摘要： There is provided a contact switching device which has high productivity and in which operation characteristics hardly vary. The contact switching device includes an electromagnetic unit, a holder, a movable shaft, a movable yoke, a movable contact piece having movable contacts at both ends, fixed contacts, and a fixed yoke. At the time of excitation of the electromagnetic unit, the movable shaft moves to the holder side along a direction of an axis center. A magnetic circuit is formed of the fixed yoke and the movable yoke due to a magnetic field generated by a current that flows into the movable contact piece as a result of the movable contacts coming into contact with the fixed contacts. The movable yoke is then attracted to the fixed yoke.

摘要： The invention provides a sealed contact device capable of extinguishing an arc which extends in an arbitrary direction. The sealed contact device includes a housing; a fixed contact and a movable contact disposed in the housing in such a manner as to face each other; and permanent magnets which are disposed with the fixed contact and the movable contact interposed therebetween and which attracts an arc between the fixed contact and the movable contact using a magnetic force. An arc shielding member is disposed at a position to which the arc is attracted by current flowing between the fixed contact and the movable contact and by the magnetic force between the permanent magnets, in the housing.

摘要： An electromagnetic relay includes a fixed terminal, a movable contact piece, a first contact, and a second contact. The fixed terminal includes a first surface. The movable contact piece includes a second surface disposed to face the first surface. The first contact is embedded in one of the fixed terminal or the movable contact piece to be flush with one of the first surface or the second surface. The second contact is disposed on the other of the fixed terminal or the movable contact piece to face the first contact. The second contact protrudes from the other of the first surface or the second surface toward the first contact and include a contact surface smaller than the first contact when viewed from a direction facing the first contact.

摘要： A relay includes a movable contact piece having a first movable contact and a second movable contact, a first fixed terminal having a first fixed contact, a second fixed terminal having a second fixed contact, a drive device configured to move the movable contact piece, and the wall portion disposed inside the first fixed contact and the second fixed contact in a longitudinal direction. At least a part of the wall portion is disposed at a position beyond the first fixed contact and the second fixed contact toward the movable contact piece in a moving direction of the movable contact piece. The movable contact piece has a shape so as to avoid the wall portion in a contact state where the first movable contact is in contact with the first fixed contact and the second movable contact is in contact with the second fixed contact.

摘要： A relay includes a first fixed contact, a second fixed contact, a movable contact piece having first and second movable contacts, a contact piece holding unit configured to hold the movable contact piece, and first to fourth magnets. The first magnet and the second magnet are disposed so that same poles thereof face each other. The movable contact piece is disposed between the first magnet and the second magnet in a width direction of the movable contact piece. The third magnet is disposed so as to increase a magnetic flux in a longitudinal direction of the movable contact piece at a position between the first fixed contact and the first movable contact. The fourth magnet is disposed so as to increase a magnetic flux in the longitudinal direction of the movable contact piece at a position between the second fixed contact and the second movable contact.
