Abstract

591,183. Switch contacts. POINTOUT, R. April 30, 1945, No. 10902. Convention date, Jan. 8, 1944. [Class 38 (v)] [Also in Group XXII] A contact comprises a concavo-convex insert 3, Fig. 1, flattened by pressing it into a body 2 recessed to receive it, and upsetting the edges of the recess over the edges 3a, of the insert, the edges 3a being rendered oblique by the flattening operation. The insert 3 may be of copper, silver or tungsten, and the body 2 may be the head of a bolt of cheaper metal, e.g., steel.
