Push or slide key unit with operating pressure indicator

The innovation concerns a push or slide key assembly for the optional setting of different Be = Operating states of electrical and precision engineering devices with operating status display, in particular for Display of the currently switched on waveband of radio receivers and television sets.

The innovation achieves a significant simplification the operating status display device of the above nSher iSÄis leime th push or slide button assembly in that according to the innovation of the operating status file a non-rotatably attached resilient means made of metal or plastic is used, which is in the switching path of the assigned key is provided and that the free end of the resilient means is displaceable through this is that the operating status initial display field is enabled.

An advantageous further development of the innovation is characterized by the fact that the operating status display has several

Keys a common, preferably by punching
manufactured spring sheet metal part is used. This increases the number of individual levers that would otherwise be required.
Segments, slides, bearing bolts, rivets, locking washers, compression and spiral springs practically combined and combined to form a common part made of spring steel sheet.

An exemplary embodiment is given below with reference to FIGS. 1-3 the Heüefüng described. Show it*

Fig. 1 is a side view of a sliding unit «With a pressed slide button,

2 shows the same side view with a printed slide button and ¹

3 that which serves to display the operating status Common spring sheet in plan view.

The common spring plate used to display the operating status has essentially the shape of a comb with a common TJ-shaped web part 1 on which tabs 2 with two different lengths 3 _t k are provided. The common spring sheet metal part is preferably produced by stamping.
