<p>The invention is about the displacement response sensor by push down contact , because the contact department (11) is consist of the materials that contains electric conduction and the plastics that the elasticity is good or the rubber of softness such as gum or silicon, when push down contact is made to the contact department, the Semi Conductive Metrix (14) is reduced, and the density of the electric conduction (15) of the Semi Conductive Metrix (14) becomes large to sense the push down contact, and because it is made of the soft materials, it can be made and installed as various forms. It is easy to make and install, so it can be installed to the automatic revolving door (D), automatic sliding door (D), the bumper of vehicle, on the front and back of the streetcar, measuring machine of pressure or weight, and on the system or pipe that use gas, it can be used to measure the pressure of air or liquid and so on.</p> |
