Abstract

A self centering, angularly displacable joystick allowing multiple compound torque profiles is provided. The self centering joystick includes a first mount and a base. The first mount located a fixed distance away from the base. The joystick extends from a restoring plate having an upper surface and a multi-faceted lower surface pivotally mounted to said first mount to partially rotate about a first axis. A linearly displaceable force plate having a substantially flat upper surface is disposed between said base and said multi-faceted surface, and a spring is provide between the base and the force plate, the spring biasing the force plate against the multi-faceted surface to provide a centering force there against. The multifaceted surface includes a center position facet oriented such that the centering force applied by the force plate is evenly distributed on each side of the first axis when said center position facet is aligned parallel with the upper surface of the force plate.
