发明名称 Polarized electromagnetic relay
摘要 A polarized electromagnetic relay has a movable block which includes two U-shaped magnetic plates, each of which has first and second ends. The plates are fixed on individually associated and opposite poles of a permanent magnet to oppose each other. A core has one end placed between the two magnetic plates. A yoke is magnetically connected to the core, the yoke having a fork on one end thereof. The fork is placed outside each of the two magnetic plates. A spool with a coil mounted thereon has a center hole through which the core is inserted. The movable block is supported in a manner which enables it to move in a direction which is parallel to the magnetic axis of the permanent magnet.
