Moreover, the structure should be simple and the operating principle be diverse applicable. Die Lösung dieser Aufgabe ist gekennzeichnet durch die Verwendung einer Lichtsammelvorrichtung im Gehäuseteil oder im Betätitgungsteil, welche aus einem Körper (Fluoreszenzkörper) besteht, der The solution of this object is characterized by the use of a light collecting device in the housing part or in Betätitgungsteil consisting of a body (fluorescent body) consists of
    • a) aus einem Material mit einem Brechungsindex n> 1 besteht, a) consists of a material having a refractive index n> 1,

Statt einer einzigen Lichtsammelvorrichtung, die im folgenden Fluoreszenzkörper genannt wird, können auch mehrere vorzugsweise verschiedenfarbige Lichtsammelvorrichtungen Verwendung finden. Instead of a single light-collecting device which is hereinafter referred to as fluorescent body, even more preferably differently colored light-collecting devices can be used. Das gilt auch für die in den abhängigen Ansprüchen aufgeführten Merkmale, in denen der Einfachheit haiber im allgemeinen nur von einer Lichtsammelvorrichtung die Rede ist.

With the solution according to the invention, it is possible not only a signal button, but other switching devices such as toggle switches, rotating switches and slide switches or the like, to illuminate. Die Möglichkeit, Licht-insbesondere auch diffuses Licht-zu sammeln und auf definierte Auskoppelbereiche zu konzentrieren, macht das erfindungsgemäß vorgeschlagene Signalelement einem System mit Spiegeln in der Anwendungsbreite weit überlegen und rückt es bezüglich seiner Erkennbarkeit in die Nähe aktiver Signalanzeigen. The possibility of light in particular diffuse light to collect and concentrate on defined Auskoppelbereiche, the signal element proposed by the invention makes a system with mirrors in the application range far superior and moves it relative to its visibility in the vicinity of active signal indicators. Sowohl in der Dämmerung als auch in sehr hellem Umgebungslicht ist die Anzeige gut lesbar, was beispielsweise bei LED's oder Glimmlampen nicht für diesen Weitenbereich zutrifft. Both at dawn and in very bright ambient light, the display is easy to read, which is not the case for example with LEDs or neon lamps for this length range.
