Abstract
Abstract A print for control modules of contact-free control and regulating systems comprising an insulating carrier plate having one portion of one surface adjacent the control inputs provided with a plurality of anti-interference filters. The number of filters is the same as the number of control inputs. The other portion of the one surface of the plate is provided with the same number of threshold value stages connected to the filters. The other surface of the carrier plate has a metal layer thereon which is electrically interrupted in accordance with the boundary between the first and second portions of the one surface thereof. The portion of the layer corresponding to the first portion is connected to ground and the portion of the layer corresponding to the second portion is connected to a reference potential.
