In a matt keyboard having elastically deformable bellows (4) and conductor tracks (3) which can be electrically connected in pairs by push-button pressure, by being placed on a contact stamp (5), the number of contact functions per push-button (10) is increased by mechanical allocation of a maximum of three bellows (4) and corresponding contact regions (2) on the printed-circuit board (1). A pressure distributor (9) is provided as a mechanical compensating element between the push-buttons (10) and the associated bellows (4). Application: keyboards for telecommunications terminal equipment. <IMAGE>
