Abstract

A plate (1) which protects the keyboard is arranged above a contact foil keyboard (12). Above each key element (16), the plate (1) has a cutout which makes the plate sufficiently resilient in this zone for it to be possible for the key to be actuated properly. Contact foil keyboards can be made vandal-proof with the cover. <IMAGE>
