Claim:
1. A contact structure, wherein a live contact portion and an auxiliary contact portion of an auxiliary contact body in a first contact front on a movement path of a second contact at positions shifted in front and rear directions while being distanced by a width that allows the live contact portion and the auxiliary contact portion to simultaneously contact the second contact, the second contact contacting and separating from the first contact along with advancing/withdrawing movements in front and rear directions, if moved forward, the second contact contacts the auxiliary contact portion, and then contacts the live contact portion to establish a live connection with the first contact, and if moved backward, the second contact separates from the live contact portion, and then separates from the auxiliary contact portion, the auxiliary contact body is always in an electrical connection with the first contact at a base end connected portion before the live contact portion, and the auxiliary contact body is formed from a high resistance resistor having a resistance value between the auxiliary contact portion and the base end connected portion such that the resistance value suppresses arcing between the second contact and the auxiliary contact portion.
