Abstract
An input device includes a positioning element and a spring member. The positioning element comprises a generally disc shaped member. The spring member is a generally annular shaped spring member that is generally planar and that defines a generally serpentine pattern. The spring member is positioned laterally outward relative to the positioning element and is configured to exert a biasing force radially inwardly toward the positioning element.
