Es sei hervorgehoben, daß nur die zum Verständnis der Erfindung erforderlichen Konstruktionsteile dargestellt sind.It should be emphasized that only the structural parts required to understand the invention are shown.

Nach F i g. 1 a besteht die Einzeltaste aus dem Tastenschieber 1, der in einer nicht gezeigten Führung entgegen der Wirkung einer Feder 19 in Pfeilrichtung verschiebbar gelagert ist. Längs des Tastenschiebers ist eine Aussparung 10 von etwa rechteckigem Profil angeordnet, wodurch zwei in geringem Abstand zueinander liegende Vorsprünge 2 und 3 gebildet werden. Der dem Ende des Tastenschiebers benachbarte Vorsprung wirkt als Rastvorsnrung 3. Zwischen den Vorsprüngen ist ein längs des Tastenschiebers bewegbares Stellglied 4 gelagert, das den Rastvorsprung 3 etwas überragt. Dieses Stellglied ist mittels des Vorsprungs 2 in ein im wesentlichen hohle¹; und in Betätigungsrichtung sich verengendes Federelement 5 eindrückbar. In der gezeigten Stellung des Tastenschiebers liegt das Federende 6 an der Außenkante 7 des Rastvorsprunges 3 unter Spannung an. Es handelt sich hier um die Ausgangslage des Tasten-Schiebens, in der die Kontakte geöffnet bzw. bei Ruhekontakten geschlossen sind.According to FIG. 1 a, the single key consists of the key slide 1, which is mounted in a guide, not shown, against the action of a spring 19 so as to be displaceable in the direction of the arrow. A recess 10 with an approximately rectangular profile is arranged along the key slide, as a result of which two projections 2 and 3 located at a small distance from one another are formed. The projection adjacent to the end of the key slide acts as a latching projection 3. Between the projections, an actuator 4 which can be moved along the key slide and projects slightly beyond the latching projection 3 is mounted. This actuator is by means of the projection 2 in a substantially hollow ¹ ; and the spring element 5 narrowing in the actuating direction can be pressed in. In the position of the key slide shown, the spring end 6 rests on the outer edge 7 of the locking projection 3 under tension. This is the starting position of pushing a button, in which the contacts are open or closed in the case of normally closed contacts.

In F i g. 1 b befindet sich der Tastenschieber 1 in seiner Raststellung, in die er durch Betätigen des Knopfes in Pfeilrichtung gelangt. In dieser Stellung verrastet das Federende 6 selbsttätig an der Rastkante 8 des Rastvorsprunges 3. Durch die gleichzeitig hervorgerufene Verengung des Federelementes 5 wird das Stellglied 4 annähernd in seiner Ausgangslage (Fig. 1 a) festgehalten.In Fig. 1 b is the key slide 1 in its detent position, in which it can be reached by pressing the Button in the direction of the arrow. In this position, the spring end 6 locks automatically on the locking edge 8 of the locking projection 3. The narrowing of the spring element 5, which is caused at the same time the actuator 4 is held approximately in its starting position (Fig. 1 a).

Bei weiterem Drücken des Betätigungsknopfes in Pfeilrichtung gelangt der Tastenschieber 1 in die in F i g. 1 c dargestellte Auslösestellung. Bei diesem Vorgang wird das Stellglied 4 mittels des Vorsprunges 2 des Tastenschiebers in das verrastete Federende 6 eingedrückt und damit die Entriegelung des Tastenschiebers bewirkt. In der Auslösestellung des Tasienschiebers stützt sich das Federende 6 an der Außenfläche 9 des Stellgliedes 4 unter Spannung ab. Fig. 1 d zeigt einen gegenüber Fig. 1 c etwas späteren Zeitpunkt für die Auslösestellung des Tasten-Schiebers 1. Unter der Wirkung der Schraubenfeder 19, die in Fig. Ic stark verformt war, gelangt der Rastvorsprung 3 des Tastenschiebers entgegen der Betätigungsrichtung zunächst bis zum Anschlag an das Stellglied 4.If you continue to press the operating button in the direction of the arrow, the slide switch 1 moves into the position shown in F i g. 1 c shown release position. In this process, the actuator 4 by means of the projection 2 of the key slide pressed into the latched spring end 6 and thus the unlocking of the Key slide causes. In the release position of the pocket slide, the spring end 6 is supported on the Outer surface 9 of the actuator 4 from under tension. FIG. 1 d shows a somewhat later compared to FIG. 1 c Time for the release position of the key slide 1. Under the action of the coil spring 19, which was severely deformed in Fig. Ic, arrives Latching projection 3 of the key slide against the direction of actuation initially up to the stop the actuator 4.

ίο Schließlich zeigt die F i g. 1 e wieder die Ausgangslage des Tastenschiebers 1, die durch die weitere Entspannung der Schraubenfeder 19 erreicht wird. In dieser Stellung liegt das Federende 6 an der Außenkante 7 des Rastvorsprunges 3 unter Spannung an, während das Stellglied 4 innerhalb des Federelementes 5 angeordnet ist.ίο Finally, the F i g. 1 e again the starting position of the key slide 1, which is achieved by the further relaxation of the helical spring 19. In In this position, the spring end 6 rests on the outer edge 7 of the locking projection 3 under tension, while the actuator 4 is arranged within the spring element 5.

Die in den F i g. 2 a bis 2 c dargestellte Einzeltaste ist in Flachbauweise ausgei^art. Zu diesem Zweck ist der Tastenschieber 1 durch Ausstanzen aus BlechThe in the F i g. 2 a to 2 c shown single button is designed in flat design. To that end is the key slide 1 by punching out of sheet metal

so oder bandförmigem Flachmaterial hergestellt. Er ist wiederum mit einer Aussparung 10 xlti etwa rechteckigem Profil versehen. Das Federelement besteht vorzugsweise aus zwei einseitig abgewinkelten länglichen Blattfedern 11 und 12, die sich in spiegelbildlieher Anordnung gegenüberliegen. Als Stellglied wird eine die Aussparung 10 lose umklammernde Krampe 13 verwendet, die zweckmäßig durch Ausstanzen aus Blech und Umbiegen der Enden hergestellt ist.so or band-shaped flat material produced. It is in turn provided with a recess 10 xlti approximately rectangular profile. The spring element preferably consists of two elongated leaf springs 11 and 12 which are angled on one side and which lie opposite one another in a mirror-image arrangement. A staple 13 loosely clasping the recess 10 is used as the actuator, which is expediently produced by punching out of sheet metal and bending the ends.

Besondere Vorteile ergeben sich bei einer Ausführungsform der Einzeltaste, bei der das Federelement 5, der Tastenschieber 1 mit seiner Aussparung 10 und das Stellglied 4 in bezug auf die Schaltachse rotationssymmetrisch ausgebildet sind. Zu diesem Zweck können der Tastenschieber 1, das Federelement 5 und das Stellglied 4 als Metallurehteile ausgeführt sein. Zum Beispiel kann das Federelement 5 aus einem geschlitzten, einseitig gebördelten Rohr bestehen. Entsprechend wird das Stellglied 4 aus einem Ring mit einer auf die Aussparung 10 lose passenden Bohrung hergestellt.Particular advantages result from an embodiment of the single key in which the spring element 5, the key slide 1 with its recess 10 and the actuator 4 with respect to the switching axis are designed to be rotationally symmetrical. For this purpose, the key slide 1, the spring element 5 and the actuator 4 be designed as Metallurehteile. For example, the spring element 5 consist of a slotted tube flanged on one side. The actuator 4 is correspondingly off a ring with a hole that fits loosely on the recess 10.

In F i g. 3 ist dargestellt, wie der Tastenschieber 1, das Stellglied 4 und das Federelement 5 aus einem einzigen Kunststoffteil bestehen, das durch Spritzgießen hergestellt ist. Es ist dabei das Federelement 5 zugleich mit einem Fortsatz 14 zur Führung des Tastenschiebers 1 versehen. Das Federelement S wird also zusammen mit dem Fortsatz 14 und der Abdeckplatte 15 des Drucktastenschalters einstückig hergestellt. Es ist zweckmäßig, in diesem Falle dasIn Fig. 3 shows how the key slide 1, the actuator 4 and the spring element 5 consist of a single plastic part, which is injection molded is made. It is the spring element 5 at the same time with an extension 14 for guiding the key slide 1 provided. The spring element S is thus together with the extension 14 and the cover plate 15 of the push button switch made in one piece. It is useful in this case that
