Abstract
A contact device includes a contact mechanism including a pair of fixed contacts disposed to maintain a predetermined distance and a movable contact disposed to be capable of contacting to and separating from the pair of fixed contacts. The movable contact has a conductive plate portion extending in a direction crossing a moving direction of the movable contact in a contact housing case. Each of the pair of fixed contacts includes an inner side conductor plate portion having one end and the other end portion extending toward the outside of the contact housing case in parallel to the conductive plate portion, and an outer side conductor plate portion connected to the other end portion of the inner side conductor plate portion and extending in a direction separating from the movable contact, to form an L-shaped conductor portion to generate a Lorentz force opposing an electromagnetic repulsion force.
