<p>The control surfaces (11) are formed via rib formations (10) on at least one of the key edges (5,6), the position of which within the key thickness determines the variations. The key has rib formations which are formed by a through, swung control rib on the key edges (5,6). Between the rib formations run inclined connecting sections (12) which are narrower than the rib formations. The rib formations are arranged on the key edges without connecting sections. The control rib or the first rib formation is arranged centrally on the key point (9). The first rib formation runs inclinedly in the direction of the key grip (3) opposite to the central longitudinal plane of the key.</p> |
