    摘要: A switch is configured that: in the closed-circuit state, at least part of its movable contact arm enters into a oblong generally hexahedral space defined by its elongated stationary conductor in its closed circuit position. Both contacting and breaking of the moving contact and the fixed contact occur in the space. Overall electromagnetic forces generated by the current flowing through the stationary conductor, movable contact arm and the arc induced at the time of breaking effectively act to extend the arc toward a terminal section of the stationary conductor and to increase the arc resistance at the time just after the breaking of both the contacts.
