摘要： An electromagnetic relay is basically constructed by an insulation base and an armature block. Herein, the insulation base is constructed by a fixed-side terminal set including fixed contacts, a coil block in which a coil is wound about a middle portion of a U-shape iron core, and a permanent magnet, all of which are integrally held together by a fixed-side insulator. The armature block is constructed by a moving-side terminal set including moving contacts and an armature, all of which are integrally held by a moving-side insulator. The armature block is mounted on the insulation base in such a way that the moving contacts are placed opposite to the fixed contacts respectively, and it is supported by a support point to pivotally move on the permanent magnet under an effect of electromagnetic force. Specifically, the fixed-side insulator is made by molding using resin material to integrally hold the fixed-side terminal set, coil block and permanent magnet together at prescribed positions, so it is possible to improve an accuracy in positioning of them. In addition, the fixed-side insulator is formed in a prescribed shape having a contact fixing portion that partly extends to provide engagement portions by which the permanent magnet and U-shape iron core are tightly fixed together under a contact condition where the permanent magnet is placed in tight contact with the side-end portions of the U-shape iron core.
