Abstract

1. An electric switch having a pivotable operating member (1) which acts on a contact rocker (2) by means of a sliding element (3) which is held in a receiver (5) of a switch lever (6) under the pressure of a spring (4), characterised in that the switch lever (6) has a lateral window (8) with the width of the spring (4) towards the receiver (5) ; and that, at the level of or below the window (8), there is provided a support (9) for a moulded body (10) formed on the sliding element (3).

Description

Die Erfindung bezieht sich auf einen elektrischen Schalter mit schwenkbarem Betätigungsglied, das auf eine Kontaktwippe mittels eines Gleitstückes einwirkt, das von einer Feder beaufschlagt in einer Aufnahme eines Schalthebels gehalten ist.The invention relates to an electrical switch with a pivotable actuator, which acts on a contact rocker by means of a slider, which is held by a spring in a receptacle of a switching lever.

Bei einem bekannten Schalter dieser Art nimmt das Gleitstück die Feder zu einer Montageeinheit auf und verrastet dann mit einem über die Feder hinausragenden Arm in einer hülsenförmigen Aufnahme (DE-C3-2 245 273).In a known switch of this type, the slider receives the spring into an assembly unit and then latches with an arm protruding beyond the spring in a sleeve-shaped receptacle (DE-C3-2 245 273).

Dieses Prinzip ist auch bei Hubkontakten für das Betätigungsglied der Gegenkontakte bekannt (US-A-2 871 322).This principle is also known in the case of stroke contacts for the actuating element of the mating contacts (US Pat. No. 2,871,322).

Bei einem anderen bekannten Schalter mit schwenkbarem Betätigungsglied bilden Feder und Gleitstück schon eine Konstruktionseinheit (DE-B-1 274 716). Diese erfordert für jede Schalterklasse eine Sonderfertigung.In another known switch with a pivotable actuator, the spring and slider already form a structural unit (DE-B-1 274 716). This requires special production for each switch class.

Mit solchen Konstruktionen vermeidet man das sonst übliche Fetten von Feder und Gleitstück, um dadurch diese während der Montage in der Aufnahme zu halten. Fett kann jedoch das Schaltverhalten des Schalters stören.With such constructions, the usual greasing of the spring and sliding piece is avoided in order to keep them in the receptacle during assembly. However, bold can interfere with the switching behavior of the switch.

Der andere Konstruktionsweg, die Feder auf einem am anderen Ende der Feder verrastbaren Träger aufzunehmen, dessen eine Stirnseite den Gleitkörper bildet, erfordert lange Träger bzw. Gleitstücke, die die Kalkulationen der Massenfertigung belasten.The other constructional way of receiving the spring on a support that can be locked at the other end of the spring, one end face of which forms the sliding body, requires long supports or sliding pieces that burden the calculations of mass production.

Der Erfindung liegt die Aufgabe zugrunde, einen Schalter zu entwickeln, der in seinem Kontaktbereich fettfrei sicher arbeitet, mit kurzen Gleitstücken auskommt und sich leicht montieren lässt.The invention has for its object to develop a switch that works safely in its contact area fat-free, manages with short sliders and is easy to assemble.

Die Lösung der geschilderten Aufgabe besteht darin, dass der Schalthebel ein seitliches Fenster mit der Breite der Feder zur Aufnahme hin aufwehst, die in Höhe oder unterhalb des Fensters ein Auflager für einen am Gleitstück ausgebildeten Formkörper aufweist.The solution to the described problem is that the shift lever has a side window with the width of the spring for receiving, which has a support for a molded body formed on the slider at height or below the window.

Bei einem solchen Schalter kann zunächst das Gleitstück durch das Fenster eingelegt werden und danach die Feder. Ein solcher Schalter kann den Schalthebel direkt am Betätigungsglied angeformt aufweisen oder beim üblichen Aufbau von Schaltern mit Grossflächenwippen kann die Wippe auf Zwischenglieder einwirken, die dann den Schalthebel betätigen.With such a switch, the slide can first be inserted through the window and then the spring. Such a switch can have the switching lever molded directly onto the actuating element or, in the usual construction of switches with large-area rockers, the rocker can act on intermediate elements which then actuate the switching lever.

Bei einem bekannten Schalter für geradlinige Hubbewegung wird die Feder in einem Schlitz angeordnet, der in seinem oberen Bereich einen Stift zur Verankerung der Feder aufnimmt oder eine Ausnehmung zum Einhängen der Feder aufweist. An ihrem unteren Ende wird sie in den Trägerfür Gegenkontakte eingehängt, der an der geschlitzten Aufnahme aufsteht (DE-C-960 746). Die Feder dient dabei als Befestigungsmittel zwischen Aufnahme und Träger der Gegenkontakte. Diese Bauweise erfordert ein zweimaliges Einhängen, was in maschineller Fertigung kaum und selbst wenn, dann nur unter grossem Aufwand möglich ist. Der erfindungsgemässe Schalter eignet sich dagegen für grosstechnische Fertigung und lässt sich andererseits auch leicht von Hand montieren.In a known switch for linear stroke movement, the spring is arranged in a slot which in its upper area receives a pin for anchoring the spring or has a recess for hanging the spring. At its lower end, it is hooked into the carrier for mating contacts, which stands up against the slotted receptacle (DE-C-960 746). The spring serves as a fastening means between the receptacle and carrier of the counter contacts. This construction method requires two hooks, which is hardly possible in machine production and even if it is only possible with great effort. In contrast, the switch according to the invention is suitable for large-scale production and, on the other hand, can also be easily assembled by hand.

Wenn das Fenster mit einer unteren Fensterbank höher als der obere Abschluss des Gleitkörpers ausgebildet ist, wird die Feder auch auf der Fensterseite zuverlässig gegen Herausfallen auch dann gesichert, wenn der obere Abschluss des Gleitkörpers nicht haubenartig in die Feder eingreift.If the window is designed with a lower window sill higher than the upper end of the sliding body, the spring on the window side is reliably secured against falling out even if the upper end of the sliding body does not engage the spring like a hood.

Der Schalter soll anhand eines in der Zeichnung grob schematisch wiedergegebenen Ausführungsbeispiels näher erläutert werden:

  • In Figur 1 ist das Prinzip eines Schalters mit schwenkbarem Betätigungsglied, teilweise im Schnitt dargestellt, veranschaulicht.
The switch is to be explained in more detail with reference to an exemplary embodiment shown roughly schematically in the drawing:
  • In Figure 1, the principle of a switch with a pivotable actuator, partially shown in section, is illustrated.

In Figur 2 ist ein Schalthebel mit erfindungsgemäss ausgebildeter Aufnahme im Längsschnitt dargestellt.FIG. 2 shows a shift lever with a receptacle designed according to the invention in a longitudinal section.

In Figur 3 ist ein Querschnitt, längs 111-111 nach Figur 2 genommen, dargestellt.FIG. 3 shows a cross section taken along 111-111 according to FIG. 2.

In Figur 4 ist die Ansicht des Schalthebels nach Figur 2 von der Fensterseite her gesehen wiedergegeben.FIG. 4 shows the view of the shift lever according to FIG. 2 seen from the window side.

In Figur 5 ist ein Gleitstück in der Ansicht nach Figur 4 dargestellt.In Figure 5, a slider is shown in the view of Figure 4.

Bei einem elektrischen Schalter mit schwenkbarem Betätigungsglied wirkt ein Betätigungsglied 1 auf eine Kontaktwippe 2 mittels eines Gleitstückes 3 ein, das von einer Feder 4 beaufschlagt ist. Gleitstück 3 und Feder 4 sind in einer Aufnahme 5 eines Schalthebels 6 angeordnet. Beim Verschwenken des Betätigungsgliedes 1 wird der Schalthebel 6 verschwenkt, so dass die Kontaktwippe 2 in den anderen Schaltzustand überführt wird. Elektrische Anschlüsse sind mit 7 bezeichnet.In the case of an electrical switch with a pivotable actuating element, an actuating element 1 acts on a contact rocker 2 by means of a sliding piece 3 which is acted upon by a spring 4. Slider 3 and spring 4 are arranged in a receptacle 5 of a shift lever 6. When pivoting the actuator 1, the switching lever 6 is pivoted so that the contact rocker 2 is transferred to the other switching state. Electrical connections are denoted by 7.

Die Aufnahme 5 des Schalthebels 6 weist ein aus Figur 2 ersichtliches Fenster 8 auf. Das Fenster hat die Breite der Feder 4, so dass diese durch das Fenster in die Aufnahme 5 eingelegt werden kann. In Fensterhöhe oder unterhalb des Fensters 8 befindet sich ein Auflager 9 für einen am Gleitstück 3 ausgebildeten Formkörper 10.The receptacle 5 of the shift lever 6 has a window 8 shown in FIG. 2. The window has the width of the spring 4 so that it can be inserted through the window into the receptacle 5. At window height or below window 8 there is a support 9 for a molded body 10 formed on slide 3.

Wenn das Fenster 8 mit seiner unteren Fensterbank 11 höher als der obere Abschluss 12 des Gleitkörpers 3 liegt, wird die Feder 4 sicher am Gleitkörper 3 gehalten. Statt dessen kann, wie im Ausführungsbeispiel, der obere Abschluss 12 des Gleitkörpers haubenförmig in die Feder 4 eingreifen.If the window 8 with its lower window sill 11 is higher than the upper end 12 of the sliding body 3, the spring 4 is held securely on the sliding body 3. Instead, as in the exemplary embodiment, the upper end 12 of the sliding body can engage in the hood 4 in the manner of a hood.

Die weiteren Figuren veranschaulichen Ausbildung und Aufbau von Gleitkörper 3 und Feder 4 im Schalthebel 6 noch deutlicher.The other figures illustrate the design and construction of sliding body 3 and spring 4 in the shift lever 6 even more clearly.
