Abstract: This electric contact device is a variant of those described in Anizan et al., French Pat. No. 2,385,208.The composite unit formed by the insulating coating and the conducting material form a single insulator-conductor unit. The electrical duct penetrates the insulation to reach the conductor. The composite unit is made of enamelled metal, a metal on which insulation is deposited by "shoopage" (a process apparently involving the deposit of a vaporized metal) or of a cermet (ceramic alloy) from whose surface the metallic phase has been eliminated. The duct may be cylindrical, a groove, or grooves crossing at a right angle.Usable for many types of electric contact.
