Abstract
The micro relay of the present invention comprises a base substrate, an armature block, and a cover. The base substratehas a storage recessfor accommodating an electromagnetic device. The storage recess is composed of a holepenetrating the base substrateand a thin storage recess lid fixed on the one surface of the base substrate to close the hole. The electromagnetic deviceis isolated from a contact mechanism by the storage recess lidto increase the reliability of the contacts. The electromagnetic deviceincludes a yoke, a coilwound around the yoke to generate a flux in response to an exciting current, and a permanent magnetsecured to the yoke to generate a flux flowing through an armatureand the yoke. Because the permanent magnetis secured to the yoke, this micro relay can reduce the thickness.
