Abstract: An electromagnetic contactor with connecting spring including: a movable core contact plate section that is inserted into a through hole formed in a movable core and comes into contact with a contact support side of the through hole; and a pair of curved plate sections each joined to either end of the movable core contact plate section and housed in connecting spring tip housing sections formed in the contact support, the sides of which opposite to a contact surface of the movable core contact plate section come into contact with the connecting spring tip housing sections. In the movable core contact plate section, a depressed section is formed in a direction crossing a longitudinal direction to bulge out to an opposite side to the contact support side is formed, and contact sections that come into contact with the through hole are formed on both ends of the depressed section.

Abstract: The DC operated polarized electromagnet includes a spool around which an excitation coil is wound and that has a central opening, a plunger having first and second armatures, fitted individually, an outer yoke enclosing opposing side faces of the spool so as to attract the first armature, an inner yoke arranged on the inner side of the outer yoke so as to attract the second armature, and permanent magnets arranged between the outer yoke and the inner yoke, and reduces magnetoresistance by setting the thickness of the outer yoke thicker than the thickness of the inner yoke so that convergent magnetic flux in the plunger is diverted into the outer yoke.
