1. A low power consumption electromagnetic actuator comprising
a) a stator body comprising at least one set of two protruding legs and a connecting segment connecting the at least one set of two protruding legs and having a vertical and a horizontal axis of symmetry,
b) at least two permanent magnets attached to the stator body,
c) a winding coil around the connecting segment,
d) at least one flexure positioned between at least two pole faces,
wherein the at least one flexure is formed of a material having a stiffness and a strain range sufficient for permitting rotor rotation or mover movement, formed of a material with a Young's modulus less than the Young's modulus of aluminum, and
e) a rotor or mover comprising at least two opposing regions, the rotor contacting the at least one flexure, and
a contact spring connected to the rotor or the mover for transfer to and storage of energy in the contact spring,
wherein each permanent magnet forms a pole face on the stator body about the site of its attachment and on one end of the flexure and not within a primary magnetic flux path.
