Patent ID: 8188817

Claim:
An electromechanical relay, comprising: a substrate, wherein said substrate comprising a first set of stationary contacts and a second set of stationary contacts; a movable body attached to said substrate having a rotational axis; said movable body having a first end and a first set of movable contacts associated to said first end, and a second end and a second set of movable contacts associated to said second end; and said movable body further comprising a first magnet having a permanent magnetization moment and a set of springs; wherein said first magnet and said set of springs being affixed together by over-mold forming a unified body; a switching magnet having a coil, wherein passing a current through said coil generating a switching magnetic field which has a main component primarily perpendicular to said permanent magnetization moment in the region where said switching magnetic field goes through said first magnet, and as a result of the vector-cross product of said switching magnetic field and said permanent magnetization moment producing a torque on said first magnet and causing said movable body to rotate about said rotational axis; an over-mold housing comprising a top cover, and an enclosing side wall wherein said coil being embedded in said enclosing side wall; wherein said over-mold housing being a unified body and comprising soft magnet material; wherein said substrate and said over-mold housing forming a cavity for encasing said movable body; wherein said switching magnet is controllable to cause said movable body settling in a stable state related to said substrate wherein said stable state is selected from: a) said first set of movable contacts being in contact with said first set of stationary contacts and said second set of movable contacts being separated from said second set of stationary contacts; b) said first set of movable contacts being separated from said first set of stationary contacts and said second set of movable contacts being in contact with said second set of stationary contacts; or c) said first set of movable contacts being separated from said first set of stationary contacts and said second set of movable contacts being separated from said second set of stationary contacts.
