摘要：
In order to allow a high degree of touch-sensor system sensitivity of the sensors even under difficult environmental conditions, in particular low sensitivity to soiling and condensation, of the touch-sensitive operator control apparatus in question without the need for apertures, cutouts or other process steps, the sensors (S1,...) are configured as air capacitors which have a metal plate (M), which is common to all sensors (S1,...), as operator surface, and which, as measurement electrode, each have a sensor area (SM1,...), which sensor areas are arranged at a distance from one another on the first layer of a multilayer printed circuit (LP). An air layer (LU) of specific thickness is configured between the metal plate (M) and first layer of the printed circuit (LP), wherein this distance is determined by a plurality of spacers which are arranged at a distance from one another and are composed of insulating material (D). A shielding (AB) is arranged between third layer (L), which is populated, and first laye
