PROBLEM TO BE SOLVED: To suppress effectively the occurrence of arc discharges, in applications where a voltage between terminals, immediately after disconnecting, is 36 V to 60 V, and a current between the terminals during contact becomes 6 A to 30 A. SOLUTION: The terminal-carrying current by contact with the other terminal is formed of a metal member, of which a base material of the electrically contacting part is composed as a main component of at least one metal selected from among a group, consisting of Cu, Ni and Sn.
