1. A circuit breaker assembly, comprising:
a mechanism configured to be actuated by an operator toward a first position, wherein the mechanism is configured to move between the first position and a second position to change a state of a contactor between a closed state and an open state;
a magnetic coupler disposed on, within, or forming a portion of the mechanism;
a primary inductor disposed in magnetic proximity to the magnetic coupler, wherein the primary inductor is configured to receive an input signal and configured to generate a reference magnetic field;
a sense inductor disposed to be in magnetic communication with the magnetic coupler and/or the primary inductor, wherein the mechanism is configured to move the magnetic coupler relative to the sense inductor and the primary inductor, and wherein the sense inductor is configured to sense a magnetic field flux, wherein a relative position of the magnetic coupler affects the reference magnetic field to effect the magnetic field flux sensed by the sense inductor, wherein the sense inductor and the primary inductor are planar coils that are concentric; and
a position sensor system configured to sense a position of the mechanism between the first position and the second position.
