Claim 0:
1. A control device comprising:
a moving portion;
a magnetic element coupled to the moving portion, the magnetic element comprising alternating positive and negative sections configured to generate a magnetic field in a first direction;
at least one magnetic sensing circuit responsive to magnetic fields in a second direction that is angularly offset from the first direction; and
at least one magnetic flux pipe structure configured to conduct the magnetic field generated by the magnetic element and redirect the magnetic field towards the at least one magnetic sensing circuit in the second direction, wherein the at least one magnetic flux pipe structure comprises a mounting portion, a magnetic element coupling portion, and a sensor coupling portion, and wherein the magnetic element coupling portion and the sensor coupling portion are located at opposite ends of the at least one magnetic flux pipe structure, and wherein the mounting portion is attached to a printed circuit board of the control device, and wherein the magnetic element coupling portion is positioned adjacent to the magnetic element and located in a notch in the printed circuit board.
