ABSTRACT:
A bi-stable magnetic switch assembly is provided that comprises a stator and a rotor, which is configured for rotation with respect to the stator between a first latched position and a second latched position. The stator and the rotor cooperate to form a first magnetic path and a magnetic path having a shared portion. A spring, which is coupled to the rotor, biases the rotor toward the first and second latched positions when the rotor is in the second and first latched positions, respectively. At least one magnet is fixedly coupled to either the stator or the rotor. The magnet is included within the first magnetic path and configured to produce a magnetic latching force that biases the rotor toward first latched position when the rotor is closer to the first latched position than to the second latched position, and toward the second latched position when the rotor is closer to the second latched position than to the first latched position. At least one coil is fixedly coupled to either the stator or the rotor and, when energized, alters the flux in the second magnetic path to reduce the magnetic latching force.
