Description

Die Neuerung bezieht sich auf einen Befehlsschalter mit einer Schlüsselrosette und einem ersten Schalteinsatz, wobei der Schlüssel zur Betätigung des ersten Schalteinsatzes von einer Aus- in eine Ein-Stellung verdrehbar und in der Aus-Stellung abziehbar ist sowie einem zweiten Schalteinsatz, der schlüsseleinschubabhängig betätigbar ist.The innovation relates to a command switch with a key escutcheon and a first switch insert, the key for actuating the first switch insert being rotatable from an off to an on position and being removable in the off position, and a second switch insert which can be actuated depending on the key insert .

Bei einem bekannten Befehlsschalter mit einer Schlüsselrosette ist neben einem Schalteinsatz, der zur Betätigung von einer Ausin eine Ein-Stellung verdrehbar und in der Aus-Stellung abziehbar ist, ein weiterer Schalteinsatz vorgesehen, der beim Einstecken eines Schlüssels geschlossen oder geöffnet wird, womit die eingesteckte Lage des Schlüssels angezeigt werden kann. Der Schlüssel muß hier bewußt herausgezogen werden, wodurch die Schalthandlung des Schalteinsatzes und damit die Anzeige eingeleitet wird. Die Betätigung des weiteren Schalteinsatzes erfolgt bei dieser Ausführungsform über einen am Boden des Zylinders in der Schlüsselrosette befindlichen Verlängerungsstößel, d.h. der Schalteinsatz wird nur bei voll eingesteckter Position betätigt.In a known command switch with a key escutcheon, in addition to a switch insert which can be rotated to an on position from an off position and which can be removed in the off position, a further switch insert is provided which is closed or opened when a key is inserted, thereby inserting the key Location of the key can be displayed. The key must be deliberately removed here, which initiates the switching operation of the switch insert and thus the display. In this embodiment, the further switching insert is actuated via an extension plunger located in the base of the cylinder in the key rosette, i.e. the switch insert is only activated when the position is fully inserted.

Der Neuerung liegt daher die Aufgabe zugrunde, den bekannten Befehlsschalter dahingehend zu verbessern, daß mit in beliebiger Position steckendem, d.h. selbstgehaltenem Schlüssel, eine Betätigung des nach obiger Darstellung zusätzlichen Schalteinsatzes verbunden ist.The innovation is therefore based on the object of improving the known command switch in such a way that with the self-held key, an actuation of the additional switching insert as shown above is connected.

Diese Aufgabe wird dadurch gelöst, daß die Schlüsselrosette im Bereich der Einführöffnung für den Schlüssel ein Betätigungselement für den zweiten Schalteinsatz aufweist und die Einführöffnung derart ausgebildet ist, daß der Schlüssel erst in einer Position mit einer Mindesteinstecktiefe, in der eine Betätigung des zweiten Schalteinsatzes sichergestellt ist, in der Schlüsselrosette ohne äußere Unterstützung gehalten wird.This object is achieved in that the key rosette has an actuating element for the second switching insert in the area of the insertion opening for the key and the insertion opening is designed such that the key only in one Position with a minimum insertion depth, in which an actuation of the second switching insert is ensured, in which the escutcheon is held without external support.

Anhand der Zeichnung wird ein Ausführungsbeispiel gemäß der Neuerung beschrieben. Der in der Zeichnung dargestellte Befehlsschalter besteht aus einer Schlüsselrosette 1 und Schalteinsätzen, 2,3 von denen der zweite als Mikroschalter 2 mit einem halbkugelförmig vorstehenden Betätigungsteil ausgeführt ist. An dieses schließt sich als eigentliches Betätigungselement eine Kugel 5 an, die in die Zylinderöffnung für den Schlüssel 6 in der Schlüsselrosette 1 hineinragt. Das Betätigungselement 5 befindet sich im Bereich der zur Frontseite hin aufgeweiteten Einführöffnung 4 für den Schlüssel 6 in der Schlüsselrosette 1. Diese Ausführung hat zur Folge, daß der Schlüssel 6 in dem Zylinder solange nicht selbsthaltend stecken bleibt, wie er noch keine Umschaltung des Mikroschalters 2 über das Betätigungselement 5 bewirkt hat.An exemplary embodiment according to the innovation is described with the aid of the drawing. The command switch shown in the drawing consists of a key rosette 1 and switch inserts, 2, 3 of which the second is designed as a microswitch 2 with a hemispherical actuating part. This is followed by a ball 5 as the actual actuating element, which projects into the cylinder opening for the key 6 in the key rosette 1. The actuating element 5 is located in the area of the insertion opening 4 for the key 6 in the key rosette 1, which is widened towards the front. This embodiment has the consequence that the key 6 does not remain stuck in the cylinder as long as it has not yet switched over the microswitch 2 caused by the actuator 5.

Claims (1)

  1. Control switch having a key collar (1) and a first switch module (3), in which case the key (6) can be twisted for the actuation of the first switch module (3) from an off-position into an on-position and can be withdrawn in the off-position, and also having a second switch module (2) which can be actuated in a manner dependent upon the key insertion, characterised in that the key collar (1) has, in the region of its entrance opening (4) for the key (6), an actuating element (5) for the second switch module (2) and the entrance opening (4) is formed in such a way that the key (6) is first held in the key collar (1) without external support in a position with a minimum plug-in depth in which actuation of the second switch module (2) is guaranteed.
