Electro mechanical relay uses permanent magnets set into the yoke to provide monostable or bistable operation

摘要

The electromechanical relay has an electromagnetic actuator that has a coil [2], a yoke [4] and a movable armature [5]. The unit is configured for monostable or bistable operation and uses permanent magnets. The magnets maintain the correct relay state and are located in the correct position by being set into the yoke.
