Abstract
A sheet-like pressure sensitive switch is disclosed. A spacer 2 of an insulating material is interposed between a first film 1 of an insulating material which is provided with a first electrode 1a and a second film 3 of an insulating material which is provided with a second electrode 3a. The spacer 2 has a number of openings 2a, through which the first electrode 1a and the second electrode 3a oppose each other with an air gap therebetween. A first lead wire 4a and a second lead wire 4b are connected to the first electrode 1a and the second electrode 3a, respectively. In a pressure sensitive switch according to a first embodiment, the first and the second film 1, 3 are formed of polyethylene naphthalate films. In a pressure sensitive switch according to a second embodiment, the second film 3 is formed of polyethylene terephthalate film while the first film 1 is formed of polyethylene naphthalate film.
