Patent ID: 8013264

Claim:
A seating detection switch capable of detecting whether or not a passenger is seated in a seat comprising: a film-form substrate; a first conductor fixed to one of the surfaces of the film-form substrate, including a first terminal at one end and a plurality of first electrodes at the other end; a second conductor fixed to said one of the surface of the film-form substrate, including a second terminal at one end and one or a plurality of second electrodes at the other end; a film-form member disposed on said one of the surfaces of the film-form substrate, said film-form member being spaced from the film-form substrate; a plurality of conductors fixed to the surface of the film-form member facing the film-form substrate; and a third conductor fixed to said one of the surfaces of the film-form substrate, including a plurality of third electrodes corresponding to the first electrodes at one end and one or a plurality of fourth electrodes corresponding to the second electrodes at the other end, wherein the first and third electrodes and the corresponding plurality of conductors form a first switch, the second and fourth electrodes and the corresponding one or plurality of conductors form a second switch, and the first and second switches form an AND circuit, wherein the first conductor is insulated from the second conductor, wherein the third conductor is insulated from the first conductor and the second conductor, and wherein by the turning on of the first switch and the turning on of the second switch, the first electrode and the second electrode enter in a mutually conductive condition.
