ABSTRACT:
An electromagnet relay is disclosed. The relay comprises at least one electromagnet relay-contact assembly and a housing for containing the electromagnet relay-contact assembly. The electromagnet relay-contact assembly comprises at least one contact block including at least one of a normally-open contact and a normally-closed contact, an electromagnet device including a coil wound on an iron core and a relay armature for actuating the contacts by energization of the coil, and lead-out terminals for the contacts and the coil. The bottom wall of the housing is formed with a downwardly-protruded expansion, and a recess is formed in the inner surface of the bottom wall corresponding to the expansion. The electromagnet relay-contact assembly is contained in the inner space of the housing in such a manner that the lower half of the coil is substantially placed within the recess. The lead-out terminals are extended downwardly through longitudinal flat portions connected with the expansion of the bottom wall.
