Description

Für eine Reihe von Einsatzgebieten erweist es sich als notwendig, daß Kippschalter wasserdicht bzw. staubdicht ausgeführt sein müssen. In dem DE-GM 18 04 987 wird ein Vorschlag für eine wasserdichte Lagerung des Kipphebels an dem Gehäusedeckel eines Schalters gemacht. Ein anderer Vorschlag für eine derartige Dichtung läßt sich der DE-GM 71 09 985 entnehmen. Eine weitere an diese Schalter gerichtete Forderung besteht darin, daß sie eine Leuchtanzeige besitzen sollen, die zum einen das Finden des Schalters bei Dunkelheit (Suchfunktion) erleichtern soll und/oder den Schaltzustand des Kippschalters bzw. die mit dem Kippschalter geschaltete Funktion (Funktionsanzeige) anzeigen soll.For a number of application areas, it proves necessary that toggle switches are waterproof or dustproof have to be. In DE-GM 18 04 987 a proposal for a waterproof mounting of the rocker arm on the housing cover made a switch. Another proposal for one Seal can be found in DE-GM 71 09 985. A another requirement addressed to these switches is that they should have a light indicator, which on the one hand Make it easier to find the switch in the dark (search function) should and / or the switching state of the toggle switch or with Show the function switched on the toggle switch (function display) should.

In der DE-OS 30 24 510 ist dazu der Vorschlag gemacht, eine Glühlampe in einer gesonderten Kammer des Gehäuses anzuordnen, die von der durch die Schaltkontakte genutzten Kammer abgetrennt ist. Dabei ist die Beleuchtung nur bedingt vor Umwelteinflüssen geschützt, während andererseits sich für das Gehäuse eine vergleichsweise komplizierte Form ergibt.In DE-OS 30 24 510 the proposal is made, one To place the light bulb in a separate chamber of the housing, separated from the chamber used by the switch contacts is. The lighting is only partially conditional on environmental influences protected while, on the other hand, the case results in a comparatively complicated shape.

Die Erfindung geht daher aus von einem Schalter der sich aus dem Oberbegriff des Anspruchs 1 ergebenden Gattung, wie er z.B. aus der US-A-4 340 791 bekannt ist. Aufgabe der Erfindung ist es, einen derartigen Schalter weiter zu verbessern, indem die Form des Gehäuses vereinfacht und die Leuchtkörper besser vor Umwelteinflüssen geschützt werden.The invention is therefore based on a switch the preamble of claim 1 resulting genus, as he e.g. is known from US-A-4,340,791. task the invention is to further improve such a switch, by simplifying the shape of the housing and the Luminous bodies are better protected from environmental influences.

Die Aufgabe wird durch die sich aus dem Anspruchs 1 ergebende Merkmalskombination gelöst. Die Erfindung besteht im Prinzip also darin, die Leuchte selbst mit in die geschlossene Kammer aufzunehmen und das Gehäuse selbst mit einem geeigneten Fenster zu versehen, durch welches der Lichtstrom in den Innenraum der Taste gelangen kann, wo er dann in der üblichen Weise am Boden der Taste angebrachte Symbole oder Fenster ausleuchtet, die zur Information des Bedienungspersonals dienen.The task is characterized by the Resulting combination of features solved. The invention basically consists in including the lamp itself in the closed chamber and the housing itself provided with a suitable window through which the Luminous flux can get into the interior of the button, where it then symbols attached to the bottom of the button in the usual way or window illuminates for the information of the operating personnel to serve.

Um den von dem Leuchtkörper abgegebenen Lichtstrom möglichst weitgehend durch das Gehäuse in den Tastenraum abstrahlen zu können, empfiehlt sich in Weiterbildung der Erfindung die Merkmalskombination nach Anspruch 2. Dieses Merkmal ist natürlich auch bei Verwendung mehrerer Leuchten in dem Schalter und auch bei mehreren Leuchten für eine Taste anwendbar. Die angegebene Konstruktion ist darüberhinaus noch sehr platzsparend und schafft durch die steilen seitlichen Domwände zusätzliche Abdichtungsmöglichkeiten, wie weiter unten noch erläutert wird.To the luminous flux emitted by the filament, if possible radiate largely through the housing into the key area can, is recommended in a further development of the invention Combination of features according to claim 2. This feature is natural even when using multiple lights in the switch and Can also be used for several lights for one button. The specified Construction is also very space-saving and creates additional ones thanks to the steep side walls of the cathedral Sealing options, as explained below becomes.

Um eine kompliziertere Gießform zu vermeiden und beispielsweise bei der Verwendung mehrerer Leuchtkörper die Funktionsanzeige und/oder Suchanzeige durch bloßen Ausbau oder gedrehten Einbau der Tastenkappe bedarfsweise einsetzen zu können, empfiehlt sich in Weiterbildung der Erfindung die Merkmalskombination nach Anspruch 3.To avoid a more complicated mold and for example the function display when using multiple illuminants and / or search ad by mere removal or Use the rotated installation of the key cap if necessary can, is recommended in a further development of the invention Combination of features according to claim 3.

Um einen starken Helligkeitsunterschied bei der Funktionsbeleuchtung in Abhängigkeit von der geschalteten Funktion zu erhalten, empfiehlt sich in Weiterbildung die Merkmalskombination nach Anspruch 4. Danach kann ein mit der Kappe und mit der Taste verbundener Lichtleiter zum einen eng in die Nähe des zugehörigen Leuchtfensters am Gehäuse und damit in die Nähe des Leuchtkörpers geführt werden, zum anderen aber durch die Schwenkbewegung der Taste von dem Leuchtkörper entfernt werden. Dabei läßt sich der Lichtleiter so anordnen, daß durch die Schwenkbewegung gleichzeitig auch der Eintrittswinkel des Lichtes in dem einen Fall in eine zur Übertragung besonders günstige und in dem anderen Fall zur Übertragung besonders ungünstige Lage gebracht werden kann.A strong difference in brightness in functional lighting depending on the switched function the combination of features is recommended in further training according to claim 4. Then one with the cap and light guide connected with the button on the one hand closely into the Close to the associated light window on the housing and thus in the proximity of the filament, but on the other removed from the filament by the pivoting movement of the button will. The light guide can be arranged so that due to the swivel movement, the entry angle at the same time of the light in one case into one for transmission in particular cheap and in the other case for transmission especially unfavorable location can be brought.

Eine für die zuletzt genannten Forderungen besonders günstige Ausgestaltung für den Lichtleiter läßt sich den Merkmalen nach Anspruch 5 entnehmen. Um an der dem Betrachter zugewandten Fläche der Taste bzw. der Kappe einen besonders stark leuchtenden Lichtanzeigebereich zu erhalten, empfiehlt sich in Weiterbildung der Erfindung die Merkmalskombination nach Anspruch 6. Danach ist der Lichtleiter direkt durch den Boden der Kappe geführt, so daß sein Ende für den Betrachter sichtbar ist. Der Betrachter kann somit den von dem Ende des Lichtleiters abgegebenen Lichtstrom direkt wahrnehmen. Dabei kann der Lichtleiter auch die Seitenkontur eines Symbols haben, so daß dieses Symbol dann im entsprechenden Schaltzustand sehr stark leuchtet.A particularly favorable one for the latter demands Design for the light guide can be based on the features Remove claim 5. In order to face the viewer The surface of the button or cap is particularly bright To maintain the light display area is recommended in further training the invention, the combination of features according to claim 6. Then the light guide is directly through the bottom of the cap led so that its end is visible to the viewer. Of the The viewer can thus see the output from the end of the light guide Perceive luminous flux directly. The light guide can also have the side outline of a symbol, so that this The symbol is then very strong in the corresponding switching state shines.

Um, wie schon erläutert, den in den Lichtleiter übergehenden Lichtstrom in Abhängigkeit von der Lage der Kipptaste stark ändern zu können, empfiehlt sich in Weiterbildung der Erfindung die Merkmalskombination nach Anspruch 7. Um einen zusätzlichen Schutz auch im Anschlußbereich des Schalters zu erhalten, empfiehlt sich in Weiterbildung der Erfindung die Merkmalskombination nach Anspruch 8. Dabei ist der Grundkörper relativ tief in den Innenraum des Gehäuses eingeschoben oder anders ausgedrückt, die Seitenwände des Gehäuses sind über die Seitenfläche der Grundplatte heruntergezogen, um diese seitlich gegen Umwelteinflüsse zu schützen.To, as already explained, the transition into the light guide Luminous flux strongly dependent on the position of the rocker switch To be able to change is recommended in further development of the invention the combination of features according to claim 7. To an additional To receive protection in the connection area of the switch, In a further development of the invention, the combination of features is recommended according to claim 8. Here is the basic body inserted relatively deep into the interior of the housing or in other words, the side walls of the case are over the Side surface of the base plate pulled down to the side protect against environmental influences.

Zusätzliche Schutzmaßnahmen können darin bestehen zu verhindern, daß Schadstoffe über die Seitenflächen der Steckkontakte eines in den Anschluß des Schalters einzusteckenden Steckers gelangen. Dazu empfiehlt sich in Weiterbildung die Merkmalskombination nach Anspruch 9. Dabei werden die Steckkontakte des einzusteckenden Steckers sehr sorgfältig voneinander isoliert, was durch entsprechendes Dichtmaterial oder durch Eingießen der Steckkontakte in den Stecker geschehen kann. Dabei kann zusätzlich oder wahlweise auch die Außenkontur des Stekkers gegenüber den heruntergeführten Seitenwänden des Gehäuses durch eine entsprechende Dichtleiste abgedichtet werden, so daß weder Schmutz noch Feuchtigkeit zu den vorzugsweise schneidenförmigen Steckkontakten des Schalters gelangen kann.Additional protective measures can be to prevent that pollutants on the side surfaces of the plug contacts of a plug to be inserted into the connection of the switch reach. The combination of features is recommended in further training according to claim 9. The plug contacts of the plug to be inserted, very carefully insulated from each other, what by appropriate sealing material or by pouring the plug contacts can happen in the plug. Here can additionally or alternatively also the outer contour of the connector opposite the lowered side walls of the housing be sealed by an appropriate sealing strip, so that neither dirt nor moisture is preferred to the cutting-edge plug contacts of the switch can reach.

Um zu verhindern, daß sich etwa Staub oder Feuchtigkeit auf die Frontfläche des Gehäuses setzen kann und die Lichtdurchlässigkeit der Gehäusefenster bzw. die Dichtung der Taste im Gehäuse negativ beeinflußt, empfiehlt sich in Weiterbildung der Erfindung die Merkmalskombination nach Anspruch 10. Dabei sind in der Frontfläche des Gehäuses Aufnahmeräume vorgesehen, welche die seitlichen Blenden bei der Kippbewegung der Taste einschwenken können. Seitenwände derartiger Räume können beispielsweise durch die Seitenwände der weiter oben beschriebenen Gehäuseausbuchtungen gegeben sein, die zur Aufnahme der Leuchtkörper dienen. Bei eingetauchter Blende ergibt sich somit für Staub oder Wasser ein schwer zu überwindendes Labyrinth. Gleichzeitig kann der Aufnahmeraum zum Sammeln von Schmutz oder Feuchtigkeit dienen, so daß diese nicht zu den hochliegenden Fenstern der Frontfläche des Gehäuses gelangen können.To prevent dust or moisture from accumulating can put the front surface of the case and the translucency the housing window or the seal of the button in the Housing negatively affected, is recommended in further training the invention, the combination of features according to claim 10 are provided in the front surface of the housing, which the side panels when the button is tilted can swing in. Side walls of such rooms can for example through the side walls of those described above Housing bulges must be given to accommodate the Serve illuminants. This results with a submerged orifice a labyrinth that is difficult to overcome for dust or water. At the same time, the recording space for collecting Dirt or moisture are used so that they do not become high windows of the front surface of the housing can.

Eine zusätzliche Maßnahme zum Freihalten der Frontfläche des Gehäuses kann in den Merkmalen nach Anspruch 11 bestehen. Dabei überzieht die Taste die Frontfläche des Gehäuses wie ein Schirm.An additional measure to keep the front surface of the Housing can consist in the features of claim 11. Here the button covers the front surface of the housing like a Umbrella.

Wie weiter oben schon erläutert, ist der erfindungsgemäße Schalter nicht nur zur Aufnahme eines einzigen Leuchtkörpers, sondern auch zur Aufnahme von zwei oder mehr Leuchtkörpern geeignet. Soweit man zwei Leuchtkörper verwendet, empfiehlt sich in Weiterbildung der Erfindung die Merkmalskombination nach Anspruch 12. Danach ist es auch möglich, unterschiedliche Aufgaben mit dem konstruktionsgemäß gleichen Schalter dadurch zu lösen, daß die Taste in unterschiedlichen Stellungen auf den Schalter bzw. die Tastenkappe auf dem Betätiger aufgerastet wird.As already explained above, is the invention Switch not only for holding a single lamp, but also to accommodate two or more light sources suitable. As far as two lamps are used, it is recommended the combination of features in a development of the invention according to claim 12. Thereafter, it is also possible to use different Tasks with the same switch according to the design to solve that the button in different positions the switch or key cap snapped onto the actuator becomes.

Um sicherzustellen, daß der zweite Leuchtkörper eine Suchfunktion stets gut erfüllt, wird in Weiterbildung der Erfindung die Merkmalskombination nach Anspruch 13 vorgeschlagen. Danach sind drei unabhängig von der Schalterstellung im wesentlichen miteinander fluchtende durchsichtige Körper vorgesehen, wobei der erste als Fenster in der Gehäusefront, der zweite als Durchbrechung oder Fenster in dem Betätiger und der dritte als lichtdurchlässiges Symbol oder ebenfalls einfaches, unter Umständen farbig angelegtes Fenster ausgestaltet sind.To ensure that the second filament has a search function always well met, is in further development of the invention the combination of features proposed according to claim 13. After that, three are independent of the switch position essentially transparent bodies aligned with one another provided, the first as a window in the front of the housing, the second as an opening or window in the actuator and the third as a translucent symbol or also simple, under certain circumstances designed colored window are.

Die vorliegende Beschreibung geht aus von der DE-OS 30 24 510. Es werden somit nur Merkmale beschrieben, die gegenüber dieser Beschreibung neu und für die vorliegende Erfindung wesentlich sind. Der Schalter nach Fig. 1 besitzt ein Gehäuse 1, dessen angegossenen Seitenwände 2 weit heruntergezogen sind und somit zum Schutz der Anschlußleiste des Grundkörpers 3 dienen. Für die Erfindung besonders wichtig ist, daß das Gehäuse an seinem in Fig. 1 oberen Ende eine durchgehende Frontwand 4 besitzt, die notwendigerweise nur in einem kleinen, sorgfältig abgedichteten Bereich unterbrochen ist, in dem eine Verlängerung der Taste 5 in den Innenraum 6 des Gehäuses 1 ragt.The present description is based on DE-OS 30 24 510. Thus, only features are described that are compared to this Description new and essential to the present invention are. 1 has a housing 1, the molded side walls 2 are pulled down far and thus serve to protect the terminal block of the base body 3. For the invention is particularly important that the housing on his 1 has a continuous front wall 4 in FIG. 1, which are necessarily only in a small, carefully sealed Area is interrupted in which an extension the button 5 protrudes into the interior 6 of the housing 1.

Der Grundkörper 3 ist von unten her in das Gehäuse 1 eingeschoben und mit diesem verrastet. Durch den Grundkörper und mit diesem vergossen, ragen Kontaktmesser 7, die in an sich bekannter Weise sowohl mit den ortsfesten als auch den beweglichen Kontaktstücken eines Wippkontakts verbunden sind. Die Kontaktmesser sind darüber hinaus noch in geeigneter Form mit zwei Leuchtkörpern 8 und 9 verbunden, wobei der Leuchtkörper 8 zur Funktionsbeleuchtung und der Leuchtkörper 9 zur Suchbeleuchtung dient. Die Lampen sind dabei in mit dem Gehäuse verbundenen Fassungen gehalten. Damit können zum einen die Anschlußleitungen selbst zur Halterung der Leuchtkörper 8,9 dienen. Die Fassungen können aber auch zwischen die Seitenwände zweier Ausbuchtungen 10,11 der Frontwand 4 des Gehäuses 1 eingeklemmt sein. Die Arbeitsweise der Schaltstücke des Schalters entspricht der des in der DE-OS 30 24 510 beschriebenen Schalters und wird daher an dieser Stelle nicht nochmals wiederholt.The base body 3 is inserted into the housing 1 from below and locked with this. Through the body and shed with this, contact knife 7 protrude, which in itself known way with both the stationary and the mobile Contact pieces of a rocker contact are connected. The Contact knives are also in a suitable form two luminous elements 8 and 9 connected, the luminous element 8 for functional lighting and the luminous element 9 for search lighting serves. The lamps are connected to the housing Versions held. On the one hand, this allows the connecting lines even serve to hold the luminous body 8.9. The frames can also be between the side walls two bulges 10, 11 of the front wall 4 of the housing 1 are clamped be. The operation of the contact pieces of the switch corresponds to that of the switch described in DE-OS 30 24 510 and will therefore not be repeated here.

Für die Erfindung besonders wichtig ist es, daß die beiden Leuchtkörper 8,9 in den Innenraum des Gehäuses 1 angeordnet und von der durchgehenden Frontwand 4 abgedeckt werden. Damit nun der von den Leuchtkörpern 8,9 abgegebene Lichtstrom auch zur und durch die Taste 5 glangen kann, ist die Frontwand 4 mit zwei Fenstern 12,13 versehen, die kugelförmig gewölbt, durchsichtig und mit dem Gehäuse 1 vergossen sind. In der Frontwand ist die Taste 5 in an sich bekannter Weise (siehe DE-OS 30 24 510 oder DE-AS 12 12 616 bzw. DE-GM 18 04 987) abgedichtet gelagert. Dabei setzt sich die Taste 5 aus einem-Betätiger 14 und einer Kappe 15 zusammen, wobei die Kappe 15 auf den Betätiger 14 aufgerastet ist. Durch die Teilung der Taste 5 ergibt sich eine vereinfachte Gießform sowie die Möglichkeit durch verdrehtes Aufsetzen der Kappe 15 auf den Betätiger 14 den erfindungsgemäßen Schalter für andere Schaltaufgaben einzusetzen.It is particularly important for the invention that the two Luminous body 8.9 arranged in the interior of the housing 1 and be covered by the continuous front wall 4. In order to now the luminous flux emitted by the luminous elements 8.9 can glow to and through the button 5 is the front wall 4 provided with two windows 12, 13 which are spherically curved, are transparent and cast with the housing 1. In the The front wall is the key 5 in a manner known per se (see DE-OS 30 24 510 or DE-AS 12 12 616 or DE-GM 18 04 987) stored sealed. Key 5 is made up of one actuator 14 and a cap 15 together, the cap 15 is snapped onto the actuator 14. By dividing the Key 5 results in a simplified mold and the possibility by twisting the cap 15 onto the actuator 14 the switch according to the invention for other switching tasks to use.

Besonders vorteilhaft für den Schalter sind die durch die Seitenwände 2 des Gehäuses und den Seitenwänden der Ausbuchtungen 10,11 in der Frontwand gebildeten sackartigen Aufnahmeräume 17,18, da hier möglicher Staub oder mögliche Feuchtigkeit an der Außenfläche der Frontwand 4 gesammelt werden kann. Gleichzeitig können zwei an den Betätiger 14 seitlich angesetzte Blenden 18,19 beim Schwenken der Taste 5 mit ihren Enden in die Aufnahmeräume 16,17 eintauchen und so den Weg für Staub und Wasser zu der Oberfläche der Frontwand 4 versperren. Hierdurch werden zusätzlich die Fenster 12,13 und die Dichtung 20 der Taste 5 gegenüber dem Gehäuse 1 frei von Verschmutzung gehalten. Dabei können die Aufnahmeräume 16,17 auch untereinander durch eine umlaufende Nut miteinander verbunden sein, in die dann eine die Blenden 18,19 miteinander verbindende umlaufende Wand eintaucht.The side walls are particularly advantageous for the switch 2 of the housing and the side walls of the bulges 10,11 sack-like receiving spaces formed in the front wall 17.18, because here possible dust or possible moisture the outer surface of the front wall 4 can be collected. At the same time can two attached laterally to the actuator 14 Apertures 18,19 when pivoting the button 5 with its ends in immerse the recording rooms 16, 17 and thus the way for dust and block water to the surface of the front wall 4. Hereby the windows 12, 13 and the seal 20 the button 5 relative to the housing 1 free of dirt held. The receiving spaces 16, 17 can also be with one another be connected to each other by a circumferential groove, in which then connects the diaphragms 18, 19 with one another Immersed in the wall.

Mit der Kappe 15 kann ein Lichtleiter 21 verrastet oder vergossen sein. Das Lichtleiterende 22 bildet ein Fenster in der Oberfläche der Kappe 15, welches sehr hell ausgeleuchtet werden kann. Die Kontur des Lichtleiterendes 22 kann gleichzeitig auch als Symbol ausgestaltet sein. Der Schaft 23 des Lichtleiters geht über in eine Schale 24, die das gewölbte Fenster 12 in der Frontwand 4 umgreift und so den dieses Fenster durchdringenden Lichtstrom aufnimmt und über den Schaft 23 an das Lichtleiterende 22 weitergibt. Während in der in Fig. 1 gezeigten Lage der Lichtübergang von dem Fenster 12 zu der Schale 24 und damit zu dem Lichtleiter 21 sehr leicht ist, ist umgekehrt bei einer in Fig. 1 nicht dargestellten zweiten Kippstellung der Taste 5 die Schale von dem Fenster 12 abgehoben und im Winkel zu dieser schräg gestellt. Damit kann das von dem Fenster 12 kommende Licht kaum noch in die Schale 24 eintreten, wodurch der Bedienungsperson aufgrund des dunklen Lichtleiterendes 22 die in Fig. 1 nicht dargestellte Schalterstellung angezeigt wird.With the cap 15, a light guide 21 can be locked or potted be. The light guide end 22 forms a window in the Surface of the cap 15, which are illuminated very brightly can. The contour of the light guide end 22 can be simultaneously also be designed as a symbol. The shaft 23 of the light guide goes over into a bowl 24, which is the arched window 12 engages in the front wall 4 and so this window penetrating luminous flux and receives via the shaft 23 the light guide end 22 passes on. While in the in Fig. 1st shown location of the light transition from the window 12 to the Shell 24 and thus to the light guide 21 is very light vice versa in a second, not shown in Fig. 1 Tilting position of the key 5, the shell is lifted off the window 12 and at an angle to this. So that can Light coming from the window 12 hardly enters the bowl 24 occur, causing the operator due to the dark Optical fiber end 22, the switch position not shown in Fig. 1 is shown.

Um dem Bedienungspersonal bei Dunkelheit aber gleichwohl die Lage des Schalters anzeigen zu können, dient der zweite Leuchtkörper 9, dessen Strahlung über das Fenster 13 und eine Ausnehmung 25 (die auch als Fenster ausgestaltet sein kann) im Betätiger 14 sowie ein lichtdurchlässiges Fenster 26 in der Kappe 15 zum Betrachter hin gelangen kann. Das Fenster 26 kann die Kontur eines Symbols haben und in die Kappe 15 eingegossen sein oder aber auch durch eine entsprechende Schwächung des Fensterbereiches 26 lichtdurchlässig sein. Insbesondere empfiehlt es sich aber, die Innenfläche der Kappe 15 durch einen weißen Belag oder eine eingespritzte weiße Schicht, die gleichzeitig noch als Fenster 26 dienen kann, reflektierend auszugestalten.To the operating personnel in the dark but nevertheless the The second is to be able to display the position of the switch Luminous body 9, its radiation through the window 13 and a Recess 25 (which can also be designed as a window) in the Actuator 14 and a translucent window 26 in the Cap 15 can reach the viewer. The window 26 can have the outline of a symbol and poured into the cap 15 be or by a corresponding weakening of the Window area 26 be translucent. In particular recommends but it, the inner surface of the cap 15 by a white coating or an injected white layer that can simultaneously serve as a window 26, reflective to design.

Fig. 2 zeigt die Möglichkeit der Ausgestaltung eines zur Abdichtung des Schalters gemäß Fig. 1 geeigneten Steckers. Dabei kann der Stecker an dem Steckergehäuse 29 seitlich vorspringende Laschen 30,31 aufweisen, die zum einen in Verbindung mit den Seitenwänden 2 für eine Dichtung zwischen Stecker 28 und der Anschlußleiste des Schalters sorgen und zum anderen eine Verrastung des Steckers 28 in dem Schaltergehäuse 1 ermöglichen. Die Aufnahmekontakte 32 bis 37 können zur verbesserten Dichtung entweder in das Gehäuse 29 eingegossen oder deren Umgebung durch eine Dichtmasse 33 ausgegossen sein.Fig. 2 shows the possibility of designing a seal of the switch shown in FIG. 1 suitable connector. Here can the connector on the connector housing 29 laterally projecting Have tabs 30,31, on the one hand in connection with the side walls 2 for a seal between connector 28 and the terminal block of the switch and the other one Allow locking of the plug 28 in the switch housing 1. The receiving contacts 32 to 37 can be improved Seal either poured into the housing 29 or their Environment poured out by a sealant 33.

Bei der symmetrischen Anordnung der Leuchtkörper 8,9 ist insbesondere günstig, daß in der einen Tastenstellung bei auf der Frontwand 4 aufsitzendem Lichtleiter 24 die eingeschaltete Funktion am Lichtleiterende 22 besonders deutlich angezeigt wird. In der anderen Stellung dagegen ist durch das Schwenkendes Fensters 26 zu dem Leuchtkörper 9 hin im ausgeschalteten Zustand der Funktionsbeleuchtung die Suchbeleuchtung besonders gut zu erkennen. Fig. 3 zeigt, wie weiter oben schon erläutert, daß die Blenden 18,19 durch seitliche Wände 38,39 zu einer umlaufenden Wand ausgestaltet werden. Entsprechendes gilt für die Aufnahmeräume 16,17, die, wie aus Fig. 3 ersichtlich, in Längsrichtung des Schalters miteinander verbunden sein können, so daß eine umlaufende Nut 40 entsteht, in die die umlaufende Wand eintaucht.In the case of the symmetrical arrangement of the luminous elements 8, 9 is particularly important favorable that in one key position on the Front wall 4 seated light guide 24 the on Function at the end of the light guide 22 displayed particularly clearly becomes. In the other position, however, is due to the swiveling end Window 26 to the filament 9 in the off Condition of the functional lighting, the search lighting especially clearly visible. 3 shows, as already explained above, that the panels 18,19 through side walls 38,39 a circumferential wall can be designed. Corresponding applies to the receiving spaces 16, 17 which, as can be seen from FIG. 3, connected to each other in the longitudinal direction of the switch can be so that a circumferential groove 40 is formed in the dips the surrounding wall.
