Abstract
An electromagnetic contactor has a stationary core; a coil arranged around the stationary core; a movable holder movable toward the stationary core; a movable core coupled to one end of the movable holder for being attracted to the stationary core by the excitation of the coil; and a nonmagnetic structural component arranged on the movable core facing the stationary core. The nonmagnetic structural component is a flat plate structural component with high flexural rigidity, overlaid on the surface of the movable core to face the stationary core. The nonmagnetic structural component and the movable core are held between a cushioning spring and a coupling pin. The cushioning spring is contained in the movable holder and buts the back face of the movable core not facing the stationary core. The coupling pin crosses the nonmagnetic structural component with both ends engaged with a pair of holder legs.
