Abstract:
A glass keyboard comprising a keyboard surface (4) made from a flexible thin glass pane (2) and having a marginal area (20) and at least one carrier material pane (6), the flexible glass and carrier material panes (2, 6, respectively) being provided on respective faces facing each other with an electroconductive layer (8, 10, respectively), 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) substantially at a localized area of pressure application, the carrier material pane (6) being slightly larger than the flexible thin glass pane (2) such that a marginal area (28) of the carrier material pane (6) protrudes on all sides beyond the marginal area (20) of the thin glass pane (2), and the marginal area (20) of the thin glass pane (2) is glued to the marginal area (28) of the carrier material pane (6) by means of adhesive acting as said spacer (12) for maintaining the electroconductive layers (8, 10) of the respective flexible glass and carrier material panes (2,6, respectively) normally spaced from each other.
