Description

Die Erfindung bezieht sich auf einen elektrischen Tastschalter mit einer Betätigungswippe, die ein Schriftfeld aufweist. Der Tastschalter kann Teil einer Tasteranordnung mit mehreren solcher Tastschalter sein.The invention relates to an electrical push button switch with an operating rocker, which has a title block. The key switch can be part of a key arrangement be with several such push buttons.

Tasteranordnungen mit beschriftbaren, streifenförmigen Bedienflächen werden vorzugsweise so z.B. an einer Wand montiert, daß die Schriftzeilen horizontal verlaufen, wobei die Betätigungswippe um eine vertikale Achse schwenkt. Es sind Anordnungen bekannt, bei denen ein Rahmen, der mehrere Taster umgibt, ein Schriftfeld trägt, oder bei denen die Tasterwippen ganzflächig oder auf Teilflächen Schriftfelder haben. Solche Tasteranordnungen werden insbesondere zur Bedienung elektronischer Installationsgeräte verwendet. Tasteranordnungen mit beschriftbaren Wippen sind beispielsweise aus G 93 05 822 und G 94 06 434 bekannt.Button arrangements with inscribable, strip-shaped control surfaces are preferred so e.g. mounted on a wall so that the characters run horizontally, the actuating rocker pivots about a vertical axis. They are orders known, in which a frame that surrounds several buttons, a title block bears, or where the pushbuttons cover the entire surface or partial areas of text fields to have. Such button arrangements are particularly electronic to operate Installation devices used. Button arrangements with inscribable rockers are known for example from G 93 05 822 and G 94 06 434.

Nachteilig ist bei den bekannten Tastern, daß eine Beschriftung nur bei vorhandenem Umgebungslicht lesbar ist, da keine Eigenbeleuchtung vorhanden ist.A disadvantage of the known buttons that labeling is only available Ambient light is legible because there is no self-illumination.

Der Erfindung liegt die Aufgabe zugrunde, einen elektrischen Tastschalter anzugeben, dessen Betätigungswippe mit einem beleuchtbaren Schriftfeld versehen ist und wobei eine weitgehend gleichmäßige Hinterleuchtung des Schriftfelds gegeben ist.The invention has for its object to provide an electrical push button switch, the rocker is provided with an illuminated text field and with a largely uniform backlighting of the text field.

Diese Aufgabe wird durch einen Tastschalter mit den im Anspruch 1 angegebenen Merkmalen gelöst. This object is achieved by a push button switch with the specified in claim 1 Features resolved.

Bei diesem Taster wird mittels eines Lichtleiterkeils erreicht, daß trotz nahezu punktförmiger Lichteinleitung durch eine lichtemittierende Diode LED eine weitgehend gleichmäßige Hinterleuchtung des gesamten Schriftfelds gegeben ist.This button is achieved by means of a fiber optic wedge, that despite almost punctiform light introduction by a light-emitting diode LED a largely uniform backlighting of the entire text field is given.

Als vorteilhafte Ausgestaltung wird vorgeschlagen, zusätzlich eine Statusanzeige mittels einer weiteren lichtemittierenden Diode LED zu schaffen, deren Licht mittels eines Lichtleiterelements zur Wippenoberfläche geführt wird, und außerdem einen Trennsteg an der Wippenunterseite vorzusehen, mit dem eine gegenseitige Beeinflussung der Beleuchtungseinrichtungen vermieden wird.A status display is also proposed as an advantageous embodiment to create by means of a further light-emitting diode LED, the light of which means a light guide element is guided to the rocker surface, and also one Separator to be provided on the underside of the rocker, with which a mutual influence the lighting equipment is avoided.
