Abstract

The invention relates to a bistable micro-electromechanical relay, in particular to a micro miniature relay with state maintaining function, which is mainly applied to systems of power supply management, instruments and meters, automatic control and wide band communication, etc. The relay comprises a packaging cover, a base pin, a movable diaphragm, micro balloons and an electromagnetic base plate; wherein, the movable diaphragm and the micro balloons are positioned in a hollow cavity formed after the packaging cover, and the electromagnetic base plate are fixedly connected, upper electrodes opposite to the lower electrodes at the left end and the right end of the upper surface of the electromagnetic base plate are respectively arranged at the two ends of the movable diaphragm, round holes are distributed along the longitudinal symmetric axis of the movable diaphragm, and are movably positioned on the corresponding micro balloons, and the microballoons are movably positioned on the round holes of a microballoon base seat on the electromagnetic base plate. The integration level of the relay is high, bistable electromagnetic driving and state locking are realized, the driving energy consumption and the working loss are reduced while the response speed and the service life of the relay are obviously improved, the response time is short, the insulating strength and the compression strength are high, and the work is stable.
