An electromagnetic relay includes a support member, a first fixed terminal, a second fixed terminal, a movable contact piece, a movable member. The support member is made of an insulating material. The first fixed terminal includes a first fixed contact and is supported by the support member. The second fixed terminal includes the second fixed contact and is supported by the support member. The movable contact piece includes a first movable contact and a second movable contact. The movable member is connected to the movable contact piece and includes a first overlapping portion made of an insulating material. The first overlapping portion is disposed between the first fixed terminal and the second fixed terminal. The first overlapping portion overlaps with the support member when viewed from a longitudinal direction of the movable contact piece in an open state where the first movable contact is separated from the first fixed contact.

A relay includes a fixed terminal, a movable contact piece, a holder, a drive shaft, a contact case, a magnetic field generation member, and an inner member. The drive shaft is connected to the holder on a side close to the first end of the drive shaft. The magnetic field generation member is arranged around the contact case and is configured to generate a magnetic field in which an arc generated between the fixed contact and the movable contact extends in a lateral direction of the movable contact piece. The inner member includes a rotation preventing portion for restricting rotation of the holder around the drive shaft. The rotation preventing portion is arranged so as to contact the holder at a position closer to a second end of the drive shaft than the movable contact piece and closer to the drive shaft than the movable contact.

An electromagnetic device includes a fixed iron core through which a first magnetic flux flows, a movable iron core that reciprocates to separate from the fixed iron core by a predetermined gap when a current applied to a coil, which generates the first magnetic flux, is stopped and move to the fixed iron core by an attractive force when the current is applied to the coil. The electromagnetic device also includes a permanent magnet that generates a second magnetic flux. The opposed surface of the fixed iron core and the opposed surface of the movable iron core may be opposed in a reciprocating direction of the movable iron core. The permanent magnet may be attached to the fixed iron core such that a magnetized surface of the permanent magnet is opposed and exposed to the opposed surface of the movable iron core.

An electrical contactor module includes a pair of contactor assemblies each having an input contact, an output contact spaced apart from the input contact, and a linear solenoid disposed proximate the input and output contacts. Each linear solenoid has a housing, a plunger disposed within the housing so as to permit axial displacement of the plunger between an open position in which an end of the plunger is spaced apart from the input and output contacts and a closed position in which the end mechanically contacts and electrically couples the input and output contacts, a spring for biasing the plunger in the open position, and a coil within the housing for urging the plunger from the open position to the closed position along a linear direction. The contactor assemblies are fastened and arranged within an enclosure, with the linear directions for the contactor assemblies pointing in generally opposite directions.
