Abstract:

A method of sensing a position of a movable component of an operator interface includes a step of receiving a first signal from a first Hall effect sensor and a second signal from a second Hall effect sensor. The method also includes a step of determining the position of the movable component based on the first signal and the second signal if the first and second signals represent expected values. The method includes a further step of determining the position of the movable component based on one of the first and second signals if the other of the first and second signals represents an unexpected value.
