Abstract
A magnetic latching relay of a parallel type magnetic circuit, forming two parallel permanent magnetic circuits on the permanent magnetic circuit of a relay; one of the permanent magnetic circuits is used to provide adequate attraction to an armature, so that permanent magnetic attraction can achieve a balance of applied forces with the counter-force provided by a movable spring, so as to realize relay bistability or state transition more stably.
