Abstract (en)
[origin: EP0478991A2] A holder for keys (1), which are held displaceably against spring force, of a keyboard of electrical apparatuses. The keys are intended to be held in such a manner that they are arranged adjacent to one another, separated in the region of their operating surfaces (11) only by a small air gap. This is achieved in that, internally, the keys (1) have projections (4), which are connected to them integrally and are guided in perforations (5), arranged underneath the keys (1) and in the interior of the telephone station, of the telephone housing (12). The keys (1) furthermore have holding elements (7) which engage behind receptacles (9) arranged in the region of the said perforations (5). <IMAGE>
