Abstract
Provided is a pair of arc discharge suppressive terminals electrically communicable with each other by engagement of the terminal pair. At least one of the terminal pair has a final contact site which is in contact with the counterpart terminal at a final stage of disengagement of the terminal pair. At least the final contact site is covered with an arc discharge suppressive layer containing a first metal having a melting point of 1,550° C. or higher. It is preferable that the terminal pair contact with each other at a portion corresponding to a main contact site other than the arc discharge suppressive layer in a completely engaged state where the one of the terminal pair and the counterpart terminal are tightly engaged with each other. Preferably, the main contact site has a surface made of a material having a higher conductivity than the arc discharge suppressive layer. This arrangement effectively suppresses occurrence of arc discharge at a time of disengagement of the terminal pair.
