Abstract:
A glass keyboard comprising a keyboard surface (4) made from a flexible thin glass pane (2) and at least one carrier material pane (6), each pane being provided on opposing faces with an electroconductive layer (8, 10), the opposing electroconductive layers (8, 10) being kept at a distance from each other by a spacer (12), the electroconductive layers (8, 10) touch each other when pressure is applied to the flexible thin glass pane (2) at an essentially localized area of pressure application, the electroconductive layers (8, 10) on the thin glass pane (2) and the carrier material pane (6) being connected with respective conductors (62, 66) which are led out at a side edge of the keyboard surface (4), flexible flat multiple cables (64, 68) being connected respectively with the conductors (62, 66) of the electroconductive layers (8, 10) via contacts (74, 75),the flat multiple cables (64, 68) and the contacts (74, 75) being arranged between the thin glass pane (2) and the carrier material pane (6), and the flat multiple cables (64, 68) are in side-by-side relationship to each other.
