OPERATING OR COMMAND ELEMENT - IN PARTICULAR, FOR THE FIELD OF HYGIENE

摘要

The invention relates to an operating or command element (10), comprising a key plate (11) having a substantially flat or slightly curved basic form and having a plurality of surface elevations (12, 13; 20; 22-28), which are formed on the basic form and which can be tactilely sensed by means of a fingertip so that the position of the fingertip on the key plate (11) can be sensed. According to the invention, both in a horizontal and in a vertical installation position of the operating or command element (10), the key plate (11) is 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.
