Abstract
A switching device comprises a flexible film of insulative material on which is printed a pictorial diagram or the like illustrating a plurality of controlled devices. A plurality of first conductive elements is arranged on a plane in contact with the illustration film and a plurality of second conductive elements is arranged on a second plane spaced from the first plane. In response to a pressure manually applied to the illustration film at a point corresponding to a desired controlled device, the first and second elements of the corresponding pair are brought into electrical contact to complete a circuit through a pair of terminals. Preferably, between each pair of corresponding first and second conductive elements is disposed an elastic element having resistance which varies from a non-conductive value to a conductive value in response to a pressure applied thereto.
