Summary:A foil-type switching element comprises a first carrier foil and a second carrier foil arranged at a certain distance from each other by means of a spacer, said spacer comprising at least one recess defining an active area of the switching element. At least two electrodes are arranged in the active area of the switching element between said first and second carrier foils in such a way that, in response to a pressure acting on the active area of the switching element, the first and second carrier foils are pressed together against the reaction force of the elastic carrier foils and an electrical contact is established between the at least two electrodes. According to the invention at least one of said first and second carrier foils comprises a multi-layered configuration with an inner supporting foil and an outer elastic activation layer for introducing a force acting on the switching element into a central region of said active area of said switching element.
