Abstract

The ram (S) of the key cap (TK) is designed as a straight hollow cylinder with a circular cross-section, on whose outer side there are formed two diametrically opposite axial guide webs (FST) and two diametrically opposite wall tongues (WZ) are exposed on its end (SE), in each case by two axial wall cut-outs (WE). On their free ends, the wall tongues (WZ) are each provided with a hook catch (HK) projecting radially outwards. <IMAGE>
