The holder 17 itself can also be positioned in the hollow rod 5 and be fixed in position by means of the conductor parts 4.

Um beim Hineindrücken des Druckstücks 10 den Schalter 20 betätigen zu können, ist innerhalb des Hohlstabs 5 zwischen dem Druckstück 10 und dem Schalter 20 ein Schaltstück 22 vorgesehen, das in Längsrichtung des Hohlstabs 5 gegen einen Stößel 23 des Schalters 20 verlagerbar ist. Das Schaltstück 22 kann an Führungsschienen 42 gelagert sein und einen Schaltbolzen 24 besitzen, der mit dem Stößel 23 korrespondiert. Dem Schaltstück 22 ist zweckmäßig eine Druckfeder 25 zugeordnet, die innerhalb des Hohlstabs 5 auf der Halterung 17 abgestützt ist und bewirkt, dass das Schaltstück 22 und das darüber befindliche Druckstück 10 nach oben, also von dem Stößel 23 weg, gedrückt werden. Außerdem ist in dem Hohlstab 5 eine Überhubfeder 26 vorgesehen, die zwischen dem Druckstück 10 und dem Schaltstück 22 angeordnet ist. Somit sind alle elektrotechnisch relevanten Leucht- und Schaltteile, wie Leuchtdiode 18, Leiterplatte 15, Bauteile 19, Schaltstück 22, Druckfeder 25, Überhubfeder 26 und Schalter 20, platzsparend hintereinander und zum Teil auch nebeneinander ausschließlich innerhalb des druckfest gekapselten Raums des rohrförmigen Hohlstabs 5 gelagert.To actuate the switch 20 when pushing in the pressure piece 10 can, is within the hollow rod 5 between the pressure piece 10 and the Switch 20 a contact piece 22 is provided, which is in the longitudinal direction of the hollow rod 5 is displaceable against a plunger 23 of the switch 20. The Switch 22 can be mounted on guide rails 42 and one Have switching pin 24, which corresponds to the plunger 23. the Contact piece 22 is suitably assigned a compression spring 25, which is within of the hollow rod 5 is supported on the holder 17 and causes that Switch piece 22 and the pressure piece 10 above it, that is be pushed away from the plunger 23. In addition, in the hollow rod 5th an overtravel spring 26 is provided between the pressure piece 10 and the Switch piece 22 is arranged. Thus, all are relevant to electrical engineering Luminous and switching parts, such as light-emitting diode 18, printed circuit board 15, components 19, Switch piece 22, compression spring 25, overstroke spring 26 and switch 20, space-saving one after the other and sometimes also side by side exclusively within of the flameproof encapsulated space of the tubular hollow rod 5.

Wie der Zeichnung weiterhin zu entnehmen ist, kann die Meldeleuchte einen Betätigungsvorsatz 27 aufweisen, der den aus dem Deckel 2 herausragenden Teil des Hohlstabs 5 und das Druckstück 10 übergreift. Der Betätigungsvorsatz 27 weist ein den Hohlstab 5 rohrförmig umschließendes Einsatzgehäuse 28 mit einer Gewindemutter 29 auf und kann an einer Montagewand 30 befestigt sein, die zwischen der Gewindemutter 29 und einem Frontring 31 gelagert ist, wobei zwischen dem Lochrand der Montagewand 30 und dem Einsatzgehäuse 28 sowie dem Frontring 31 ein Dichtungsring 32 vorgesehen sein kann. Die an dem Einsatzgehäuse 28 drehbar gelagerte Gewindemutter 29 wird dabei fest gegen die Innenseite der Montagewand 30 geschraubt, so dass der Betätigungsvorsatz 27 lagesicher montiert ist.As can be seen from the drawing, the indicator light can be switched on Have actuating attachment 27, which protrudes from the cover 2 Part of the hollow rod 5 and the pressure piece 10 engages. The actuator 27 has an insert housing tubularly enclosing the hollow rod 5 28 with a threaded nut 29 and can on a mounting wall 30 be attached between the threaded nut 29 and a front ring 31st is mounted, the mounting wall 30 and the Insert housing 28 and the front ring 31, a sealing ring 32 is provided can be. The threaded nut rotatably mounted on the insert housing 28 29 is screwed firmly against the inside of the mounting wall 30, so that the actuator 27 is mounted securely.

Darüber hinaus weist der Betätigungsvorsatz 27 eine lichtdurchlässige Leuchtkappe 33 auf, die die Leuchtkuppe 14 des Druckstücks 10 übergreift. Die Leuchtkappe 33 ist einer Adapterhülse 34 zugehörig, die wiederum dem Druckstück 10 zugehörig ist, so dass bei einer Schaltbetätigung sowohl das Druckstück 10 als auch die Leuchtkappe 33 mit der Adapterhülse 34 axial verlagert werden. Die Adapterhülse 34 ist von einer als Druckfeder ausgebildeten Stützfeder 35 unterstützt, die an einer Hülse 36 abgestützt ist. Um am Betätigungsvorsatz 27 nach oben hin einen dichten Abschluss zu erzielen, kann eine Formdichtung 37 vorgesehen sein, die mit einem Bund 38 in einer Nut des Einsatzgehäuses 28 gelagert und mittels des Frontrings 31 gehalten ist. Wie der Zeichnung zu entnehmen ist, werden die Randbereiche der Leuchtkappe 33 und der Adapterhülse 34 von einem Kragen 39 der Formdichtung 37 übergriffen und abgedichtet, wobei die dichte Anlage an dem Kragen 39 nach dem Verbinden des Nut/Feder-Segmentes 43 entsteht. Diese Verbindung kann zweckmäßig durch Kleben oder durch Ultraschallschweißung hergestellt sein.In addition, the actuator 27 has a translucent Light cap 33, which engages over the light cap 14 of the pressure piece 10. The light cap 33 is associated with an adapter sleeve 34, which in turn the Pressure piece 10 is associated, so that both when switching Thrust piece 10 and the light cap 33 with the adapter sleeve 34 axially be relocated. The adapter sleeve 34 is designed as a compression spring Support spring 35 supported, which is supported on a sleeve 36. To on Actuator 27 to achieve a tight seal upwards A molded seal 37 can be provided, which with a collar 38 in a Groove of the insert housing 28 mounted and held by means of the front ring 31 is. As can be seen in the drawing, the edge areas of the Light cap 33 and the adapter sleeve 34 from a collar 39 of the Form seal 37 overlapped and sealed, the tight system on the Collar 39 is formed after connecting the tongue and groove segment 43. This Connection can be conveniently by gluing or by ultrasonic welding be made.

In der gedrückten Schaltstellung (FIG. 3) ist das Druckstück 10 mit der Leuchtkappe 33 und der Adapterhülse 34 gegen die Kraft der Stützfeder 35 axial nach unten gedrückt worden, und zwar so weit, dass eine Anschlagfläche 44 der Adapterhülse 34 an der Stirnfläche 45 des Endbereichs 9 des Hohlstabs 5 anliegt, so dass eine sichere Abstützung gegeben ist. Darüber hinaus sind weitere Sicherheitsanschläge gegeben, indem eine nach unten weisende Randfläche 46 der Adapterhülse 34 auf einer nach oben weisenden Ringfläche 47 der Hülse 36 aufliegt, eine nach unten weisende Endfläche 48 der Adapterhülse 34 auf einer Bundfläche 49 der Hülse 36 aufliegt und ein Vorsprung 50 der Adapterhülse 34 an einer nach oben gerichteten Stegfläche 51 des Einsatzgehäuses 28 anschlägt. Dadurch ist eine Vierfachabstützung bei der Druckbetätigung gegeben, so dass auch große Schlagkräfte sicher aufgefangen werden und keine mechanischen Beschädigungen auftreten können.In the pressed switch position (FIG. 3), the pressure piece 10 with the Light cap 33 and the adapter sleeve 34 against the force of the support spring 35 have been pushed axially downwards, so far that a stop surface 44 of the adapter sleeve 34 on the end face 45 of the end region 9 of the Hollow rod 5 abuts so that there is secure support. About that In addition, further security attacks are given by one down facing edge surface 46 of the adapter sleeve 34 on an upward facing Ring surface 47 of the sleeve 36 rests, an end surface 48 pointing downward the adapter sleeve 34 rests on a collar surface 49 of the sleeve 36 and a Projection 50 of the adapter sleeve 34 on an upward web surface 51 of the insert housing 28 strikes. This is a quadruple support given the pressure actuation, so that even large impact forces safely are caught and no mechanical damage occurs can.

In der gedrückten Schaltstellung ist das Schaltstück 22 gegen die Kraft der Druckfeder 25 so weit nach unten verlagert worden, dass der Stößel 23 von dem Schaltbolzen 24 zur Betätigung des Schalters 20 ganz hineingedrückt ist. Weiterhin ist in der FIG. 3 zu erkennen, dass auch die Überhubfeder 26 gegenüber der Darstellung in FIG. 2 etwas zusammengedrückt worden ist, so dass keine starren Kräfte auf den Schalter 20 einwirken und diesen somit auch nicht schädigen können.In the depressed switching position, the contact piece 22 is against the force of the Compression spring 25 has been moved so far down that the plunger 23 from the switching pin 24 is pressed all the way to actuate the switch 20. Furthermore, in FIG. 3 to recognize that the overtravel spring 26 compared to the representation in FIG. 2 something has been compressed, so that no rigid forces act on the switch 20 and thus this can't harm either.

Zur Erzielung einer gleichmäßigen und hellen Ausleuchtung kann es günstig sein, mindestens die der Leuchtdiode 18 zugewandte halbkugelförmige Innenfläche 40 der Leuchtkuppe 14 des Druckstücks 10 so auszubilden, dass sie eine feinperlige Struktur aufweist. Die Innenfläche 40 kann somit eine Vielzahl kleiner kugelförmiger bzw. perlförmiger Erhebungen und eine Vielzahl kleiner Mulden haben, die abwechselnd unmittelbar nebeneinander liegen, so dass die Innenfläche 40 nicht glatt, sondern fein aufgeraut ist. Eine derart feingeraute Innenflächenstruktur kann vorzugsweise durch Erodieren, Ätzen, Kornstrahlen oder durch eine entsprechende Gestaltung der Formoberfläche erzielt werden. Die feingeraute Innflächenstruktur bewirkt, dass das von der Leuchtdiode 18 ausgesandte Licht sich an der gesamten Innenfläche 40 der Leuchtkuppe 14 so bricht und verfängt, dass die Leuchtkuppe 14 insgesamt als ein einheitlich großer Leuchtkörper leuchtet. Darüber hinaus kann es günstig sein, das Druckstück 10 insgesamt, mindestens aber die Leuchtkuppe 14 diffus milchig oder milchig/farbig fluoreszierend einzufärben. Durch eine solche Einfärbung wird die Lichtdurchlässigkeit derart reduziert, dass bei eingeschalteter Leuchtdiode 18 ein gewisses Eigenleuchten des Druckstücks 10 bzw. der Leuchtkuppe 14 auftritt, wodurch die Ausleuchtung noch gleichmäßiger und intensiver ist.It can be cheap to achieve a uniform and bright illumination be at least the hemispherical one facing the light-emitting diode 18 Form the inner surface 40 of the light cap 14 of the pressure piece 10 in such a way that it has a fine pearly structure. The inner surface 40 can thus be a Large number of small spherical or pearl-shaped elevations and a large number have small troughs that are alternately directly next to each other, so that the inner surface 40 is not smooth, but finely roughened. Such a finely roughened inner surface structure can preferably be produced by eroding, etching, Grain blasting or by an appropriate design of the mold surface be achieved. The fine-roughened inner surface structure means that the Light emitting diode 18 emitted light on the entire inner surface 40 of the Light cap 14 breaks and catches so that the light cap 14 as a whole shines as a uniformly large illuminant. Furthermore, it can be cheap, the pressure piece 10 overall, but at least the light cap 14 colored diffuse milky or milky / colored fluorescent. By a such coloring, the light transmittance is reduced so that at switched on light-emitting diode 18 a certain self-illumination of the pressure piece 10 or the light cap 14 occurs, which makes the illumination even more uniform and is more intense.

Wie die Leuchtkuppe 14, so besteht auch die Leuchtkappe 33 aus einem lichtdurchlässigen Material und überdeckt die Leuchtkuppe 14 in einem geringen Abstand. Die der Leuchtkuppe 14 zugewandte Innenseite 41 der Leuchtkappe 33 kann ebenfalls eine feinperlige Struktur haben. Diese Struktur kann so ausgeführt sein, dass eine Vielzahl kleiner perlförmiger Erhebungen und eine Vielzahl kleiner Mulden abwechselnd unmittelbar nebeneinander liegen, so dass die Innenseite 41 fein aufgeraut ist. Diese feingeraute Innenseitenstruktur kann im wesentlichen gleich der feingerauten Innenflächenstruktur der Leuchtkuppe 14 ausgeführt und nach dem gleichen Produktionsverfahren hergestellt sein. Zudem kann es auch günstig sein, die Leuchtkappe 33 diffus milchig oder milchig/farbig fluoreszierend einzufärben, um die Lichtdurchlässigkeit zu reduzieren, wodurch ein Eigenleuchten der Leuchtkappe 33 sowie eine gleichmäßige und noch intensivere Ausleuchtung erzielt wird. Eine optimal helle und gleichmäßige Ausleuchtung kann zudem dadurch erreicht werden, dass sowohl die Leuchtkuppe 14 des Druckstücks 10 als auch die Leuchtkappe 33 des Betätigungsvorsatzes 27 entsprechend der Licht- bzw. Farbwellenlänge der Leuchtdiode 18 eingefärbt sind.Like the light cap 14, the light cap 33 consists of one translucent material and covers the light cap 14 in one short distance. The inner side 41 of the light cap 14 facing the Luminous cap 33 can also have a fine-pearled structure. This structure can be designed so that a multitude of small pear-shaped elevations and a multitude of small troughs alternating directly next to each other lie so that the inside 41 is finely roughened. This fine-roughened inside structure can be essentially the same as the fine-roughened internal surface structure the light cap 14 executed and according to the same production process be made. It can also be cheap, the light cap 33 diffuse milky or milky / colored fluorescent to color the To reduce light transmittance, which makes the light cap illuminate by itself 33 as well as an even and more intensive illumination becomes. Optimally bright and even illumination can also be achieved achieved that both the light cap 14 of the pressure piece 10 as also the light cap 33 of the actuator 27 according to the Light or color wavelength of the light emitting diode 18 are colored.
