    摘要： A micro-machined magnetic latching switch is described. A moveable micro-machined cantilever has a magnetic material and a longitudinal axis. The cantilever has a conducting layer. A permanent magnet produces a first magnetic field, which induces a magnetization in the magnetic material. The magnetization is characterized by a magnetization vector pointing in a direction along the longitudinal axis of the cantilever. The first magnetic field is approximately perpendicular to longitudinal axis. A three-dimensional solenoid coil produces a second magnetic field to switch the cantilever between a first stable state and a second stable state. The temporary current is input to the three-dimensional solenoid coil, producing the second magnetic field such that a component of the second magnetic field parallel to the longitudinal axis changes direction of the magnetization vector. The cantilever is thereby caused to switch between the first stable state and the second stable state.

    摘要： A polarized electromagnetic relay of the conductor plate type in which a single permanent magnet is disposed between body portions of an E-shaped core yoke and a U-shaped yoke. A U-shaped armature is resiliently supported coaxially of its legs from the body portion of the E-shaped core yoke for swinging movement between the yokes. The center leg of the E-shaped core yoke is longer than the outer legs and in response to a reversal of direction of flux in the armature, the armature moves between first and second stable positions in which it bears against the legs of the Ushaped yoke and the free end of the center, and the free ends of the outer legs, respectively, of the E-shaped core yoke.
