Patent ID: 8653913

Claim:
A contact system comprising: at least one first contact; at least one second contact; at least one movable contact, the at least one movable contact being movable between the at least one first contact and the at least one second contact; a coil which, when energized generates a force which attracts the at least one movable contact to the at least one first contact; a magnet having a magnetic force, the magnet attracts the at least one movable contact to the at least one first contact, the force generated by the coil and the magnetic force of the magnet causes the at least one movable contact to move against the at least one first contact with a first contact force; a return spring having a spring force, the return spring cooperates with the at least one movable contact to return the at least one movable contact to the at least one second contact when the coil is not energized, the force generated by the return spring causes the at least one movable contact to move against the at least one second contact with a second contact force, the first contact force and the second contact force being essentially identical; whereby the sum of the forces applied by the coil and the magnet are sufficient to overcome the spring force of the return spring to provide a balanced force to both the at least one second contact and the at least one first contact, yielding an essentially identical voltage drop when the at least one movable contact is moved against the at least one first contact or the at least one second contact.
