Abstract
Terminal-bolts and a fixed contact are formed with different kinds of metals, and fixed to a fixing hole formed in the fixed contact by press fitting one end of the terminal-bolts. A plurality of concavo-convex parts is provided on a surface of the fixed contact that faces the movable contact. A plurality of concavo-convex portions is provided on another surface of the fixed contact that faces an anti movable-contact side. The concavo-convex portions are arranged so that positions of concave parts of the concavo-convex portions match positions of convex parts of the concavo-convex portions provided in the opposite surface of the fixed contact. The concavo-convex parts are at least partly curved, and have the same height and project in a height direction from the fixed contact.
