Abstract: A holding adapter for fixing control and signaling devices, including pushbuttons, on a front plate, includes: a housing having a first recess; and a mounting plate mounted in the housing and having a second recess. The second recess is arranged flush with the first recess so that a control or signaling device is guidable in an axial direction through the two recesses. The mounting plate is displaceable in the axial direction relative to the housing between a first end position and a second end position so as to provide a vertical compensation when the control or signaling device is fixed to the front plate, depending upon a thickness of the front plate.

Abstract: An operating or command element has a key plate having a substantially flat or slightly curved basic form and having a plurality of surface elevations, which are formed on the basic form and which can be tactilely sensed using a fingertip so that the position of the fingertip on the key plate can be sensed. Both in a horizontal and in a vertical installation position of the operating or command element, the key plate can be free of recesses in which liquids can accumulate. Other installation angles are also possible, for example in the case of installation in an inclined console housing.
