An electromagnetic relay includes an armature, and a movable body configured to move in association with a swing of the armature. The armature includes a support portion opposed to a leg portion of an iron core, a magnetic pole opposed to another leg portion of the iron core, and an arm portion extending to connect the support portion and the magnetic pole. A movable body is attached to the arm portion and provided with a pressure projection for moving movable contacts. The pressure projection is located on a segment connecting the center of gravity of the support portion and the center of gravity of the magnetic pole.

A second yoke is disposed at a distance from a first yoke in a predetermined first direction. The movable unit is disposed between the first yoke and the second yoke. The movable unit is rotated by magnetic force from the first yoke and the second yoke to switch between a contact state and a non-contact state of a first contact and a second contact. The first conductive member has an extending portion extending in a second direction vertical to the first direction. The extending portion and a second conductive member are disposed at positions not overlapping with the relay body as viewed in a third direction vertical to the first direction and the second direction.

invention relates to a relay, having an electromagnetic drive with a field coil arranged around an iron core which defines a plane, and a yoke. The electromagnetic drive works together with a movable armature which can switch a movable electrical contact via an actuating arrangement. The relay is accommodated in a housing, wherein an intermediate base and/or partition is included between the electromagnetic drive and the contact. The electromagnetic drive is arranged on one side of the partition, and the movable electrical contact is arranged on the other side of the partition. The partition has an opening through which the mechanical actuation of the contact is carried out. Because the armature is pivotable about an axis of rotation perpendicular to the plane of the iron core, the relay can have a lower constructed height than a conventional relay.
