Device for detection of trapping in a power-operated closing element

A device for detection of trapping in a power-operated closing element comprising:

• foil-type switching element, which is arranged along a first closing edge, and least two force transmitters extending longitudinally, said force transmitters flanking the closing element laterally, when said closing element is in a closed position, and transmitting a trapping force to said switching element in the case of trapping, wherein said foil-type switching element comprises a first and second carrier foil, a longitudinal spacer and at least two contact elements, said first and second carrier foils being arranged above each other at a specific distance, and said at least two contact elements being arranged on said first and second carrier foils in such a way that two longitudinal active areas are formed which are separated from each other by said longitudinal spacer, each active area being arranged respectively in the range of action of one of said force transmitters;
• wherein one of said contact elements is arranged on each of said first and second carrier foils in such a way that the two contact elements are opposite each other and are brought into contact when said first and second carrier foils are pressed together.
