Patent ID: 7372350

Claim:
An electromagnetic relay comprising: an electro-magnet block having an iron core around which a coil is wound, a yoke being attached to one end of said iron core, an armature that is placed in a position being opposite to another end of said iron core and is attracted by the energized iron core, and a hinge spring that supports said armature in such a manner that said armature is capable of rocking or swinging; a card block which comprises a pair of holding frames each being electrically separated and being mechanically connected by an insulating material, a pair of movable contactor springs being joined to said holding frames, a pair of movable contactors being joined to each of said movable contactor springs and each having at least one movable contact in a fixed manner, and a pair of release springs to return said movable contactors from an operating state to a released state, said electro-magnet block being superposed over said card block with said armature engaging said card block at a pressure point; and a base block to support at least two fixed terminals each having a fixed contact and two coil terminals using an insulating material for a base, said card block being superposed over said base block; and wherein the at least two movable contacts of said card block are placed approximately in one plane and the at least two fixed contacts each are placed in positions facing a corresponding one of the at least two movable contacts on said base block, and the at least two movable contacts and the at least two fixed contacts are simultaneously opened and closed in synchronization with the rock or swing of said armature.
