Abstract
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, which comprises one opening () defining an active area. An elongate resistive layer () is provided on the second carrier foil within the active area while elongateshunt means () are arranged on the first miler foil within the active area and facing the resistive layer (). The form of the opening () in the spacer is such that the active area generally tapers in the longitudinal direction of the elongate resistive layer (), so that when pressure is applied on the switching element, the shunt means () shunt a portion of the resistive layer () thatprogressively increases with pressure, from the broad end of the spacer opening () towards its narrow end.
