Patent ID: 7504915

Claim:
An electromagnetic relay in which an electromagnetic block having an iron core around which a coil is wound; a movable block having an iron piece which is attracted to and separated from a magnetic pole portion of the electromagnetic block, the movable block being normally and reversely rotated by magnetic excitation and demagnetization of the electromagnetic block; a moving body engaging the movable block to be reciprocally moved in a linear direction according to the normal and reverse rotations; and a plurality of contact mechanisms in which switching is operated by the movement of the moving body are assembled to a base, wherein the electromagnetic block and the movable block are arranged such that a rotating shaft of the movable block is vertically located with respect to a bottom surface of the base, a fixed contact piece and a movable contact piece in the plurality of contact mechanisms are arranged such that longitudinal directions of the fixed contact piece and the movable contact piece are parallel to the bottom surface of the base, the plurality of contact mechanisms are arranged in parallel with the moving direction of the moving body in which respective pairs of the plurality of contact mechanisms are alternately arranged in upper and lower stages along the moving direction of the moving body without any straddling between any two of the contact mechanisms making up one of the pairs of the contact mechanisms arranged on the upper stage and any two of the contact mechanisms making up one of the pairs of the contact mechanism arranged on the lower stage, a terminal connected to the fixed contact piece and a terminal connected to the movable contact piece are projected downward from the bottom surface of the base, and an idle end portion of the movable contact piece is latched in the moving body.
