Abstract
Provided is a contact contacting structure that reliably prevents the development of arc discharge in a simple configuration regardless of the magnitude of electric energy accumulated between a pair of contacts that are connected and disconnected. An intermediate contact body disposed continuously with a first contact along a movement path of a second contact is formed from material with higher electric resistivity than the first contact in a shape such that the cross sectional area of a transverse section perpendicular to the movement path is gradually decreased in a separating direction along the movement path.
