Abstract (en)

[origin: DE19810327A1] The glass keyboard has a keyboard surface (4) of a flexible thin glass plate (2) and at least one carrier material plate (6) with electrically conducting layers (8,10) on their facing sides held apart by a distance piece. The electrically conducting layers are brought into contact at the essentially point-shaped pressure loading points when the glass plate is subjected to pressure. The keyboard surface is flat in the edge regions (20) and with a slight convex outward curvature in the switching region. The thin glass plate forming the keyboard surface is stuck to the carrier plate in the deep-drawn state An Independent claim is also included for a method of producing a glass keyboard.
