An electromagnetic relay includes a movable terminal including a movable contact, a fixed terminal including a fixed contact that faces the movable contact, first irons disposed on one of the fixed terminal and the movable terminal, and a second iron disposed on another one of the fixed terminal and the movable terminal such that the second iron at least partially overlaps both of the first irons.

A displaceable portion of a moving contactor is connected to, and electrically conductive with, a pair of moving contacts. An armature actuates the moving contactor. The armature has an adhering portion to be adhered onto an electromagnet. A space inside an opening that exposes a part (an exposed part) of the displaceable portion crosses a predetermined plane. The predetermined plane intersects at right angles with an arrangement direction (a first direction) in which the pair of moving contacts is arranged side by side. The predetermined plane passes through a center between both ends in the arrangement direction of the adhering portion.

A magnetic system of an electromagnetic relay comprises a coil, an iron core, a yoke, and an armature. The iron core extends through the coil and has a first end and a second end opposite to the first end. A second part of the yoke is connected to the first end of the iron core and a first part of the yoke extends in a length direction of the iron core and is separated from the coil. The armature is disposed at the second end of the iron core and has a main body and a bending portion bent from the main body by a predetermined angle. The main body faces an end surface of the second end of the iron core. The bending portion is disposed at an inner side of an end portion of the first part of the yoke and faces the iron core.

A high-insulation small-sized hinged electromagnetic relay, includes a bobbin, coil terminals, an iron core and a fixed contact block. The bobbin has a cylindrical portion for winding a coil, and the iron core includes a mandrel and a magnetic pole portion arranged on the upper end of the mandrel; the mandrel of the iron core is fitted into the central hole of the cylindrical portion of the bobbin, the coil terminals is assembled on the lower flange of the bobbin and positioned on one side in the width direction of the bobbin, and the fixed contact block is interposed in the upper flange and the lower flange of the bobbin and positioned on the other side in the width direction of the bobbin; the cylindrical portion is offset.

A contact mechanism includes: a movable touch piece that includes a caulking portion, a pair of arms forked from the caulking portion and respectively having free ends, first and second movable contacts provided at the respective free ends of the pair of arms, and a coupler configured to couple the free ends of the pair of arms; and first and second fixed contacts disposed respectively facing the first and second movable contacts contactably to or separably from the first and second movable contacts.

An electromagnetic relay including: an electromagnet; a movable spring having a movable contact; a first terminal to which one end of the movable spring is connected; a second terminal having a fixed contact opposite to the movable contact; an actuator that rotates by excitation of the electromagnet, rotates the movable spring, and causes the movable contact to come in contact with the fixed contact or to separate from the fixed contact; a nonmagnetic card to be attached to the actuator; a plurality of magnetic members that sandwich the movable contact and the fixed contact, and apply a magnetic flux to the movable contact and the fixed contact to extend an arc; and a permanent magnet attached between the magnetic members.
