Magnetic armature, contactor with magnetic armature and method of switching contactor

摘要

The present invention relates to a magnetic armature for a contactor, a contactor and a method for switching such contactor. The magnetic armature may reduce the risk of the contacts of the contactor being adhered thereto, and comprises a first spring element having a first stiffness and a second spring element having a second stiffness. Further, the present invention deforms the first spring element when switching from the stop point to the intermediate point. And the second spring element is deformed when changing from the intermediate point to the final point.
