Derartige Betätiger werden zur Befehlseingabe an so genannten Maschinen/Mensch-Schnittstellen regelmäßig verwendet. Dabei ist nicht nur eine Verwendung zur Schaltung von Steuerströmen, sondern auch für Leistungsschaltungen denkbar, indem der Betätiger als Auslöser für Leistungsschalter eingesetzt wird. An diese Betätiger werden hohe Anforderungen bezüglich Lebensdauer, Robustheit sowie Abdichtung des elektrischen Teils gegen Wasser und Schmutz gestellt. Außerdem soll die Herstellbarkeit möglichst kostengünstig und prozesssicher sein.

Das bedeutet, sie beste¬ hen aus einem Druckknauf, einem Befestigungsteil, wie zum Beispiel einer Ringmutter oder einem Montagehalter und einem oder mehreren Schaltelementen, die als Öffner- oder Schließerschaltglieder ausgeführt sind. Zur Montage wird der Betä¬ tiger in der Regel von vorn durch ein Loch in der Schalttafel geführt und von hinten mittels eines Befestigungsteils mon¬ tiert. Die Schaltelemente werden mit Schrauben, Schnapphaken oder Riegeln mechanisch am Betätiger oder am Befestigungsteil befestigt. Die elektrische Verbindung der Schaltelemente mit der Steuerung erfolgt über Anschlussklemmen. Cabinet doors or housing cover mounted. Command devices are generally modular.

Bei Sicherheitsanwendungen, wie zum Beispiel Not-Aus-Befehls- geräten ist es Vorschrift, dass das Signal durch das Öffnen von zwangsöffnenden Kontakten erzeugt wird. Das heißt, dass bei einem unbetätigten Not-Aus-Befehlsgerät die Kontakte und damit der zugehörige Stromkreis geschlossen sind. Im Stö- rungs- oder Notfall wird durch Schlagen auf den Not-Aus- Betätiger, der sich vor der Schalttafel befindet, der Öffnerkontakt unterbrochen und die Anlage oder Maschine in einen sicheren Zustand versetzt. Dies funktioniert jedoch nur, wenn die räumliche Zuordnung zwischen Betätiger und Schaltelement sichergestellt ist. Durch mangelhafte Montage oder durch Ge¬ walteinwirkung kann es vorkommen, dass die Schaltelemente mechanisch vom Betätiger getrennt werden. In diesem Fall ist das Not-Aus-Befehlsgerät nicht mehr funktionsfähig. Das heißt, bei einer Betätigung im Notfall werden die Kontakte nicht geöffnet und damit erfolgt auch keine Beseitigung des Gefahrenzustands. Dies kann zu fatalen Schäden für Mensch und Maschine führen. Daher kommt der sicheren Verbindung zwischen Betätiger und Schaltelement eine wesentliche Bedeutung zu. For safety applications, such as emergency stop devices, it is mandatory that the signal is generated by opening positive-opening contacts. This means that with an unconfirmed emergency stop command device, the contacts and thus the associated circuit are closed. In the disturbance In the event of an emergency or emergency, the NC contact is interrupted by striking the emergency stop actuator located in front of the control panel and the system or machine is placed in a safe condition. However, this only works if the spatial assignment between the actuator and the switching element is ensured. Due to poor assembly or by Ge ¬ walteinwirkung it may happen that the switching elements are mechanically separated from the actuator. In this case, the emergency stop command device is no longer functional. That is, in an emergency operation, the contacts are not opened and thus there is no elimination of the dangerous condition. This can lead to fatal damage to man and machine. Therefore, the secure connection between actuator and switching element is essential.
Die Forderung nach einer integrierten optischen Anzeige, bei der es sich sowohl um eine mechanische und/oder elektrische Schaltanzeige handelt, führt zu der Problematik der Unter¬ bringung der erforderlichen Bauteile, da das Gesamtvolumen des Gerätes, insbesondere durch einen genormten Einbaudurchmesser (zum Beispiel 22,5 mm) nur in engen Grenzen variiert werden kann. Bisher wurde, wenn eine Integration der Anzeige in das Befehlsgerät nicht möglich war, meist eine zusätzliche Befehlsstelle, beispielsweise mit einem Leuchtmelder, ange- bracht. Auf Grund des zusätzlichen Platzbedarfs, zum Beispiel auf einer Schalttafel der Installationseinheit und der zwin¬ genden Verwendung einer separaten Anzeige, ist diese Lösung unvorteilhaft . Aus der DE 100 11 624 Cl geht eine Not-Aus-Taste hervor mit einem pilzförmigen Betätigungskopf und einem aus verschiede¬ nen Teilen zusammengesetzten Grundkörper mit einer fest angeordneten Tastenführung mit mindestens einem beweglichen Teil und mit einer Verriegelungsanordnung, die bei gedrückter Not- Aus-Taste diese in der "Gedrückt "-Stellung hält, wobei dieThe requirement for an integrated optical display in which there is both a mechanical and / or electrical switching display, leading to the problem of sub ¬ brin supply of components required, since the total volume of the device, in particular (by a standardized fitting diameter, for example 22 , 5 mm) can only be varied within narrow limits. Previously, when an integration of the display in the command device was not possible, usually an additional command point, for example with a light-emitting, attached. Due to the additional space requirement, for example on a control panel of the installation unit and the zwin ¬ ing use of a separate display, this solution is unfavorable. From DE 100 11 624 Cl a emergency stop button shows a mushroom-shaped actuating head and a composite of Various ¬ NEN parts base body with a fixedly arranged button guide with at least one movable part and with a locking arrangement which while holding down the emergency switch Button holds it in the "pressed" position, with the
Not-Aus-Taste durch Zug und/oder Drehung des Betätigungskop¬ fes entriegelbar ist. Der Betätigungskopf weist eine Öffnung auf, in der eine die Öffnung verschließende Linse einsetzbar ist, die von einem am gegenüber liegenden Ende des Betätigungskopfs angeordneten Leuchtelement beleuchtbar ist, wobei die Verriegelungsanordnung zwischen dem Leuchtelement und dem Betätigungskopf angeordnet ist, und wobei die Verriegelungs- anordnung in lichtdurchlässiger Weise ausgebildet oder angeordnet ist, und wobei die festen und beweglichen Teile axiale Lichtdurchtrittsöffnungen aufweisen . Emergency stop button by train and / or rotation of Betätigungskop ¬ fes is unlocked. The actuating head has an opening in which a lens closing the opening can be used is illuminated by a arranged at the opposite end of the actuating head luminous element, wherein the locking arrangement between the luminous element and the actuating head is arranged, and wherein the locking arrangement is formed or arranged in a translucent manner, and wherein the fixed and movable parts axial Have light openings.
Nachteilig an diesem Stand der Technik ist, dass die Verrie- gelungsanordnung zwischen Leuchtelement und Betätigungskopf angeordnet ist, so dass das Licht nicht ohne Hindernis zum Betätigungskopf geführt werden kann. A disadvantage of this prior art is that the locking arrangement between the luminous element and the actuating head is arranged, so that the light can not be passed without hindrance to the operating head.
Demgemäß besteht die Aufgabe der vorliegenden Erfindung dar- in, einen Betätiger mit einer beleuchteten Signalanzeige zu schaffen, bei welchem das Licht ungehindert zum Betätigungs¬ kopf geführt werden kann. Accordingly, the object of the present invention is to provide an actuator with an illuminated signal display, in which the light can be passed unhindered to the actuation ¬ head.

This object is achieved by an actuator having the features of patent claim 1. Advantageous education and further ¬ education, which can be used individually or in combination with each other, are the subject of the dependent claims. According to the invention this object is achieved by an actuator ge ¬ trig , which is provided for switching a switching unit and having a display having a window and a lighting ¬ tion element. The invention is characterized in that the lighting element is designed as an LED, wherein the light of the LED is guided via a directly in the actuated state, ie directly or without obstruction, arranged above the LED light guide.
