Electric house-wiring switch containing a contact rocker (4) which is pivoted at a stationary contact part (2) and is held in its bistable positions by a spring member (5) and which can be switched over by means of intrinsically elastic contact strikers (9), which are pivoted on it at a symmetrical distance from its pivot and project approximately vertically, by a push-button (15) which engages the free ends of the contact strikers (9) with a switching link (16) and which is subject to the action of a returning force, the contact strikers (9) being constructed with three fingers, being held with a central finger (10) at the edge of a window-like cut-out (14) in the contact rocker (4), being held in a self-clamping manner with the outer fingers (11) at a vertically projecting extension of the contact rocker (4) and being supported with a front edge (11.1) of the outer fingers (11) at the contact rocker (4), characterised in that the free ends of the fingers (10, 11) are provided with extensions (12, 13) which are bent in opposite directions in the form of a roof in such a manner that the apex of the extension (12) of the central finger (10) reaches below the edge of the window-like cut-out (14) and that the apex of the extension (13) of the outer fingers (11) rests under tension against the lateral angles (6) which point towards the pivot.

Description

Elektrischer Installationsschalter mit einer Kontaktwippe, die an einem ortsfesten Kontaktteil schwenkbar gelagert und durch ein Federglied in ihren bistabilen Lagen gehalten ist und die mittels an ihr vom Schwenklager in symmetrischem Abstand schwenkbar gelagerter, etwa senkrecht abstehender, selbstfedernder Schaltstössel durch eine an den freien Enden der Schaltstössel mit einer Schaltkulisse angreifende, unter der Wirkung einer Rückführkraft stehende Drucktaste umschaltbar ist, wobei die Schaltstössel dreifingerig ausgeführt, mit einem mittleren Finger an dem Rand eines fensterartigen Durchbruchs der Kontaktwippe, mit den äusseren Fingern an seinem senkrecht abstehenden Ansatz der Kontaktwippe selbstklemmend gehalten und mit einer Stirnkante der äusseren Finger an der Kontaktwippe abgestützt sind.Electrical installation switch with a contact rocker, which is pivotally mounted on a fixed contact part and is held in its bistable positions by a spring element and which is pivotally mounted on it from the pivot bearing at a symmetrical distance, approximately vertically projecting, self-springing switching plunger by one at the free ends of the switching plunger with a switching gate attacking, under the effect of a return force push button is switchable, the switching plunger is three-fingered, with a middle finger on the edge of a window-like opening of the contact rocker, with the outer fingers on its vertically protruding shoulder of the contact rocker and held with one Front edge of the outer fingers are supported on the contact rocker.

Eine Einrichtung dieser Art ist durch die DE-A Nr. 1925813 bekanntgeworden. Dabei sind für die selbstklemmende Halterung der äusseren Finger an der Kontaktwippe an den Seitenkanten der Kontaktwippe angeschnittene Ansätze herausgebogen, während für die klemmende Halterung des mittleren Fingers die Kontaktwippe einen fensterartigen Durchbruch enthält, aus dem ein in Richtung zur Drucktaste des Schalters schräg angewinkelter Lappen ausgebogen ist, hinter deren vorderen Rand eine dem mittleren Finger angewinkelte Verlängerung schneidenförmig gelagert ist. Die so ausgebildeten Schaltstössel sind äusserstschwierig in ihre Lagerungen an der Kontaktwippe zu montieren. So ist es zunächst erforderlich, für die Einführung der angewinkelten Zunge des mittleren Fingers in den fensterartigen Durchbruch den Schaltstössel in einem Winkel erheblich kleiner als 90° zum Längsbalken der Kontaktwippe zu schwenken. Nach Einführung der angewinkelten Zunge des mittleren Fingers in den fensterartigen Durchbruch und Auflage der Stirnkante der äusseren Finger auf der Kontaktwippe kann dann erst der Schaltstössel in die Gebrauchslage, etwa 90° zur Längsachse der Kontaktwippe geschwenkt werden. Dadurch, dass für die Montage die Schaltstössel gegeneinander gerichtet schwenkbar sein müssen, ist eine Montage des zweiten Schaltstössels durch den bereits eingesetzten ersten Schaltstössel nahezu unmöglich gemacht. Für eine solche Montage müsste der zuerst eingesetzte Schaltstössel in die entgegengesetzte Richtung gedrückt werden, wodurch dann leicht eine Deformierung der drei Finger erfolgen kann und eine zuverlässige Halterung dieses Schaltstössels infolge Überdehnung seiner Federelastizität nicht mehr gewährleistet ist.A device of this type has become known from DE-A No. 1925813. For the self-clamping mounting of the outer fingers on the contact rocker, cut-off approaches are bent out on the side edges of the contact rocker, while for the clamping mounting of the middle finger, the contact rocker contains a window-like opening from which a tab bent at an angle to the pushbutton of the switch is bent out , behind the front edge of which an extension angled to the middle finger is mounted in a cutting shape. The switching plungers designed in this way are extremely difficult to mount in their bearings on the contact rocker. So it is first necessary to pivot the switching plunger at an angle considerably smaller than 90 ° to the longitudinal bar of the contact rocker for the insertion of the angled tongue of the middle finger into the window-like opening. After inserting the angled tongue of the middle finger into the window-like opening and resting the front edge of the outer fingers on the contact rocker, the switching plunger can then be pivoted into the position of use, approximately 90 ° to the longitudinal axis of the contact rocker. Because the switch plungers must be pivotable in opposite directions for the assembly, an assembly of the second switch plunger is made almost impossible by the first switch plunger already used. For such an assembly, the shift plunger that was used first would have to be pressed in the opposite direction, as a result of which the three fingers can easily be deformed and a reliable mounting of this shift plunger is no longer guaranteed as a result of its spring elasticity being stretched.

Aufgabe der Erfindung ist es, die Halterung der Schaltstössel an der Kontaktwippe zu verbessern, derart, dass die Schaltstössel senkrecht zur Kontaktwippe, ihrer Gebrauchslage entsprechend, an die Kontaktwippe montierbar sind. Es soll dabei ermöglicht werden, dass die Schaltstössel an die Kontaktwippe durch maschinelle Montage angebracht werden können. Dabei soll eine zuverlässige Halterung der Schaltstössel an der Kontaktwippe gewährleistet werden, die den Gebrauchsanforderungen vollauf gerecht wird.The object of the invention is to improve the mounting of the switching plunger on the contact rocker such that the switching plunger can be mounted on the contact rocker perpendicular to the contact rocker, according to its position of use. It should be made possible that the switch plunger can be attached to the contact rocker by mechanical assembly. A reliable mounting of the switching plunger on the contact rocker should be ensured, which fully meets the requirements for use.

Erfindungsgemäss wird dies dadurch erreicht, dass die freien Enden der Finger Verlängerungen aufweisen, die gegenläufig dachförmig derart gebogen sind, dass der Scheitelpunkt der Verlängerung des mittleren Fingers den Rand des fensterartigen Durchbruchs untergreift und dass der Scheitelpunkt der Verlängerung der äusseren Finger an seitlichen, gegen das Schenklager gerichteten Anwinkelungen unter Spannung anliegt.According to the invention, this is achieved in that the free ends of the fingers have extensions which are curved in opposite directions in a roof shape in such a way that the apex of the extension of the middle finger engages under the edge of the window-like opening and that the apex of the extension of the outer fingers on the side against the Schenklager directed bends under tension.

Dabei sind der Kontaktwippe an ihren Längsseiten die Anwinkelungen angeformt, die mit zentralen Einschnitten auf dem ortsfesten Kontaktteil das Schwenklager bilden und an deren Längsseiten die äusseren Finger der Schaltstössel anliegen.The contact rockers are molded on their long sides, which form the pivot bearing with central incisions on the fixed contact part and on the long sides of which the outer fingers of the switching plunger rest.

Ein weiteres Merkmal der Erfindung besteht darin, dass die Kontaktwippe eine zentrale, gegen die Drucktaste gerichtete rinnenförmige Abwinkelung aufweist, mit zum Längsbalken der Kontaktwippe senkrechten Wänden, gegen die die äusseren Finger anliegen.Another feature of the invention is that the contact rocker has a central channel-shaped bend directed against the pushbutton, with walls perpendicular to the longitudinal bar of the contact rocker, against which the outer fingers rest.

Ein besonderes Merkmal besteht darin, dass durch die Anlage der äusseren Finger an der senkrechten Wand der rinnenförmigen Abwinkelung und deren Verlängerungsscheitelpunkt an den Längsseiten der seitlichen Anwinkelungen eine Zweipunktauflage der äusseren Finger gebildet ist, die mit der etwa auf deren Mittelsenkrechten liegenden Anlage des mittleren Fingers im fensterartigen Durchbruch eine Dreipunktauflage für den Schaltstössel bilden.A special feature is that by placing the outer fingers on the vertical wall of the channel-shaped bend and extending their apex on the long sides of the side bends, a two-point support of the outer fingers is formed, which is in line with the middle finger lying approximately on their central perpendicular window-like opening form a three-point support for the switching plunger.

Schliesslich ist als die bistabilen Lagen der Kontaktwippe bewirkendes Federglied eine Zugfeder vorgesehen, deren Lagerung an der Kontaktwippe ein zwischen den Schaltstösseln und parallel zu diesen liegender, gegen die Drucktaste gerichteter Ansatz ist, der bei Bildung eines fensterartigen Durchbruchs aus der Kontaktwippe ausgeschert ist.Finally, a tension spring is provided as the spring element causing the bistable positions of the contact rocker, the mounting of which on the contact rocker is an approach between the switching tappets and parallel to it, directed against the pushbutton, which is deflected out of the contact rocker when a window-like opening is formed.

In the drawing, an embodiment of the invention is shown on an enlarged scale. It shows:
  • 1 is a view of a switch,
  • 2 is a plan view of the contact rocker with the switching plungers attached,
  • Fig. 3 is a view of a switching plunger mounted on the contact rocker, and
  • Fig. 4 is a detailed view with a schematic representation of the bearing points of the switching plunger on the contact rocker.

Der Schalter besteht aus dem Gehäuse 1 aus Isolierstoff, an dem ortsfeste Kontaktteile 2 und 3 befestigt sind. Der ortsfeste Kontaktteil 2 trägt auf einem Schwenklager eine Kontaktwippe 4, die mittels einer Zugfeder 5 an diesem schwenkbar gelagert ist. Dazu besitzt die Kontaktwippe 4 an ihren Längsseiten angeformte Anwinkelungen 6, die mit zentralen Einschnitten 7 in Verbindung mit dem ortsfesten Kontaktteil 2 das Schwenklager bilden.The switch consists of the housing 1 made of insulating material, to which fixed contact parts 2 and 3 are attached. The fixed contact part 2 carries a contact rocker 4 on a pivot bearing, which is pivotably mounted on this by means of a tension spring 5. For this purpose, the contact rocker 4 has formed on its long sides bends 6, which form the pivot bearing with central cuts 7 in connection with the fixed contact part 2.

Durch die Zugfeder 5 wird die Kontaktwippe 4 jeweils in ihren bistabilen Lagen zur Kontaktgabe mit den jeweiligen ortsfesten Kontaktteilen 3 gehalten.By means of the tension spring 5, the contact rocker 4 is held in its bistable positions for making contact with the respective stationary contact parts 3.

Für die Umschaltung in die jeweiligen bistabilen Lagen ist die Kontaktwippe 4 mit Schaltstösseln 9 versehen, die an ihr in einem symmetrischen Abstand vom Schwenklager schwenkbar angeordnet sind. Dabei stehen die Schaltstössel 9 in ihrer Ruhelage etwa senkrecht zum Längsbalken der Kontaktwippe 4 und sind an ihren freien Enden durch eine Drucktaste 15 mittels einer Schaltkulisse 16 betätigbar.For the switchover to the respective bistable positions, the contact rocker 4 is provided with switching plungers 9 which are pivotably arranged on it at a symmetrical distance from the pivot bearing. The switching plunger 9 are in their rest position approximately perpendicular to the longitudinal bar of the contact rocker 4 and can be actuated at their free ends by a push button 15 by means of a switching link 16.

Die Schaltstössel 9 sind dreifingerig ausgebildet und sind mit einer Stirnkante 11.1 der äusseren Finger 11 auf der Oberfläche der Kontaktwippe 4 abgestützt. Die Kontaktwippe 4 besitzt eine zentrale gegen die Drucktaste 15 gerichtete rinnenförmige Abwinkelung 17 mit rechtwinkelig zum Längsbalken der Kontaktwippe 4 liegenden Wänden 18, gegen die die äusseren Finger 11 der Schaltstössel 9 von aussen anliegen. Diese äusseren Finger 11 besitzen weiterhin über die Stirnkante 11.1 hinausgehende Verlängerungen 13, die dachförmig gebogen mit ihrem Scheitelpunkt gegen die Anwinkelungen 6 anliegen. Der mittlere Finger 10 der Schaltstössel 9 durchgreift mit einer Verlängerung 12 einen fensterartigen Durchbruch 14 der Kontaktwippe 4 und ist ebenfalls dachförmig, jedoch gegenläufig zu der Dachform der Verlängerungen 13 der äusseren Finger 11 gebogen. Dabei hintergreift der Scheitelpunkt der Verlängerung 12 des mittleren Fingers 10 den Rand der fensterartigen Durchbruchs 14. Die Verlängerungen 12 und 13 des Schaltstössels 9 sind dabei unter Vorspannung an der Kontaktwippe 4 gehalten. Die Stirnkante 11.1 der äusseren Finger 11 bildet in ihrer Einlage in dem durch den Längsbalken der Kontaktwippe 4 und die Wand 18 der rinnenförmigen Abwinkelung 17 gebildeten Winkel ein Schwenklager. Wie insbesondere aus der Fig. 4 ersichtlich, wird durch die Anlage der äusseren Finger 11 an der senkrechten Wand 18 der rinnenförmigen Abwinkelung 17 und dem Scheitelpunkt von deren Verlängerung 13 an den Längsseiten der seitlichen Anwinkelungen 6 eine Zweipunktauflage A-B für diese äusseren Finger 11 gebildet. Etwa auf der Mittelsenkrechten C der Zweipunktauflage A-B befindet sich die Anlage D der Verlängerung 12 des mittleren Fingers 10 im fensterartigen Durchbruch 14 der Kontaktwippe 4. Hierdurch wird eine solide Dreipunktanlage der Schaltstössel 9 an der Kontaktwippe 4 erzielt, wodurch nach jeder Schaltbetätigung der dabei ausschwenkende Schaltstössel 9 stets in die senkrechte Ausgangslage an der Kontaktwippe 4 selbsttätig zurückführbar ist.The switching plungers 9 are designed with three fingers and are supported on the surface of the contact rocker 4 by a front edge 11.1 of the outer fingers 11. The contact rocker 4 has a central channel-shaped bend 17 directed against the push button 15 with walls 18 lying at right angles to the longitudinal bar of the contact rocker 4, against which the outer fingers 11 of the switching plunger 9 rest from the outside. These outer fingers 11 also have extensions 13 which extend beyond the end edge 11.1 and which are bent in a roof-shaped manner with their apex against the angles 6. The middle finger 10 of the switching plunger 9 passes through a window-like opening 14 of the contact rocker 4 with an extension 12 and is also roof-shaped, but curved in the opposite direction to the roof shape of the extensions 13 of the outer fingers 11. The apex of the extension 12 of the middle finger 10 engages behind the edge of the window-like opening 14. The extensions 12 and 13 of the switching plunger 9 are held under prestress on the contact rocker 4. The end edge 11.1 of the outer fingers 11 forms a pivot bearing in its insert in the angle formed by the longitudinal beam of the contact rocker 4 and the wall 18 of the channel-shaped bend 17. As can be seen in particular from FIG. 4, a two-point support A-B for these outer fingers 11 is formed by the contact of the outer fingers 11 on the vertical wall 18 of the channel-shaped bend 17 and the apex of its extension 13 on the long sides of the side bends 6. The system D of the extension 12 of the middle finger 10 is located in the window-like opening 14 of the contact rocker 4, approximately on the center perpendicular C of the two-point support AB. This results in a solid three-point contact of the switching plunger 9 on the contact rocker 4, so that after each switching operation the switching plunger swings out 9 can always be automatically returned to the vertical starting position on the contact rocker 4.

Für die Lagerung der Zugfeder 5 an der Kontaktwippe 4 ist ein zwischen den Schaltstösseln 9 und parallel zu diesen liegender, gegen die Drucktaste 15 gerichteter Ansatz 8 vorgesehen, der bei der Bildung des einen fensterartigen Durchbruchs 14 aus der Kontaktwippe 4 ausgeschert ist.For the mounting of the tension spring 5 on the contact rocker 4, an approach 8 is provided between the switching plungers 9 and parallel to the latter, directed towards the pushbutton 15, which is swung out of the contact rocker 4 when a window-like opening 14 is formed.
