Abstract: A rubber and metal composite electric contact and a preparation process therefor. The rubber and metal composite electric contact is a circular layered complex which is formed by tightly combining a metal sheet layer having a plurality of through holes and a rubber layer by means of thermal vulcanization molding and which has a thickness of 0.1 to 5 mm and a diameter of 1 to 15 mm. There is no isolation layer between the rubber layer and the metal layer of the electric contact, so no rubber overflows the outer surface of the metal layer. In the rubber and metal composite electric contact, the rubber and metal are combined firmly and the overall strength of the electric contact is adjustable; the electric contact also has good dust resistance; and the electric contact thus has stable and reliable electrical conductivity.
