zwei voneinander unabhängige Schaltfunktionen ausgeführt werden können.The invention has the advantage that the required watertightness is ensured with a single membrane which has a closed surface and covers the entire switching device, and yet two mutually independent switching functions can be carried out.

Die vorgeschlagene Lösung mit Zapfen, die auf die üblichen Schaltwippen aufgerastet werden, hat den Vorteil, daß Schaltgeräte aus der Serienproduktion verwendent werden können. Bei hohen Stückzahlen kann aber auch die Herstellung von Zapfen und Schaltwippe in einem Teil zweckmäßbig sein.The proposed solution with pins that are snapped onto the usual paddle shifters has the advantage that switching devices from series production can be used. For large quantities, however, the production of pins and rocker switch in one part can be useful.

Ein Ausführungsbeispiel ist in der Zeichnung dargestellt und wird nachstehend beschrieben.An embodiment is shown in the drawing and will be described below.

Fig. 1 zeigt ein Gehäuseunterteil 1 für ein Schaltgerät (z.B. Serienschalter) 12, von dem nur eine von zwei Schaltwippen 5 dargestellt ist, einen Gehäusedeckel 2, eine der beiden großflächigen Betätigungswippen 3, eine Membran 4 und einen der beiden Zapfen 6, die auf die Schaltwippen 5 aufgesteckt und mittels Rastnasen 7 befestigt sind. Die Schaltwippe 5 und der Zapfen 6 müssen nicht, wie dargestellt, als zusammensteckbare Teile hergestellt werden, sondern können auch aus einem Teil bestehen.Fig. 1 shows a lower housing part 1 for a switching device (eg series switch) 12, of which only one of two rocker switches 5 is shown, a housing cover 2, one of the two large actuating rockers 3, a membrane 4 and one of the two pins 6, which the shift paddles 5 are attached and fastened by means of locking lugs 7. The rocker switch 5 and the pin 6 do not have to be produced as parts which can be plugged together, as shown, but can also consist of one part.

Die Membran 4 deckt das Schaltgerät 12 einschließlich Schaltwippen 5 nebst Zapfen 6 ab und ist zwischen Gehäuseunterteil 1 und Gehäusedeckel 2 eingelegt.The membrane 4 covers the switching device 12 including the rocker switches 5 together with the pin 6 and is inserted between the lower housing part 1 and the housing cover 2.

Die Betätigungswippen 3 weisen je eine gebelförmige Lagerung 10 (in Fig. 2 dargestellt) und zwei auffedernde Raststege 8 auf. Mittels der auffedernden Raststege 8 werden die Betätigungswippen 3 auf die Zapfen 6 aufgerastet, so daß eine formschlüssige Verbindung zwischen Betätigungswippen 3, Membran 4, Zapfen 6 und Schaltwippen 5 entsteht. Die Betätigungswippen 3 sind außerdem mit ihrer gabelförmigen Lagerung 10 auf Lagerzapfen 13 (Fig. 2) des Gehäusedeckels 2 aufgesteckt. Die am Gehäusedeckel 2 angeformten Lagerzapfen 13 sind in dem Schnittbild der Fig. 1 nicht zu sehen. Sie liegen auf der gleichen theoretischen Achse 9 wie die Schaltwippenlagerung 5.1.The actuating rockers 3 each have a bracket-shaped mounting 10 (shown in FIG. 2) and two resilient locking webs 8. The actuating rockers 3 are snapped onto the pins 6 by means of the spring-loaded latching webs 8, so that a positive connection is created between the actuating rockers 3, membrane 4, pin 6 and switching rockers 5. The actuating rockers 3 are also attached with their fork-shaped bearing 10 to the bearing journal 13 (FIG. 2) of the housing cover 2. The bearing pins 13 formed on the housing cover 2 cannot be seen in the sectional view of FIG. 1. They lie on the same theoretical axis 9 as the shift paddle bearing 5.1.

Fig. 2 zeigt eine Seitenansicht einer der Betätigungswippen 3, an deren Außenwand 11 die gabelförmige Lagerung 10 angeordnet ist. Die auffedernden Raststege 8 sind im Mittenbereich der Unterseite jeder Betätigungswippe 3 angeordnet. An dem der jeweils benachbarten Betätigungswippe 3 zugekehrten Rand ist mit einer geringen Erhöhung eine erste Berührungsfläche 3.1 angeformt. Damit wird eine reibungsarme Berührung der Betätigungswippen 3 erreicht.FIG. 2 shows a side view of one of the actuating rockers 3, on the outer wall 11 of which the fork-shaped bearing 10 is arranged. The resilient locking webs 8 are arranged in the center region of the underside of each actuating rocker 3. On the edge facing the respective adjacent rocker switch 3, a first contact surface 3.1 is formed with a slight increase. A low-friction contact of the actuating rockers 3 is thus achieved.

Fig. 3 zeigt die Frontansicht einer Betätigungswippe 3, die um die Achse 9 bewegt werden kann. Außer der ersten Berührungsfläche 3.1 an der einer benachbarten Berührungswippe 3 zugekehrten Randseite ist auf der dem Gehäusedeckel 2 zugekehrten, in Fig. 2 dargestellten. Außenwand 11 im Bereich der Lagerung 10 eine zweite Berührungsfläche 3.2 vorgesehen.Fig. 3 shows the front view of an operating rocker 3, which can be moved about the axis 9. In addition to the first contact surface 3.1 on the edge side facing an adjacent rocker switch 3, the side facing the housing cover 2 is shown in FIG. 2. A second contact surface 3.2 is provided in the area of the bearing 10 on the outer wall 11.

Die Membran 4 ist in Fig. 4 in der Frontansicht und in Fig. 5 im Schnitt längs der Schnittlinie A-B (siehe Fig. 4) dargestellt. Die Membran 4 muß entsprechend geformt und ausreichend elastisch sein, um die Funktion des Schaltgerätes 12 nicht zu beeinträchtigen.The membrane 4 is in Fig. 4 in the front view and in Fig. 5 in section along the section line AB (see Fig. 4). The membrane 4 must be shaped accordingly and be sufficiently elastic so as not to impair the function of the switching device 12.

Hierdurch wird sichergestellt, daß sich die Membran 4 bei unterschiedlichen Wippstellungen der beiden Betätigungswippen 3 etwas verwinden kann. Eine gegenseitige über die Membran wirkende Beeinflussung der durch die jeweiligen Betätigungswippen 3 ausgelösten Schaltstellungen des Schaltgerätes 12 ist damit weitgehend ausgeschlossen.This ensures that the membrane 4 can twist somewhat with different rocking positions of the two rockers 3. A mutual influencing of the switching positions of the switching device 12 triggered by the respective actuation rockers 3 acting via the membrane is thus largely excluded.

Den Fig. 4 und 5 ist zu entnehmen, daß die Membran 4 in einem inneren Bereich 4.3 dünner ausgeführt ist, als in einem äußeren Bereich 4.2. Mit dem dickeren äußerem Bereich 4.2 liegt die Membran 4 zwischen den Berührungsflächen des Gehäuseunterteils 1 und des Gehäusedeckels 2. Mittels eines Wulstes 4.1 am Rand des äußeren Bereichs 4.2 wird die Membran 4 in Aussparungen des Gehäusedeckels 2 geführt. Im äußeren Bereich 4.2 sind außerdem Löcher 4.4 vorgesehen, durch welche Schrauben zur Befestigung des Gehäusedeckels 2 auf dem Gehäuseunterteil 1 geführt werden. Im Bereich der Löcher 4.4 sind sowohl am Gehäuseunterteil 1 als auch am Gehäusedeckel 2 Auflageflächen vorgeshen, so daß durch Pressung der Membran 4 auch im Bereich der Schraubendurchführung Waserdichtigkeit erreicht wird.4 and 5 that the membrane 4 is made thinner in an inner area 4.3 than in an outer area 4.2. With the thicker outer area 4.2, the membrane 4 lies between the contact surfaces of the lower housing part 1 and the housing cover 2. By means of a bead 4.1 on the edge of the outer area 4.2, the membrane 4 is guided into recesses in the housing cover 2. Holes 4.4 are also provided in the outer area 4.2, through which screws for fastening the housing cover 2 are guided on the lower housing part 1. In the area of the holes 4.4, support surfaces are provided both on the lower housing part 1 and on the housing cover 2, so that water tightness is also achieved in the area of the screw bushing by pressing the membrane 4.

Der dünnwandige innere Bereich 4.3 ist haubenförmig mit Höckern 4.5 entsprechend der Form der Zapfen 6 ausgeführt. Der haubenförmige innre Bereich 4.3 ist etwas höher ausgeführt als der Höhe der Schaltwippen 5 mit Zapfen 6 entspricht. Erst nach dem Aufschnappen der Betätigungswippen 3 liegt die Membran 4 im Bereich der Höcker 4.5 direkt an den Zapfen 6 an. Die obere Kante 4.6 des haubenförmigen inneren Bereichs 4.3 steht dann im Vergleich zur oberen Kante der Schaltwippen 5 etwas über. Damit wird ein ausreichender Raum für die Bewegung der Schaltwippen 5 geschaffen. Dies ist der Darstellung in Fig. 1 zu entnehmen.The thin-walled inner region 4.3 is hood-shaped with cusps 4.5 corresponding to the shape of the pin 6. The hood-shaped inner region 4.3 is designed somewhat higher than the height of the rocker switches 5 with pins 6 corresponds. Only after the actuating rockers 3 have been snapped on does the membrane 4 lie directly against the pin 6 in the area of the cusps 4.5. The upper edge 4.6 of the hood-shaped inner region 4.3 then protrudes somewhat in comparison to the upper edge of the rocker switches 5. This creates sufficient space for the movement of the rocker switches 5. This can be seen in the illustration in FIG. 1.
