Description

Die Erfindung bezieht sich auf einen elektrischen Installation - schalter 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.The invention relates to an 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 member and which is pivotally mounted on it from the pivot bearing at a symmetrical distance, approximately vertically projecting, self-resilient switching plunger can be switched over by a pushbutton which acts on the free ends of the switching plunger with a switching link and is under the action of a return force.

Bei der Ausbildung mehrpoliger Schalter ist es wichtig, daß ein synchron ablaufender Schaltvorgang der Umschaltkontakte gewährleistet werden kann. Bei bekannten Einrichtungen in der, eingangs beschriebenen Art, bei denen mehrere Kontaktwippen über an diesen angeordnete Schaltstößel durch eine gemeinsame Drucktaste betätigt werden, kann eine gemeinsame Umschaltung der Kontaktwippen nur durch eine äußerst genaue Parallelführung der Drucktaste erreicht werden (DE-OS 25 33 307). Aufgrund in der Fertigung auftretender Toleranzen ist jedoch eine zuverlässige synchrone Umschaltung solcher Kontaktsysteme nicht immer gewährleistet. Im übrigen ist auch die bekannte Einrichtung hinsichtlich der Anordnung von zwei doppelschenklig ausgeführten Schaltstößeln in Verbindung mit einem Gegenhebel an der Kontaktwippe äußerst aufwendig und kompliziert. iWhen forming multi-pole switches, it is important that a synchronous switching process of the changeover contacts can be guaranteed. In known devices of the type described at the outset, in which a plurality of contact rockers are actuated by a common push button via switching plungers arranged thereon, a common switching of the contact rockers can only be achieved by extremely precise parallel guidance of the push button (DE-OS 25 33 307) . However, due to tolerances occurring in production, reliable synchronous switching of such contact systems is not always guaranteed. In addition, the known device is extremely complex and complex with regard to the arrangement of two double-leg switching tappets in connection with a counter lever on the contact rocker. i

Aufgabe der Erfindung ist. es, einen Drucktastenschalter in der eingangs beschriebenen Art für die Anwendung von zwei oder mehreren Kontaktwippen, die durch eine gemeinsame Drucktastegeschaltet werden sollen, derart zu verbessern, daß mit wenigen Mitteln eine zuverlässige zwangsweise gemeinsame Umschaltung der Kontaktwippen gewährleistet werden kann. Dabei sollen die Kontaktwippen voneinander derart unabhängig sein, daß sie sich in der jeweiligen Kontaktgabe nicht gegenseitig stören.The object of the invention is. to improve a push button switch in the manner described at the outset for the use of two or more contact rockers which are to be switched by a common push button, that a reliable forcible common switching of the contact rockers can be guaranteed with few means. The contact rockers should be so independent of each other that they do not interfere with each other in the respective contact.

Erfindungsgemäß wird dies dadurch gelöst, daß zur Kupplung der Kontaktwippe mit mindestens einer weiteren Kontaktwippe je Kontaktwippe ein Mitnehmer aus Isolierstoff formschlüssig mit dieser verbunden vorgesehen ist, dem ein Kupplungsansatz angeformt ist zu einer zwangsweisen Mitnahme des benachbarten Mitnehmers.According to the invention, this is achieved in that for the coupling of the contact rocker with at least one further contact rocker per contact rocker, a driver made of insulating material is provided in a form-fitting manner, to which a coupling attachment is molded to forcefully take the neighboring driver.

Es ist hierdurch ermöglicht, daß bei einer Schaltbetätigung ein synchrones Umschalten der Kontakte gewährleistet ist, wobei in der jeweiligen Einschaltlage jedoch die Kontaktwippen jeweils voneinander unabhängig sind.This makes it possible to ensure synchronous switching of the contacts when the switch is actuated, but the contact rockers are each independent of one another in the respective switch-on position.

Nach weiterer Ausgestaltung ist der Mitnehmer mittels Rastansätzen an der Kontaktwippe befestigt.According to a further embodiment, the driver is attached to the contact rocker by means of latching projections.

Die Erfindung zeichnet sich weiter dadurch aus, daß die Kupplungsansätze der Mitnehmer klauenartig ineinandergreifen, derart, daß jeder Kupplungsansatz seitlich der durch das Schwenklager der Kontaktwippe gebildeten Symmetrieachse liegt, wobei ein Fortsatz des Kupplungsansatzes eine Stufe des Kupplungsansatzes des benachbarten Mitnehmers übergreift.The invention is further characterized in that the coupling approaches of the drivers engage in a claw-like manner, such that each coupling approach lies to the side of the axis of symmetry formed by the pivot bearing of the contact rocker, an extension of the coupling approach engaging over a step of the coupling approach of the adjacent driver.

Dabei weist der Übergriff von Fortsatz und Stufe einen Luftspalt auf.The overlap of the extension and step has an air gap.

Schließlich besteht die Erfindung noch darin, daß der Kupplungsansatz mit einer Aufnahme für die Halterung des selbstfedernden Schaltstößels versehen ist.Finally, the invention also consists in the coupling attachment being provided with a receptacle for holding the self-resilient switching plunger.

Der Installationsschalter nach der Erfindung ist in der Zeichnung an einem Ausführungsbeispiel dargestellt.The installation switch according to the invention is shown in the drawing using an exemplary embodiment.

In einem Schaltergehäuse 1 sind in der unteren Seitenwand ortsfeste Kontaktteile 2 und 3 befestigt. Der ortsfeste Kontaktteil 2 dient dabei als Schwenklager für eine an ihm mittels einer Feder 5 gehaltenen Kontaktwippe 4. Die Kontaktwippe 4 wird mittels einer Drucktaste 6, die in dem Gehäuse 1 längsverschieblich geführt ist, über Schaltstößel 16 in ihre bistabilen Lagen geschaltet. Dabei ist die Drucktaste 6 mittels im Gehäuse 1 gelagerter Rückführfedern 7 jeweils in ihre Ausgangslage rückführbar.Fixed contact parts 2 and 3 are fastened in a switch housing 1 in the lower side wall. The stationary contact part 2 serves as a pivot bearing for a contact rocker 4 held on it by means of a spring 5. The contact rocker 4 is switched by means of a pushbutton 6, which is guided in the housing 1 in a longitudinally displaceable manner, via switching plungers 16 into their bistable positions. The push button 6 can be returned to its starting position by means of return springs 7 mounted in the housing 1.

Für eine Kupplung mehrerer nebeneinander liegender Kontaktwippen 4, 4' ist an jeder dieser Kontaktwippen 4, 4' ein Mitnehmer 8, 8' befestigt. Wie aus Fig. 1 ersichtlich, wird dieser Mitnehmer 8 mittels Rastansätzen 9 innerhalb von Durchbrüchen 10 an den Kontaktwippen 4 formschlüssig gehalten.For coupling a plurality of contact rockers 4, 4 'lying next to one another, a driver 8, 8' is fastened to each of these contact rockers 4, 4 '. As can be seen from Fig. 1, this driver 8 is by means of locking lugs 9 within Openings 10 are held in a form-fitting manner on the contact rockers 4.

Wie insbesondere aus den Fig. 3 bis 5 ersichtlich, ist dem Mitnehmer 8, 8' ein in Richtung der benachbarten Kontaktwippe 4 bzw. 4' weisender Kupplungsansatz 11 bzw. 11' angeformt. Die Kupplungsansätze 11, 11' der benachbarten Mitnehmer 8, 8' greifen klauenartig ineinander. Dabei liegt jeder Kupplungsansatz 11, 11' seitlich der durch das Schwenklager der Kontaktwippe 4 bzw. 4' gebildeten Symmetrieachse 14. In dem dargestellten Beispiel besitzt jeder Kupplungsansatz 11 bzw. 11' einen Fortsatz 12 bzw. 12', der den gegenüberliegenden Kupplungsansatz 11 bzw. 11' jeweils an einer Stufe 13, 13' übergreift. Zum Ausgleich von Toleranzen zwischen den jeweiligen Kontaktbahnen weist der übergriff von Fortsatz 12 bzw. 12' und Stufe 13 bzw. 13' einen Luftspalt 17 auf.As can be seen in particular from FIGS. 3 to 5, the driver 8, 8 'is formed with a coupling projection 11 or 11' pointing in the direction of the adjacent contact rocker 4 or 4 '. The coupling lugs 11, 11 'of the adjacent drivers 8, 8' engage in a claw-like manner. Each coupling lug 11, 11 'is located laterally on the axis of symmetry 14 formed by the pivot bearing of the contact rocker 4 or 4'. In the example shown, each coupling lug 11 or 11 'has an extension 12 or 12' which the opposite coupling lug 11 or 11 'overlaps at a step 13, 13'. To compensate for tolerances between the respective contact tracks, the overlap of extension 12 or 12 'and step 13 or 13' has an air gap 17.

Jeder Kupplungsansatz 11, 11' ist noch mit einer Aufnahme 15 bzw. 15' für die Halterung je eines selbstfedernden Schaltstößels 16 versehen. Diese Aufnahme 15, 15' besteht aus einer zur Drucktaste 6 hin offenen Tasche, in die der Schaltstößel 16, der dreifingerig ausgeführt ist, mit seinen Fingern eingeführt wird. Der mittlere Finger des Schaltstößels ist an seinem freien Ende aus der Ebene des Schaltstößels 16 dachförmig ausgebogen und durchgreift einen Durchbruch der Tasche wobei er hinter einer Kante des Durchbruchs zur Anlage gelangt und die äußeren Finger gegen eine Seitenwand der Tasche drückt. Dabei liegen die vorderen Stirnkanten der äußeren Finger am Boden der Tasche auf und bilden hier ein Schwenklager bei Betätigung des Schaltstößels 16 durch die Drucktaste 6. Dadurch, daß die Schaltstößel 16 jeweils in den Kupplungsansätzen 11 bzw. 11' eingesetzt sind, wird für das Schaltsystem mit zwei Kontaktwippen 4, 4' nur ein paar Schaltstößel. 16 benötigt.Each coupling extension 11, 11 'is also provided with a receptacle 15 or 15' for holding a self-resilient shift plunger 16, respectively. This receptacle 15, 15 'consists of a pocket open towards the pushbutton 6, into which the switching plunger 16, which has three fingers, is inserted with its fingers. The middle finger of the switching plunger is bent out roof-shaped at its free end from the plane of the switching plunger 16 and passes through an opening in the pocket, coming to rest behind an edge of the opening and pressing the outer fingers against a side wall of the pocket. The front end edges of the outer fingers rest on the bottom of the pocket and here form a pivot bearing when the switching plunger 16 is actuated by the pushbutton 6. The fact that the switching plungers 16 are used in the coupling lugs 11 and 11 'is for the switching system with two contact rockers 4, 4 'only a few switching plungers. 16 needed.

Die Montage der Kontaktwippen 4, 4' mit den daran befestigten Mitnehmern 8, 8' mit Schaltstößel 16 in das Gehäuse 1 ist auch äußerst einfach. Dabei kann das Gehäuse 1 grundsätzlich eine unterschiedliche Ausgestaltung haben. Z.B. kann es topfförmig ausgeführt sein, wobei die ortsfesten Kontaktteile 2 und 3 und die Kontaktwippen 4 jeweils von oben in den Topf des Gehäuses 1 eingeführt werden können. Bei dem dargestellten Beispiel ist das Gehäuse 1 so ausgebildet, daß es seitlich offen ist und gewissermaßen einen Rahmen darstellt, in deren obere Wand in einen Durchbruch die Drucktaste 6 einsetzbar ist und in deren untere Wand von beiden Seiten die ortsfesten Kontaktteile 2 und 3 in Nischen eingelagert werden können. Ebenso werden die Kontaktwippen 4 bzw. 4' mit den daran befestigten Mitnehmern 8, 8' und den in diese eingesetzten Schaltstößel 16 von den offenen Seiten in das Gehäuse eingeführt. Dabei werden die Kupplungsansätze 11 bzw. 11' ineinandergreifend zusammengesteckt. Anschließend werden beide Seiten durch gleichförmige Isolierstoffplatten abgedeckt, die nach Befestigung an dem Gehäuse 1 die gesamte Schaltmechanik gegen äußere Einflüsse schützen und zuverlässig und fest lagern.The assembly of the contact rockers 4, 4 'with the attached carriers 8, 8' with switching plunger 16 in the housing 1 is also extremely simple. The housing 1 can basically have a different configuration. E.g. it can be pot-shaped, the stationary contact parts 2 and 3 and the contact rockers 4 can each be inserted from above into the pot of the housing 1. In the example shown, the housing 1 is designed such that it is open on the side and to a certain extent represents a frame, in the upper wall of which the push button 6 can be inserted into an opening and in the lower wall of the stationary contact parts 2 and 3 from both sides in niches can be stored. Likewise, the contact rockers 4 and 4 'with the carriers 8, 8' attached to them and the switching plungers 16 inserted into them are inserted into the housing from the open sides. The coupling lugs 11 and 11 'are pushed together. Subsequently, both sides are covered by uniform insulating material plates which, after being attached to the housing 1, protect the entire switching mechanism against external influences and store it reliably and firmly.

Für die Kupplung von mehr als zwei nebeneinander liegenden Kontaktwippen 4 können an den mittleren Kontaktwippen 4 Mitnehmer 8 vorgesehen werden mit zwei Kupplungsansätzen 11, die jedoch diagonal versetzt gegenüberliegend an dem Mitnehmer 8 angeformt sind, so daß diese wie in dem dargestellten Beispiel klauenartig ineinander greifen. iFor the coupling of more than two side-by-side contact rockers 4, drivers 8 can be provided on the middle contact rockers 4 with two coupling projections 11, which, however, are formed diagonally offset opposite one another on the driver 8, so that they engage in a claw-like manner in the example shown. i
