ABSTRACT:
In an electromagnetic contactor, a coil spool (5) in which a coil (5A) is wound and a movable iron core (4) is movably mounted, a cover (20) in which a crossbar (10) having a movable contact (15) is slidably mounted, and a mechanical link (6) which makes a mechanical linkage of the movable iron core (4) with the crossbar (10) are arranged such that the positioning between the coil spool (5) and the cover (20) is defined by making contact of an engaging member (60) of the cover (20) with the coil spool (5); and the coil spool (5) is relatively pushed to the engaging member (60) from a coil terminal (25) fixed in the cover (20) by means of an elastic force of a contact terminal (35) which is provided in the coil spool (5) and makes electrical connection between the coil (5A) and the coil terminal (25).
