Abstract
The present invention concerns a control device for an electrical circuit integrated on a substrate made of polymeric material, incorporating carbonaceous conductive structures which define at least one track having improved electrical conductivity properties with respect to the substrate, which control device includes an operating area adapted to be acted on by a user and having a pressure-deformable structure adapted to disturb the electrical properties of the track by a piezo-resistive effect, wherein the conductive track includes at least one linear segment which has a winding progression at the operating area.
