Description

Schalterfeld mit wenigstens einem Schalter Switch panel with at least one switch
Technisches GebietTechnical field
Die Erfindung betrifft ein Schalterfeld mit wenigstens einem Schalter, dessen Betätigungstaste in einer Öffnung einer Frontplatte liegt, und mit einem im Bereich der Öffnung der Frontplatte angeordneten, den Schalter umschließenden Gehäuse, das zwischen einer inneren und einer äußeren Umfangswand einen gegen die Frontplatte offenen, lichtdurchlässig abgedeckten Ringspalt zur Aufnahme wenigstens eines Beleuchtungsmittels bildet.The invention relates to a switch panel with at least one switch, the actuation button of which is located in an opening in a front panel, and with a housing which is arranged in the region of the opening of the front panel and surrounds the switch and which, between an inner and an outer peripheral wall, is open to the front panel and is translucent covered annular gap for receiving at least one illuminant.
Stand der TechnikState of the art
Um bei einem Schalter eines Schalterfeldes eine Umfangsbeleuchtung vorzusehen, ist es aus dem Stand der Technik bekannt (DE 3 228 290 A1), die Betätigungstaste des Schalters sowohl teilweise lichtdurchlässig auszubilden als auch rückseitig mit Beleuchtungsmitteln anzustrahlen. Liegt nun die Betätigungstaste auch in einer Öffnung einer lichtundurchlässigen Frontplatte, so ergibt sich eine von der Frontplatte und vom lichtundurchlässigen Teil der Betätigungstaste begrenzte Umfangsbeleuchtung. Nachteilig bei derartigen Schaltern ist jedoch, daß mit einer Freistellung der Betätigungstaste in Betätigungsrichtung die Beleuchtungsmittel mit Abstand zur Betätigungstaste angeordnet werden müssen, was die Helligkeit der Beleuchtung vermindert. Zwar kann dieser Helligkeitsverlust mit leistungsstarken Beleuchtungsmitteln wieder ausgeglichen werden, jedoch kommt dies für kostengünstige Schalter nicht in Frage. Hinzu kommt, daß ein Großteil der Lichtleistung der Beleuchtungsmittel von der lichtundurchlässigen Abdeckung der Beleuchtungstaste zurückgehalten wird, so ohne eine Verwendung von Lichtleitern diese Leistung für die Umfangsbeleuchtung verloren geht. Ein Einsatz von Lichtleitern ist jedoch vergleichsweise kostenintensiv sowie konstruktiv aufwendig. Außerdem sind derartige Schalter aufgrund ihrer Freistellung zwischen der Betätigungstaste und dem Gehäuse für Verschmutzungen der Beleuchtungsmittel anfällig, so daß mit einer stetigen Abnahme der Leuchtkraft der Umfangsbeleuchtung zu rechnen ist. Hinzu kommt, daß aufgrund der Freistellung auch nicht vermieden werden kann, daß andere Schalter beleuchtet werden.In order to provide circumferential lighting for a switch in a switch panel, it is known from the prior art (DE 3 228 290 A1) to make the actuation button of the switch partially translucent and also to illuminate it on the back with lighting means. If the actuation button now also lies in an opening in an opaque front panel, the result is peripheral illumination limited by the front panel and the opaque part of the actuation button. A disadvantage of such switches, however, is that when the actuating button is released in the actuating direction, the lighting means must be arranged at a distance from the actuating button, which reduces the brightness of the lighting. This loss of brightness can be compensated for with high-performance lighting, but this is out of the question for inexpensive switches. In addition, a large part of the light output of the lighting means is held back by the opaque cover of the lighting button, so without the use of light guides this power is lost for the peripheral lighting. However, the use of light guides is comparatively expensive and structurally complex. In addition, such switches are susceptible to contamination of the lighting means due to their release between the actuation button and the housing, so that a steady decrease in the luminosity of the peripheral lighting is to be expected. In addition, because of the exemption, it cannot be avoided that other switches are illuminated.
Darstellung der ErfindungPresentation of the invention
Der Erfindung liegt somit die Aufgabe zugrunde, ein Schalterfeld mit wenigstens einem Schalter der eingangs geschilderten Art so zu verbessern, daß trotz einer Verwendung von leistungsschwachen Beleuchtungsmitteln eine ausreichend helle Umfangsbeleuchtung der Betätigungstaste erzielt werden kann, ohne damit aber einen hohen konstruktiven Aufwand treiben zu müssen. Außerdem soll die Umfangsbeleuchtung vergleichsweise kostengünstig sein sowie hohe Standzeiten erlauben.The invention is therefore based on the object to improve a switch panel with at least one switch of the type described in such a way that, despite the use of low-power lighting means, a sufficiently bright circumferential illumination of the actuation button can be achieved without, however, having to drive a great deal of design effort. In addition, the circumferential lighting should be comparatively inexpensive and allow a long service life.
Die Erfindung löst die gestellte Aufgabe dadurch, daß das Gehäuse mit der äußeren Umfangswand bündig in die Öffnung der Frontplatte eingesetzt ist und mit seiner inneren Umfangswand die Betätigungstaste umschließt und daß die lichtdurchlässige Abdeckung des Ringspalts zwischen innerer und äußerer Umfangswand aus einer sich über die Frontplatte erstreckenden Folie besteht.The invention solves the problem in that the housing is inserted flush with the outer peripheral wall in the opening of the front panel and encloses the actuating button with its inner peripheral wall and that the translucent cover of the annular gap between the inner and outer peripheral wall from a extending over the front panel Foil exists.
Ist das Gehäuse mit der äußeren Umfangswand bündig in die Öffnung der Frontplatte eingesetzt und umschließt seine innere Umfangswand die Betätigungstaste, so kann für eine Umfangsbeleuchtung auf eine aufwendige konstruktive Ausgestaltung der Betätigungstaste verzichtet werden, da ja der Ringspalt mit seinen Beleuchtungsmitteln vom Schalter getrennt in der Öffnung der Frontplatte liegt. So bedarf es aufgrund der fehlenden rückseitigen Beleuchtung keiner lichtundurchlässigen Abdeckung der Betätigungstaste. Au- ßerdem ist mit leistungsschwachen Beleuchtungsmitteln noch eine ausreichende Helligkeit der Umfangsbeleuchtung zu gewährleisten, da bei der Erfindung im Gegensatz zum Stand der Technik einerseits kein Helligkeitsverlust durch einzuhaltende Abstände eintritt und andererseits die gesamte Leuchtkraft der Beleuchtungsmitteln für die Umfangsbeleuchtung verwendet werden kann. Mit einer lichtdurchlässigen Abdeckung des Ringspaltes durch eine sich über die Frontplatte erstreckenden Folie steht den Beleuchtungsmitteln eine in sich abgeschlossene Aufnahme zur Verfügung, womit Verschmutzungen vermieden werden können. Die erfindungsgemäße Umfangsbeleuchtung zeichnet sich daher durch eine hohe Standzeit und geringe Kosten in der Herstellung und im Betrieb aus. Hinzu kommt, daß auf eine Verwendung von Lichtleitern verzichtet werden kann, was insbesondere den gesamten konstruktiven Aufwand für das Schalterfelds verringert.If the housing with the outer peripheral wall is inserted flush into the opening of the front panel and its inner peripheral wall surrounds the actuation button, a complex structural design of the actuation button can be dispensed with for peripheral lighting, since the annular gap with its illuminants is separated from the switch in the opening the front panel. Due to the lack of back lighting, there is no need for an opaque cover for the actuation button. Au- In addition, sufficient brightness of the circumferential lighting is still to be ensured with low-power illuminants, since, in contrast to the prior art, in the invention, on the one hand, there is no loss of brightness due to distances to be maintained and, on the other hand, the entire luminosity of the illuminants can be used for the circumferential illumination. With a translucent covering of the annular gap by means of a film extending over the front plate, the lighting means have a self-contained receptacle, with which contamination can be avoided. The peripheral lighting according to the invention is therefore characterized by a long service life and low costs in production and operation. In addition, there is no need to use optical fibers, which in particular reduces the overall design effort for the switch panel.
Ragt die Betätigungstaste mit einer gewölbten Betätigungsfläche über die Frontplattenoberfläche vor, so ist es einen Benutzer vergleichsweise einfach möglich, den Druckpunkt der Betätigungstaste einzusehen, was das Risiko einer Beschädigung der Folie des Ringspalts noch weiter vermindert. Ist die Betätigungsfläche durch eine sich über das Gehäuse erstreckende, zumindest im Bereich des Ringspalts zwischen innerer und äußerer Umfangswand lichtdurchlässige Schutzfolie zusätzlich abgedeckt, so kann nicht nur eine Verschmutzung des Schalters vermieden werden, sondern es ist auch damit die Festigkeit der Abdeckung des Ringspaltes erhöht.If the actuating button protrudes with a curved actuating surface over the front plate surface, it is comparatively easy for a user to see the pressure point of the actuating button, which further reduces the risk of damage to the film of the annular gap. If the actuating surface is additionally covered by a protective film which extends over the housing and which is translucent at least in the region of the annular gap between the inner and outer peripheral wall, not only can contamination of the switch be avoided, but also the strength of the covering of the annular gap is increased.
Ist das Beleuchtungsmittel und der Schalter auf einer Platine vorgesehen und ragen diese durch Bodenaussparungen in das Gehäuse, so können mit einem Lösen der Platine vom Gehäuse auf einfache und schnelle Weise Wartungsarbeiten durchgeführt werden.If the lighting means and the switch are provided on a circuit board and these protrude through floor recesses in the housing, maintenance work can be carried out in a simple and quick manner by detaching the circuit board from the housing.
Kurze Beschreibung der ZeichnungBrief description of the drawing
In der Zeichnung ist der Erfindungsgegenstand beispielsweise dargestellt. Es zeigen Fig. 1 eine Draufsicht auf einen Teil der Schalttafel ohne Folienabdeckung, Fig. 2 einen Schnitt nach ll-ll der Fig. 1 mit Folienabdeckung und Fig. 3 das erfindungsgemäße Gehäuse des Schalters in einer dreidimensionalen Ansicht.The subject matter of the invention is shown in the drawing, for example. Show it Fig. 1 is a plan view of a part of the control panel without a film cover, Fig. 2 is a section according to II-II of Fig. 1 with film cover and Fig. 3, the housing of the switch according to the invention in a three-dimensional view.
Weg zur Ausführung der ErfindungWay of carrying out the invention
In dem dargestellten Ausführungsbeispiel des erfindungsgemäßen Schalterfelds (Fig. 1), bildet eine Frontplatte 4, beispielsweise aus einem Aluminiumwerkstoff, eine Öffnung 3 aus, in die ein Gehäuse 1 , beispielsweise aus einem Kunststoffwerkstoff, eingesetzt ist. Das Gehäuse 1 schließt mit seiner äußeren Umfangswand 2 bündig mit dieser Öffnung 3 ab und weist zwischen seiner äußeren Umfangswand 2 und seiner inneren Umfangswand 5 einen gegen die Frontplatte 4 offenen Ringspalt 8 auf. In diesen Ringspalt 8 sind mehrere Beleuchtungsmittel 11 eingesetzt, die für eine Umfangsbeleuchtung einer von der inneren Umfangswand 5 umschlossenen Betätigungstaste 6 eines Schalters 12 vorgesehen sind (Fig. 2). Das Ein und Ausschalten der Umfangsbeleuchtung kann beispielsweise mit einer nicht näher dargestellten Steuereinrichtung erfolgen, die den Beleuchtungsmitteln 11 , beispielsweise LED Bausteine, bei einem Betätigen des Schalters 12 elektrische Leistung zuführt. Der Schalters 12 ist also vom Ringspalt 8 durch eine lichtundurchlässige Gehäusewand 5 getrennt, womit kein rückseitiges Beleuchten der Betätigungstaste 6 zu befürchten ist. Es kann daher eine Umfangsbeleuchtung mit einer vergleichsweise scharfen Kontur gewährleistete werden, zumal die gesamte Leuchtkraft der Beleuchtungsmittel 11 ohne Streuverluste der Umfangsbeleuchtung zur Verfügung steht. Um ein vorteilhaftes Abstrahlverhalten der Beleuchtungsmittel 11 zu gewährleisten, ist auch denkbar, daß die das Beleuchtungsmittel 11 umgebenden Seiten des Gehäuses 1 verspiegelt sind. Um Verschmutzungen zu vermeiden ist der Ringspalt 8 mit einer lichtdurchlässigen Abdeckung aus einer sich über die Frontplatte 4 erstreckenden Folie 9 abgedeckt. Dabei hat sich herausgestellt, daß es von Vorteil ist, die Folie 9 nicht nur über den Ringspalt 8 sondern auch bis zur Betätigungstaste 6 randseitig vorstehen zu lassen und gegebenenfalls auch in diesem Überlappungsbereich mit der Betätigungstaste 6 zu verkleben. Damit kann auch der Schalter 12 gegenüber Verschmutzungen geschützt werden. Außerdem kann so der schmale Gehäusesteg zwischen Ringspalt 8 und innerer Umfangswand 5 verdeckt werden.In the illustrated embodiment of the switch panel according to the invention (FIG. 1), a front plate 4, for example made of an aluminum material, forms an opening 3 into which a housing 1, for example made of a plastic material, is inserted. The housing 1 closes with its outer peripheral wall 2 flush with this opening 3 and has an annular gap 8 open towards the front plate 4 between its outer peripheral wall 2 and its inner peripheral wall 5. In this annular gap 8, a plurality of lighting means 11 are used, which are provided for peripheral lighting of an actuation button 6 of a switch 12 enclosed by the inner peripheral wall 5 (FIG. 2). The peripheral lighting can be switched on and off, for example, using a control device (not shown in more detail) which supplies the lighting means 11, for example LED modules, with electrical power when the switch 12 is actuated. The switch 12 is therefore separated from the annular gap 8 by an opaque housing wall 5, so that there is no fear of backlighting of the actuation button 6. A circumferential illumination with a comparatively sharp contour can therefore be guaranteed, especially since the entire luminosity of the illuminating means 11 is available without scattering losses of the circumferential illumination. In order to ensure an advantageous radiation behavior of the lighting means 11, it is also conceivable that the sides of the housing 1 surrounding the lighting means 11 are mirrored. In order to avoid contamination, the annular gap 8 is covered with a translucent cover made of a film 9 extending over the front plate 4. It has been found that it is advantageous to have the film 9 projecting not only beyond the annular gap 8 but also up to the actuation button 6 and, if appropriate, also in this overlap area with the actuation button 6 to glue. The switch 12 can thus also be protected against contamination. In addition, the narrow housing web between the annular gap 8 and the inner peripheral wall 5 can be covered.
Die Betätigungstaste 6 ragt mit ihrer gewölbten Betätigungsfläche über die Frontplattenoberfläche vor, was für den Benutzer des Schalterfeldes auch optisch die Lage des Betätigungstaste 6 anzeigt, so daß auf Kennzeichnungen auf der Folie 9 zum Hinweis auf die Betätigungstaste 6 verzichtet werden kann. Desweiteren ist die Betätigungstaste 6 mit einer sich über das Gehäuse 1 erstreckende, zumindest im Bereich des Ringspalts 8 zwischen innerer und äußerer Umfangswand 2 und 5 lichtdurchlässige Schutzfolie 10 abgedeckt, womit einerseits auf einfache Weise nach einem Fertigen des Schalterfelds die Farbe der Umfangsbeleuchtung bestimmt oder auch verändert werden kann und anderseits auch der Schalter 12 gegenüber Verschmutzungen bzw. Abnutzungen geschützt ist. Diese zusätzliche Folienabdeckung 10 kann beispielsweise im Überlappungsbereich mit der über die Frontplatte gezogenen Folie 9 verklebt sein. Vorstellbar ist aber auch, daß nur eine Folie über die Frontplatte gezogen wird, die aus der Folie 9 und der zusätzlichen Folienabdeckung 10 besteht.The actuating button 6 protrudes with its curved actuating surface over the front panel surface, which also visually indicates the position of the actuating button 6 to the user of the switch field, so that there is no need for markings on the film 9 to indicate the actuating button 6. Furthermore, the actuation button 6 is covered with a protective film 10, which extends over the housing 1 and is translucent at least in the region of the annular gap 8 between the inner and outer circumferential walls 2 and 5, which on the one hand determines the color of the circumferential lighting in a simple manner after the switch field has been produced, or else can be changed and on the other hand, the switch 12 is protected against dirt or wear. This additional film cover 10 can, for example, be glued in the overlap area to the film 9 drawn over the front plate. But it is also conceivable that only one film is drawn over the front panel, which consists of the film 9 and the additional film cover 10.
Die Beleuchtungsmittel 11 und der Schalter 12 sind auf einer Platine 13 mit elektrischen Verbindungen vorgesehen, welche Platine 13 auch Öffnungen für Befestigungszapfen 14 des Gehäuses aufweist. Über dies Befestigungszapfen 14 ist die Platine 13 mit dem Gehäuse 1 fest verbunden sein, was nicht näher dargestellt ist. Bei Wartungsarbeiten ist daher lediglich die Platine 13 vom Gehäuse 1 zu trennen, womit dann die Beleuchtungsmittel 11 bzw. auch der Schalter 12 leicht zugänglich sind. Das Gehäuse 1 wird von der Platine 13 an die Frontplatte 4 des Schalterfelds angedrückt, so daß ein Verrutschen des Gehäuses 1 beim Betätigen des Schalters 12 ausgeschlossen werden kann. Für die Beleuchtungsmittel 11 und den Schalter 12 sind jeweils Bodenaussparungen 15 im Gehäuse 1 vorgesehen (Fig. 3), in diese vorstehend genannte auch ragen. Es muß nicht weiter erwähnt werden, daß die Betätigungstaste 6 bzw. die Umfangsbeleuchtung nicht nur auf eine Kreisform beschränkt ist, sondern daß vielmehr die erfindungsgemäße Umfangsbeleuchtung bei jeglicher Form der Betätigungstaste 6 vorgesehen werden kann. Es ist ja nur dafür der Ringspalt 8 dementsprechend anzupassen. The lighting means 11 and the switch 12 are provided on a circuit board 13 with electrical connections, which circuit board 13 also has openings for fastening pins 14 of the housing. The circuit board 13 is firmly connected to the housing 1 via this fastening pin 14, which is not shown in detail. For maintenance work, therefore, only the circuit board 13 is to be separated from the housing 1, so that the lighting means 11 or the switch 12 are then easily accessible. The housing 1 is pressed by the circuit board 13 onto the front plate 4 of the switch panel, so that the housing 1 cannot slip when the switch 12 is actuated. Floor recesses 15 are provided in the housing 1 for the lighting means 11 and the switch 12 (FIG. 3), into which the above-mentioned also protrude. It need not be mentioned further that the actuation button 6 or the peripheral lighting is not limited to a circular shape, but rather that the peripheral lighting according to the invention can be provided in any form of the actuation button 6. It is only for the ring gap 8 to be adjusted accordingly.
