The invention discloses a distributor contact which is characterized in that the distributor contact is composed of three different metal layers, namely, a tungsten metal layer, a copper metal layer and an iron metal layer; the surface of the tungsten metal layer is provided with two slots which are distributed in a 'cross' shape, and the 'cross' slots are uniformly distributed on the surface of the tungsten metal layer; the metal layers are connected together through welding; and the distributor contact is coated with a layer of isolated conductive heat insulation coating. According to the invention, the 'cross' slots are arranged in the surface of the contact, and the contact has a simple structure and is easy to operate. Among metals, tungsten has the highest melting point, has good heat conduction, electrical conduction and electron emission performances and is not easy to soften, copper has excellent ductility and corrosion resistance, makes welding firmer and further enhances the conductive ability, and iron has high melting point and high thermal conductivity and facilitates heat radiation. The surface of the contact is coated with the isolated conductive heat insulation coating, which can achieve good isolation and heat insulation effects and improve the utilization rate.
