摘要： A relay comprises a movable body placed in a cavity which is formed on a substrate and surrounded by a spacer layer and sealed by a cover layer. The movable body comprises a first magnet which is permanently magnetized and has at least a first end. A nearby switching electromagnet, when energized, produces a switching magnetic field which is primarily perpendicular to the magnetization direction of the first magnet and exerts a magnetic torque on the first magnet to force the first magnet and said movable body to rotate and close an electrical conduction path at the first end. Changing the direction of the electrical current in the switching electromagnet changes the direction of the switching magnetic field and thus the direction of the magnetic torque on the first magnet, and causes the first magnet and said movable body to rotate in an opposite direction and opens the electrical conduction path at the first end. The first magnet can comprise multiple magnetic layers to form relatively closed magnetic circuits with other magnetic components. Latching and non-latching types of relays can be formed by appropriately using soft and permanent magnets as various components.
