Abstract
A foil style switching element includes a first carrier foil and a second carrier foil arranged at a certain distance from one another and a plurality of contact arrangement arranged between the first and the second carrier foils. The contact arrangements are arranged on the first and second carrier foils so that an electric contact between the contact arrangements is generated when the first and the second carrier foil are pressed together. A foil style luminescent screen unit applied on a side of the first carrier foil facing away from the second carrier foil, the luminescent screen unit includes a first electrode layer, a dielectric layer, a luminescent matter layer and a second electrode layer. The first electrode layer of the foil style luminescent screen unit is applied directly on the first carrier foil which faces away from the second carrier foil.
