FOIL-TYPE SWITCHING ELEMENT

摘要

A foil-type switching element (10) comprises a first carrier foil (12) having a first electrode arrangement applied thereon and a second carrier foil (14) having a second elec-trode arrangement applied thereon, said first and second carrier foils being arranged at a certain distance by means of a spacer (16) in such a way that said first and second electrodes face each other in an active area of said switching element. At least said second electrode arrangement comprises a resistive layer which faces said first electrode arrangement. In response to a pressure acting on said switching element said first and second electrode arrangements are pressed together, the shape and/or the size of a mechanical contact (20) surface between said first and second electrode arrangements being given by a mechanical response function depending on the amount of pressure applied. According to the invention, said resistive layer has a shape such that an electrical response function of said sensor is decoupled from said mechanical response function.
