Abstract
A contact device includes a contact point block, a drive unit, and permanent magnets. The contact point block includes fixed terminals having fixed contact points and a movable contactor having movable contact points arranged side by side on one surface of the movable contactor. The movable contact points are configured to come into contact and out of contact with the fixed contact points. The drive unit drives the movable contactor such that the movable contact points come into contact and out of contact with the fixed contact points. The permanent magnets are arranged in a mutually opposing relationship across the contact point block along a direction orthogonal to an arrangement direction of the movable contact points and to a direction in which the movable contact points come into contact and out of contact with the fixed contact points. The permanent magnets are provided with mutually-opposing surfaces having the same polarity.
