Abstract: An electromagnetic relay, comprising: a electromagnet consisting of an iron core and a solenoid wound thereon; a yoke extending in parallel with the electromagnet and attached to one end of the iron core; an armature pivotally attached to a part of the yoke adjacent to another end of the iron core at its base end; a fixed contact unit provided adjacent to the electromagnet; an pivotally supported moveable contact carrier; an extension arm extending from the armature and having a free end adapted to abut an actuation point of the moveable contact carrier located between its pivoted point and a moveable contact piece carried thereby; the moveable contact piece being adapted to cooperate with a fixed contact member provided in the fixed contact unit.

Abstract: An electromagnet device is assembled to, e.g., an electromagnetic relay. This device comprises a movable assembly which is swingably supported and a core in which a coil is wound around a part thereof. The movable assembly has two magnetic plates arranged so as to face each other with a distance and one permanent magnet arranged between those magnetic plates. Each magnetic plate has operating portions at both end portions thereof in which magnetic poles appear due to the permanent magnet. The core has two end portions which are arranged so as to respectively face the operating portions of the magnetic plates. At least one of the operating portions which faces at least one of the end portions of the core is formed at the edge surface of the magnetic plate.
