Abstract

756,393. Switch contacts. JOHNSON, MATTHEY & CO., Ltd. Feb. 21, 1955 [Feb. 23, 1954], No. 5331/54. Class 38(5) [Also in Group XXII] A rivet-type electrical contact 10 formed by extrusion (see Group XXII) has a hollow shank which may be bifurcated at its end to facilitate its attachment to a support. The bifurcations are bent outwardly upon assembly and lead wires are soldered thereto. The contact face may be convex, concave, flat or dish-shaped. The contact may be made of copper, silver, gold, platinum or palladium or it may be bi-metallic consisting of a contact face of silver, gold or other precious metal on a base of copper. A metallic, bi-metallic or tri-metallic sintered powder compact may be used for forming the contact.
