Abstract

A slide (2) in the housing (1) can move along a switching path (S) from a quiescent position into a switched position and back. The locking function is achieved by means of the interaction of a pin (6), supported on a moving bearing (8), with a guide curve (5, 13) which on the one hand has a locking step (b) and on the other hand, in the movement direction of the slide (2), has a linear extension (13) in which the pin (6) rests in the quiescent position of the slide (2). In order to simplify a space-saving design and functional movement it is provided that the bearing (8) can move parallel to the slide (2) between a first and a second position. It is further provided that, in the quiescent position of the slide (2), when the bearing (8) is located in the first position (Fig. 2a), the switching path (S) is shorter than the distance (A) of the pin (6) from the locking step (b) and is greater than said distance (A) when the bearing (8) is located in the second position (Fig. 2b). <IMAGE>

Description

Die vorliegende Erfindung bezieht sich auf einen Tastschalter gemäss dem Oberbegriff des Anspruchs 1.The present invention relates to a key switch according to the preamble of claim 1.

Ein derartiger Tastschalter ist aus der CH-PS 595 687 bekannt. Er hat den Vorteil, dass für die Tast- und Rastfunktion nicht je zwei verschiedene Schalter hergestellt und vom Verbraucher an Lager gehalten werden müssen. Der letztere kann die Tast­schalter bei ihrer Verwendung jeweils entsprechend der ge­wünschten Funktion einstellen. Bei diesem bekannten Tast­schalter ist neben der für die Rastfunktion vorgesehenen, nutförmigen Herzkurve eine lineare, nutförmige Kurve für die Tastfunktion vorgesehen. Je nach der gewünschten Funktionsart wird der Stift in die eine oder in die andere der beiden Kurven eingesetzt. Die Anordnung von zwei nutförmigen Kurven parallel nebeneinander ist raumbeanspruchend. Zudem ist bei Mikroschaltern der Stift schwer zugänglich und es ist nur bei sehr genauem Hinsehen erkennbar, ob er in der richtigen Kurve liegt.Such a key switch is known from CH-PS 595 687. It has the advantage that two different switches do not have to be made for the pushbutton and one for the latching function, and the consumer has to keep them in stock. The latter can set the pushbutton switches according to the desired function when they are used. In this known push button switch, in addition to the groove-shaped heart curve provided for the latching function, a linear groove-shaped curve is provided for the button function. Depending on the desired function, the pin is inserted in one or the other of the two curves. The arrangement of two groove-shaped curves parallel next to each other takes up a lot of space. In addition, the pin is difficult to access with microswitches and it is only possible to see if it is in the correct curve if you look very closely.

Die vorliegende Erfindung stellt sich die Aufgabe, einen Tastschalter der erwähnten Art derart zu verbessern, dass er unter Wahrung seines Vorteils raumsparender ausführbar ist und in der Ausführung als Mikroschalter die Umstellung in einfacher Weise erfolgen kann.The object of the present invention is to improve a pushbutton switch of the type mentioned in such a way that it can be carried out in a space-saving manner while maintaining its advantage, and the changeover can be carried out in a simple manner in the form of a microswitch.

Anhand der beiliegenden schematischen Zeichnung wird die Erfindung beispielsweise erläutert. Es zeigen:

  • Fig. 1 einen Längsschnitt durch einen Tastschalter,
  • Fig. 2 ein Detail aus Fig. 1 in Richtung des Pfeiles II ge­sehen, wobei Teile weggebrochen sind und
  • Fig. 3 eine Abwicklung der Herzkurve.
The invention is explained, for example, with the aid of the attached schematic drawing. Show it:
  • 1 shows a longitudinal section through a push button switch,
  • Fig. 2 seen a detail of Fig. 1 in the direction of arrow II, with parts broken away and
  • Fig. 3 is a development of the heart curve.

Der in der Zeichnung gezeigte Schalter weist im wesentlichen ein Gehäuse 1 auf, in dem axial verschiebbar ein Schieber 2 gelagert ist. Der Schieber 2 ist fest mit dem Druckhauben­träger 3 verbunden und befindet sich in seiner Ruhelage (in Fig. 1 mit ausgezogenen Strichen gezeigt), in der er durch eine nach oben wirkende Federkraft gehalten ist und gegen einen nicht sichtbaren Anschlag an der Gehäuseinnenseite anliegt. Mit dem Gehäuse 1 ist weiter ein Schaltelement 4 (strichpunktiert angedeutet), in dem die Schaltkontakte unter­gebracht sind. Wird der Schieber 2 durch einen Druck auf den Druckhaubenträger 3 um den Schaltweg S eingedrückt, betätigt er die im Schaltelement 4 untergebrachten Schaltkontakte. Auf der Schieberaussenseite befindet sich eine Kurve 5 in Form einer Nut, mit der ein Stift 6 im Eingriff ist. Der Stift 6 ist Teil eines Hebels 7, der mit seinem oberen hakenförmigen Ende in einem Lager 8 eingehakt und darin schwenkbar gelagert ist. Das als Lagerauge gestaltete Lager 8 wird von einer Blattfeder 9 gebildet, in die eine Schulter 10 eingeformt ist. Die Blattfeder 9 erzeugt eine auf den Hebel 7 wirkende Kraft, die den Stift 6 in Berührungskontakt mit dem Grund der Kurve 5 hält. Die Blattfeder 9 ist mit Reibschluss in einer Führungsnut 11 auf der Gehäuseinnenseite gehalten und zwischen der mit ausgezogenen Strichen gezeigten Stellung einerseits und der strichpunktiert gezeigten Stellung ander­ seits verschiebbar. Wird beispielsweise mittels eines Schrau­benziehers auf die Schulter 10 gedrückt, verschiebt sich die Blattfeder 9 aus der mit ausgezogenen Strichen gezeichneten Stellung nach oben in die strichpunktiert gezeichnete. Dabei schiebt sich das Lager 8 relativ zum Gehäuse 1 bzw. zum Schie­ber 2. Über dem Lager 8 weist die Blattfeder 9 eine Durch­brechung 14 auf, die dazu bestimmt ist, an einer an der Ge­häuseinnenseite angeordneten Rastnase 12 einzurasten, wenn die Blattfeder 9 die mit strichpunktierten Linien gezeich­nete Stellung einnimmt. Bei dieser Ausführungsform ist die Verrastung unlösbar, wodurch eine Rückstellung der Blattfeder 9 ausgeschlossen ist. Diese Rastverbindung kann indessen auch entfallen, wenn der Reibsitz der Blattfeder 9 in der Führungs­nut 11 hinreichend ist.The switch shown in the drawing essentially has a housing 1 in which a slide 2 is axially displaceably mounted. The slide 2 is firmly connected to the pressure hood support 3 and is in its rest position (shown in solid lines in FIG. 1), in which it is held by an upward spring force and rests against an invisible stop on the inside of the housing. With the housing 1 there is also a switching element 4 (indicated by dash-dotted lines) in which the switching contacts are accommodated. If the slide 2 is pressed in by a pressure on the pressure hood support 3 by the switching path S, it actuates the switching contacts accommodated in the switching element 4. On the outside of the slide there is a curve 5 in the form of a groove with which a pin 6 is engaged. The pin 6 is part of a lever 7 which is hooked with its upper hook-shaped end in a bearing 8 and is pivotally mounted therein. The bearing 8 designed as a bearing eye is formed by a leaf spring 9 into which a shoulder 10 is molded. The leaf spring 9 generates a force acting on the lever 7 which keeps the pin 6 in contact with the bottom of the curve 5. The leaf spring 9 is held with a friction fit in a guide groove 11 on the inside of the housing and between the position shown in solid lines on the one hand and the position shown in broken lines on the other movable on the side. If, for example, a shoulder 10 is pressed by means of a screwdriver, the leaf spring 9 moves upward from the position drawn with solid lines into the position shown in broken lines. The bearing 8 slides relative to the housing 1 or the slide 2. Above the bearing 8, the leaf spring 9 has an opening 14 which is intended to snap into a locking lug 12 arranged on the inside of the housing when the leaf spring 9 has the same dash-dotted lines assumed position. In this embodiment, the latching cannot be released, which means that the leaf spring 9 cannot be reset. This latching connection can, however, also be omitted if the friction fit of the leaf spring 9 in the guide groove 11 is sufficient.

Wie aus der Fig. 2 hervorgeht, schliesst unten an die herz­förmige Kurve 5 ein linearer Abschnitt 13 an, der so lang ist, dass in der Ruhelage des Schiebers 2 der Stift 6 immer in dieser Verlängerung liegt, gleichgültig, ob sich das Lager 8 in der unteren oder in der oberen Stellung befindet.As can be seen from FIG. 2, a linear section 13 adjoins the heart-shaped curve 5 at the bottom, which is so long that in the rest position of the slide 2 the pin 6 is always in this extension, regardless of whether the bearing 8 is in the lower or the upper position.

Die Tiefe der Kurve 5 (einschl. der Verlängerung 13) variiert und weist verschiedene Stufen auf, wie ihre Abwicklung in Fig. 3 veranschaulicht. Folgt man der Verlängerung 13 vom Punkt a nach oben und im Uhrzeigersinn um die herzförmige Kurve 5 wieder zurück nach unten, so steigt der Grund der Nut an, bis zu einer abfallenden Raststufe b. Von dort verläuft die Kurve 5 zu einer abfallenden Stufe c nach der sie wieder bis zu einer abfallenden Stufe d ansteigt. Danach steigt sie zu einer Stufe e, nach deren Überschreiten sie wieder gegen den Punkt a abfällt.The depth of the curve 5 (including the extension 13) varies and has different levels, as its development in Fig. 3 illustrates. If you follow the extension 13 from point a upwards and clockwise around the heart-shaped curve 5 back downwards, the bottom of the groove rises until a falling stop step b. From there, curve 5 runs to a descending step c, after which it rises again to a descending step d. Then it rises to a level e, after which it falls back to point a.

Befindet sich das Lager 8 in der in den Fig. 1 (mit ausge­zogenen Strichen) und Fig. 2A gezeigten Stellung, so ist der Schaltweg S des Schiebers 2 kleiner als der Abstand a des Stiftes 6 von der Raststufe b. Wird in dieser Lagerstellung der Schieber 2 um den Schaltweg S nach unten gedrückt, be­wegt sich der Stift 6 in der Kurve 5 lediglich bis zum Punkt f und kehrt nach der Freigabe des Schiebers 2 zum Punkt a zurück. Ein Einrasten des Schiebers 2 findet nicht statt. Wird das Lager 8 in die in Fig. 1 strichpunktierte Stellung verschoben (Fig. 2b), ist der Schaltweg S des Schiebers 2 grösser als der Abstand des Stiftes 6 von der Raststufe b. Nun folgt, wenn der Schieber 2 um den Schaltweg S nach unten gedrückt wird, der Stift 6 dem linken Ast der Kurve 5 und überschreitet die Raststufe b. Bei der Freigabe des Schiebers bewegt sich dieser nach oben und der Stift 6 folgt der Kurve 5 nach rechts unten und überschreitet die abfallende Stufe c. Nach dieser Stufe tritt der Schieber 2 mit dem Stift 6 in Formschluss und hindert diesen an der Rückkehr aus der Schaltlage in die Ruhelage. Der Schieber 2 ist eingerastet. Wird nun ein zweites Mal auf den Schieber 2 gedrückt und dieser anschliessend frei gegeben, folgt der Stift 6 der Kurve 5 weiter im Uhrzeigersinn und überschreitet nacheinander die abfallenden Stufen d und e bis er wieder den Ausgangs­punkt a in der Verlängerung 13 erreicht. Je nach dem ob das Lager 8 seine obere oder untere Stellung einnimmt, hat der Tastschalter somit eine Rast- oder Tastfunktion.If the bearing 8 is in the position shown in FIG. 1 (with solid lines) and FIG. 2A, the switching path S of the slide 2 is smaller than the distance a of the pin 6 from the detent step b. If in this storage position the slide 2 is pressed downwards by the switching path S, the pin 6 only moves in the curve 5 up to the point f and returns to the point a after the slide 2 is released. The slide 2 does not snap into place. If the bearing 8 is shifted to the dot-dash position in FIG. 1 (FIG. 2b), the switching path S of the slide 2 is greater than the distance of the pin 6 from the detent step b. Now, when the slide 2 is pressed down by the switching path S, the pin 6 follows the left branch of the curve 5 and exceeds the detent step b. When the slide is released, it moves upwards and the pin 6 follows the curve 5 to the bottom right and exceeds the descending step c. After this stage, the slide 2 engages with the pin 6 and prevents it from returning from the switching position to the rest position. The slide 2 is locked. If the slide 2 is now pressed a second time and this is then released, the pin 6 continues to follow the curve 5 clockwise and successively exceeds the descending steps d and e until it reaches the starting point a in the extension 13 again. Depending on whether the bearing 8 is in its upper or lower position, the key switch thus has a latching or key function.
