Patent ID: 7064650

Claim:
Foil-type switching element comprising: a first carrier foil with a first active electrode arrangement applied thereon; and a second carrier foil with a second active electrode arrangement applied thereon, said first and second carrier foils arranged at a certain distance by a spacer such that said first and second active electrode arrangements face each other in an active area of said switching element, wherein at least said second active electrode arrangement comprises a resistive layer that faces said first active electrode arrangement, wherein, in response to a pressure acting on said switching element, said first and second carrier foils are pressed together so that a mechanical contact surface is established between said first and second carrier foils, wherein a form and a size of said mechanical contact surface is given by an amount of pressure applied and so that an electrical contact surface is established between said first active electrode arrangement and said resistive layer, and wherein said resistive layer has a shape that generates a mismatch between said mechanical contact surface and said electrical contact surface.
