Switch, especially push button or push button switch far Televisions.

The present fire relates to a switch, in particular Push or slide buttons for communications end and / or receiving devices, preferential prices for Ferr. Viewing devices, with devices for selecting and storing several Frequency ranges and benders, whereby for jender setting and possibly also provided for display spindles with traveling nuts are, of which about the former electromechanical or electronic voting elements are adjustable and with one of the Frequency range and bender or »channel display scale assigned to the switch.

In such switches for voting units of televisions lot it is crowned, the otheriautter of the st immpotent iometer of capacitance variation diodes to be provided with a pointer that slides over the display scale. This arrangement is, however, then more Judges jut visible Werin the tune in a station, for example, is to be made in darkened room "

Therefore, the innovation is concerned u _o a. with the task of creating an illuminated display with the purpose of being able to make a comfortable setting even in the dark and to use as few parts as possible when manufacturing the switch <>

This is achieved according to the tariff that on the traveling mother a reflector is provided that illuminates the light beam of the path of the v.aridermutter or the reflector Light source reflected on a display dial. This is a corresponding to the adjustment of the hiking nut on the Display scale moving line or point generated. As the display scale is perpendicular to the spindle adapter Type of display no mechanical aids required to convert the direction of movement of the ..andermut into a vertical line. In addition, a reduction in size can be achieved in a simple manner or improvement of the display scale length can be effected by

Further advantageous details of the firing system are now by way of the drawing illustrated Ausführun ^ sbeiopiels described, "The drawing Z3i ₆ -t only a section of a ochalters"

1 with a G-housing of a push button switch is designated, in dea several spindles 2 are arranged parallel to each other »on The spindle 2 has an axially adjustable nut 3 which is axially adjustable by a projection 5 guided in a slot 4 is secured against twisting »The spindle 2 is secured by a turn = Pushbutton 6 can be actuated or it can be activated by a so-called central tuning button, as is the case with corresponding pushbutton switches used for televisions »can be rotated after pressing pushbutton 6. The spindle 2 karm tuning and / or Be display spindle.

Keuerunssgemiss the inderinu'jter 3 is provided on the top with a reflector 7, through which a light beam illuminating from a light source to a transparent or translucent, ζ .3. back frosted Number ^ igeskala reflected 11 pot at the point of impact of the display scale 11 is then obtained a light stroke or "point 12 ₀

To the light source 8 for reasons of space saving as close as possible to To know to arrange reflector 7 and still have a large display dial length To obtain the reflector is advantageous slightly inclined towards the display scale 11.

The reflector 7 can consist of one piece with the wall nut 3, the surface of which is polished or mirrored or with a reflective part, e.g. a preferably self-adhesive glossy film, is covered. However 3p reflector 7 may be attached to the ".andermutter 3, glued or fastened in any other _y suitable" else be uir must not provided unluitfcelbar to the spindle 2 but can also laterally beyond the traveling nut 3 in the form of a tab or a pointer survive,

The push button and / or rotary button 6 can expediently be at least a position can be rotated independently of the spindle 2, whereby a frequency range switching of an assigned tuning « χ hidden by a cover 9, the »eg the hiking nut 3

equipment prepared and switched or * switched by pressing the same kaun. By causing the switchover Part, e.g. a port set of the key 6, or a mechanical element actuated thereby, can be inserted into the beam path of the Light beam 10, depending on the rotation of the key, a different colored, translucent strip can be introduced shows the color of the light line 12 in each case one The color assigned to the frequency range. Preferably there is an extension on the key which covers the length of the deflector 7 arranged, which has colored longitudinal stripes, one of which depending on the rotation of the button 6 in the light beam 10 between these and the light source 8 and / or the display scale 11 comes.

The arrangement of a transparent part of the Button or this itself is designed to be light-guiding in such a way that the light beam falling on the extension is partly in it is initiated and is visible on the front of the key or its scope ο This key then shows the preselected or « Color assigned to the switched-on frequency range.
