KEYBOARD PANEL Russian patent published in 2006 - IPC H01H13/70 

FIELD: instrumentation engineering; data input devices for computers, telephone sets, instruments, etc.

SUBSTANCE: proposed keyboard panel is made in the form of single integral-surface metal plate in which marking designations are disposed within plate material and convex sections function as keys capable of elastic sagging under pressure. Plate, 0.10 to 0.20 mm thick, is made of aluminum or titanium alloys with anodized layer on its face painted to form key patterns with marking designations thereon. This plate can be covered with additional anodized layer on its underside in which case contact pads can be made on convex sections of plate in the form of holes in this anodized layer or in the form of conducting material vacuum-evaporated on this anodized layer. Additional anodized layer covering plate underside may have auxiliary panel-grounding-contact made in the form of hole in anodized layer. Copper or nickel can be used for vacuum evaporation.

EFFECT: improved design.
