    • 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.______________________________________________________
    • 箔型开关元件(10)包括其上施加有第一电极布置的第一载体箔(12)和其上施加有第二电极布置的第二载体箔(14),所述第一和第二载体箔布置 通过间隔件(16)在一定距离处,使得所述第一和第二电极在所述开关元件的有效区域中彼此面对。 至少所述第二电极装置包括面向所述第一电极装置的电阻层。 响应于作用在所述开关元件上的压力,所述第一和第二电极装置被压在一起,所述第一和第二电极装置之间的机械接触面(20)表面的形状和/或尺寸由机械响应函数取决于取决于 对施加的压力量。 根据本发明,所述电阻层具有使得所述传感器的电响应功能与所述机械响应功能分离的形状。
