Abstract
A contact mechanism where a shape of at least one of a fixed contactor including a pair of fixed contact portions and a movable contactor including a pair of movable contact portions capable of contacting with and separating from the pair of fixed contact portions is set to a shape that generates a Lorentz force resisting electromagnetic repulsion in a contactor opening direction generated between the fixed contact portions and the movable contact portions when a current is applied, has the fixed contactor and the movable contactor being inserted in a current path. Magnetic bodies are disposed on at least one of the fixed contactor and the movable contactor for suppressing a force driving arcs, which are generated between the pair of fixed contact portions and the pair of movable contact portions, to the fixed contactor on the opposite side.
