Abstract
A control board for a dental apparatus contains a control panel (1) having a plurality of key surfaces (2) for the actuation of sensor devices (3) that respond to a force or a change in force. The sensor devices (3), facing toward the operating side, are covered by a thin front plate (4a) of transparent material. The front plate (4a) is provided with an all around, lateral edge (5) that is an integral component part of the front plate (4a) and thus forms a frame (4) that is closed at the front side and surrounds the control panel. At least the front plate (4a) and, preferably, the entire frame (4) is composed of glass.
