Abstract
The utility model relates to a welding silver layer contact for a relay contact bridge. The contact comprises a pure-copper arc matrix (1) and a contact composite layer (3), wherein the pure-copper arc matrix (1) is a long strip shape. One end of the pure-copper arc matrix (1) is arc-shaped. A right-angle connection board (2) is vertically arranged on one side of a middle part of the pure-copper arc matrix (1). Plugboards (4) are mounted on two sides of the pure-copper arc matrix (1) on one side of the right-angle connection board (2). The contact composite layer (3) is disposed on an upper side of the other end of the pure-copper arc matrix (1). The welding silver layer contact adopts composite forming of pure copper and pure silver materials, production cost is low, conductivity is high and contact resistance is low and stable.
