Abstract
An impact sensor system with at least one foil-type switching element having a plurality of active areas including at least a first a second carrier foil arranged at a certain distance by at least one first spacer.The spacer has a plurality of recesses defining at least a first part of the active areas. In each active area, at least two electrode structures are arranged between the first and second carrier foils in such way that in response to a force acting on the active area, the first and second carrier foils are pressed together against the reaction force of the carrier foils and that, above a predetermined activation threshold force, an electrical contact is established between the electrode structures. The foil-type switching element is configured such that the activation threshold forces of a first group of said the active areas and a second group of active areas is different.
