  • Patent number: 4847586
    Abstract: There provided is a pressure detector accurate in operation and high in reproducibility to have a resistance circuit substrate provided with at least one pair of electrodes and forming a resistance circuit between the electrodes through printing or other means, a block contact maker formed of a conductive elastic material to a shape ready for deforming, which is characterized in that the block contact maker is kept in contact with the resistance circuit substrate at all times, the block contact maker is deformed according as the state shifts from non-pressurized to pressurized to change a contact area gradually with the resistance circuit substrate, thus forming a variable resistance circuit parallel electrically with the resistance circuit substrate.
