Abstract: An apparatus and method are provided for sensing the position of a point of contact through use of a sensor having a movable element, disposed between a sensing element and a source of magnetic flux, and having an aperture therein for allowing a portion of the magnetic flux from the source of magnetic flux to pass through the aperture and impinge on the sensing element. The aperture may have various shapes to provide a desired linear or non-linear relationship between the position of the movable element and the intensity of the flux that passes through the aperture and impinges on the sensing element for a given position of the movable element.
