Abstract
A contact structure is provided. The contact structure suppresses arcing that can occur between contacts that establish a live connection, without increasing the size of the contact structure, and without making longer the length of the inserting/drawing stroke of a correspondingly formed contact. A live contact portion of a first contact, and an auxiliary contact portion of an auxiliary contact body configured with a high resistance resistor having a base end connected portion that establishes an electrical connection with the first contact front on a movement path of a second contact at positions that are shifted in front and rear directions while being distanced by a width that allows simultaneously contact with the second contact. If the second contact separates from the first contact, the auxiliary contact body configured with the high resistance resistor intervenes between the first contact and the second contact, and inhibits arcing.
