Device for mechanical Channel display. Door push-button units for televisions with a central tuning button

The innovation relates to a device for mechanical Channel display for pushbutton assemblies on televisions ■ with rotatable central tuning button and program selection pushbuttons, whereby by the program selection pushbuttons respectively an associated clutch can be actuated, by means of which the associated clutch is assigned to the pressed program selection pushbutton Tuning means can be coupled with the central tuning button.

With the well-known so-called drawer button, the entire potentiometer unit is removed from the button panel by pressing a button driven out. Each potentiometer has its tlfeiw oksls us4 its own tuning button, the other Function as push button works.

Individual scales are also used on the flap keys. This is, for example, a 7-way voting unit with central voting in which the individual pushbuttons are designed as flaps, with each flap assigned a potentiometer with a scale and a key slide is. If a scale is now required for tuning, "| so the previously pressed key must be opened

In the viewing window 6 there is provided a marking line 9 parallel to the tuning axis 2, e.g. a red marking line, which serves as a tuning aid. After the voting process, the Central tuning button 1 pushed back again and with it the scale 3 made invisible again.
