Definitions
- the invention relates to an electrical switch or button with two large actuation rockers.
- Switches with two rockers are e.g. Common as a series switch or as a double changeover switch.
- switches that are protected against water ingress.
- Such watertight switches are known, but only in the design as a switch, ie with a single rocker switch.
- the invention has for its object to provide a waterproof switch or button with two large rockers.
- the invention has the advantage that the required watertightness is ensured with a single membrane, which covers the entire switching device, and yet two mutually independent switching functions can be carried out.
- Fig. 1 shows a housing 1 for a switching device (e.g. 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 sealing membrane 4 and one of the two pins 6, which on the switch rockers 5 are attached and fastened by means of locking lugs 7.
- the switch rocker 5 and the pin 6 do not have to be made as pluggable parts, as shown, but can also be made from one Part exist.
- the sealing membrane 4 covers the switching device 12 including the rocker switches 5 with the pin 6 and is inserted between the housing 1 and the housing cover 2.
- the actuating rockers 3 each have a fork-shaped bearing 10 (shown in FIG. 2) and two resilient webs 8. With the resilient webs 8, the actuating rockers 3 are snapped onto the pin 6, so that a positive connection between the actuating rocker 3, sealing membrane 4, pin 6 and switch rocker 5 is formed.
- the actuating rockers 3 are also attached with their fork-shaped mounting 10 to the journal 13 (FIG. 2) on 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 switch rocker bearing 5.1, ie behind the switch rocker bearing 5.1.
- 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 webs 8 are arranged in the middle region of the underside of the actuating rocker 3.
- a contact surface 3.1 is formed with a slight increase. A low-friction contact of the actuating rockers 3 is thus achieved.
- Fig. 3 shows the front view of the operating rocker 3, which can be moved about the axis 9.
- a second contact surface 3.2 is provided in the area of the bearing 10 on the outer wall 11 facing the housing cover 2 and shown in FIG. 2.
- the sealing membrane 4 is shown in FIG. 4 in the front view and in FIG. 5 as a section through the plane A-B (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.
- the sealing membrane 4 is made thinner in an inner area 4.3 than in an outer area 4.2.
- the membrane 4 lies between the contact surfaces of the housing 1 and the housing cover 2.
- a bead 4.1 on the edge of the outer region 4.2 guides the membrane 4 into recesses in the housing cover 2.
- Holes 4.4 are also provided in the outer region 4.2, through which screws for fastening the housing cover 2 are guided on the housing 1.
- support surfaces are provided both on the housing 1 and on the housing cover 2, so that water tightness is achieved by pressing the membrane 4 also in the area of the screw bushing.
- the thin-walled inner region 4.3 is designed like a hood with bumps 4.5 corresponding to the shape of the pin 6.
- the hood-shaped inner region 4.3 is designed to be somewhat higher than the height of the rocker switches 5 with pins 6. Only after the actuating rockers 3 have been snapped on does the membrane 4 lie directly against the pin 6 in the region 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.

Abstract
Description
Die Erfindung betrifft einen elektrischen Schalter oder Taster mit zwei großflächigen Betätigungswippen. Schalter mit zwei Betätigungswippen sind z.B. als Serienschalter oder als doppelte Wechselschalter gebräuchlich.The invention relates to an electrical switch or button with two large actuation rockers. Switches with two rockers are e.g. Common as a series switch or as a double changeover switch.
Für einige Anwendungen sind Schalter erforderlich, die gegen Eindringen von Wasser geschützt sind. Solche wasserdichten Schalter sind bekannt, jedoch nur in der Ausführung als Ausschalter, also mit einer einzigen Betätigungswippe.Some applications require switches that are protected against water ingress. Such watertight switches are known, but only in the design as a switch, ie with a single rocker switch.
Der Erfindung liegt die Aufgabe zugrunde, einen wasserdichten Schalter oder Taster mit zwei großflächigen Betätigungswippen anzugeben.The invention has for its object to provide a waterproof switch or button with two large rockers.
Diese Aufgabe wird durch einen Schalter mit den Merkmalen des Anspruchs 1 gelöst. Ausgestaltungen sind in den Unteransprüchen angegeben.This object is achieved by a switch with the features of
Die Erfindung hat den Vorteil, daß mit einer einzigen 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 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 Schalterwippen aufgerastet werden, hat den Vorteil, daß Schaltgeräte aus der sonstigen Serienproduktion verwendet werden können. Bei hohen Stückzahlen kann aber auch die Herstellung von Zapfen und Schalterwippe in einem Teil zweckmäßig sein.The proposed solution with pins which are snapped onto the usual rocker switches has the advantage that switching devices from other series production can be used. For large quantities, the production of pins and rocker switches in one part can also 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 Gehäuse 1 zu einem Schaltgerät (z.B. Serienschalter) 12, von dem nur eine von zwei Schalterwippen 5 dargestellt ist, einen Gehäusedeckel 2, eine der beiden großflächigen Betätigungswippen 3, eine Dichtungsmembrane 4 und einen der beiden Zapfen 6, die auf die Schalterwippen 5 aufgesteckt und mittels Rastnasen 7 befestigt sind. Die Schalterwippe 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
Die Dichtungsmembran 4 deckt das Schaltgerät 12 einschließlich Schalterwippen 5 mit Zapfen 6 ab und ist zwischen Gehäuse 1 und Gehäusedeckel 2 eingelegt.The sealing
Die Betätigungswippen 3 weisen je eine gabelförmige Lagerung 10 (in Fig. 2 dargestellt) und zwei federnde Stege 8 auf. Mit den federnden Stegen 8 werden die Betätigungswippen 3 auf die Zapfen 6 aufgerastet, so daß eine formschlüssige Verbindung zwischen Betätigungswippen 3, Dichtungsmembrane 4, Zapfen 6 und Schalterwippen 5 entsteht. Die Betätigungswippen 3 sind außerdem mit ihrer gabelförmigen Lagerung 10 auf Lagerzapfen 13 (Fig. 2) am Gehäusedeckel 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 Schalterwippenlagerung 5.1, also hinter der Schalterwippenlagerung 5.1.The actuating
Fig. 2 zeigt eine Seitenansicht einer der Betätigungswippen 3, an deren Außenwand 11 die gabelförmige Lagerung 10 angeordnet ist. Die federnden Stege 8 sind im Mittenbereich der Unterseite der Betätigungswippe 3 angeordnet. An dem einer zweiten Betätigungswippe 3 zugekehrten Rand ist mit einer geringen Erhöhung eine Berührungsfläche 3.1 angeformt. Damit wird eine reibungsarme Berührung der Betätigungswippen 3 erreicht.FIG. 2 shows a side view of one of the actuating
Fig. 3 zeigt die Frontansicht der Betätigungswippe 3, die um die Achse 9 bewegt werden kann. Außer der Berührungsfläche 3.1 an der einer zweiten 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 the operating
Die Dichtungsmembrane 4 ist in Fig. 4 in der Frontansicht und in Fig. 5 als Schnitt durch die Ebene 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
Den Fig. 4 und 5 ist zu entnehmen, daß die Dichtungsmembrane 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 Membrane 4 zwischen den-Berührungsflächen des Gehäuses 1 und des Gehäusedeckels 2. Durch einen Wulst 4.1 am Rand des äußeren Bereichs 4.2 wird die Membrane 4 in Aussparungen im Gehäusedeckel 2 geführt. Im äußeren Bereich 4.2 sind außerdem Löcher 4.4 vorgesehen, durch die Schrauben zur Befestigung des Gehäusedeckels 2 auf dem Gehäuse 1 geführt werden. Im Bereich der Löcher 4.4 sind sowohl am Gehäuse 1 als auch am Gehäusedeckel 2 Auflageflächen vorgesehen, so daß durch Pressung der Membrane 4 auch im Bereich der - Schraubendurchführung Wasserdichtigkeit erreicht wird.4 and 5 that the
Der dünnwandige innere Bereich 4.3 ist haubenartig mit Höckern 4.5 entsprechend der Form der Zapfen 6 ausgeführt. Der haubenförmige innere Bereich 4.3 ist etwas höher ausgeführt, als der Höhe der Schalterwippen 5 mit Zapfen 6 entspricht. Erst nach dem Aufschnappen der Betätigungswippen 3 liegt die Membrane 4 im Bereich der Höcker4.5 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 Schalterwippen 5 etwas über. Damit wird ein ausreichender Raum für die Bewegung der Schalterwippen 5 geschaffen. Dies ist der Darstellung in Fig. 1 zu entnehmen.The thin-walled inner region 4.3 is designed like a hood with bumps 4.5 corresponding to the shape of the
