发明名称 Push-button key arrangement having at least one push button for a switching element which can be moved in the push-button direction
摘要 A push-button arrangement having at least one push button for a switching element which can move in the push-button direction, whose push button overhangs a baseplate or the like, as well as a push-button cap which can be guided against a restoring force, contains a pressure element or the like which is to be allocated to a circuit and has a push-button surface, the push button being fitted on a frame of the baseplate, is intended to make possible precise guidance of the push-button cap while at the same time being simple to assemble. For this purpose, on the inside of its push-button cap (29), the push button (30) has at least one frame-like guidance device (32) which rests, such that it can slide, against a frame of the baseplate, a pair of pressure pins (28) or the like, which run at a distance from the guidance device, projecting approximately in the push-button centre from the inside as a pressure element, which pressure pins (28) bound a gap (27) between them. In addition, a bottom plate extends through the frame of the baseplate, which bottom plate is provided with a recess, through which the pressure pin passes, for each pressure pin (28) on the push button (30). <IMAGE>
