Seating detection switch

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.
