摘要： An electromagnetic relay includes an electromagnet device, an armature and a fixed terminal. By coil current through a coil, the electromagnet device generates first magnetic flux that forces the armature and the electromagnet device together or apart in a first end in a first direction of the armature. The armature is connected with a movable contact at a second end of the first direction and forces the movable contact and a fixed contact together or apart according to coil current. The fixed terminal is electrically connected with the fixed contact, and provided around the armature so as to cross the armature as seen from a second direction perpendicular to the first direction with the armature closing the fixed and movable contacts. Electric current through the fixed terminal generates a second magnetic flux in the armature, a direction of which is opposite to that of the first magnetic flux.

摘要： An electromagnetic relay includes an exciting coil, a pair of fixed contacts, a movable spring, a magnet, and a yoke in contact with the magnet. The pair of fixed contacts is arranged along a first direction. The movable spring comes into contact with or moves away from the fixed contacts in response to the turn on or off of current to the exciting coil. The magnet prolongs the arc generated between the fixed contacts and the movable spring. The magnet is adjacent to the fixed contacts along a second direction orthogonal to the first direction, and is adjacent to the exciting coil along a third direction orthogonal to the first direction and the second direction. The yoke is adjacent to the fixed contacts along the third direction in a state where the yoke is in contact with the magnet.

摘要： 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.
