ABSTRACT:
This electromagnetic relay includes: a base assembly; an electromagnetic block assembly, mounted to the base, including an iron core and an electromagnetic coil wound around the core; a movable block assembly, which is selectively attracted by the electromagnetic block assembly according to energization of the electromagnetic coil thereof, and is movable along a direction perpendicular to the axial line of the iron core; a contact mechanism including a movable contact support member actuated by the movement of the movable block assembly, a movable contact mounted to the movable contact support member near one extremity thereof, a fixed terminal member supporting the movable contact support member from the base assembly near another extremity thereof, a fixed contact support member mounted to the base assembly opposing the movable contact support member, and a fixed contact mounted to the fixed contact support member opposing the movable contact; a means for guiding the movable block assembly along the aforesaid direction perpendicular to the axial line of the iron core; a projection formed on a surface of the movable block assembly facing the base assembly; and a guide projection wall, extending from the base assembly, along a surface formed on which the projection slides; the movable block assembly being engaged to the movable contact support member so as to be substantially fixed thereto with regard to mutual movement along the axial direction of the movable contact support member. Thereby, wobbling of the movable block assembly is prevented.
