Method of making electrical contact having surface coating layer with irregular surface

摘要

In an electrical contact having a contacting portion to be brought into contact with and electrically connected with a terminal member, the contact comprises a metallic body having a body surface and a metallic plated layer formed on the body surface of at least the contacting portion. The metallic plated layer has hard conductive particles dispersed in the layer in order to enable to remove contamination from a surface of the terminal member when the contacting surface is brought into contact with the terminal member. The surface layer has an irregular surface due to presence of the hard conductive particles dispersed therein. When the contacting portion is brought into contact with the terminal member, the contamination is removed by irregular surface.
