Abstract

A device is proposed for detection of trapping in a power-operated closing element (4) with a switching element (24), which is arranged along a first closing edge, and at least two force transmitters (16) extending longitudinally, which flank the closing element (4) laterally in the closed position and transmit a trapping force to the switching element (24) in the case of trapping. The switching element (24) is designed as a foil-type element with two carrier foils (36), which are arranged above each other a specific distance apart. At least two contact elements to (40) are arranged on the carrier foils (36) in such a way that two longitudinal active areas (26) separated from each other by a longitudinal spacer (42) are formed, each active area (26) being arranged in the range of action of a force transmitter (16).
