Abstract
A rotation-sensing device for providing output signals that correspond to rotary hand movement made about the device by an operator is disclosed. The device comprises a cover member including an outer surface having a generally cylindrical, longitudinally elongate, non-rotatable protusion carried thereon. The protrusion projects outwardly from the outer surface and is provided with an outer periphery thereon. The device further includes a plurality of generally longitudinally elongate, circumferentially spaced, sensing means which are positioned adjacent the outer periphery of the protrusion and are responsive to the rotary hand movement of the operator for providing output signals corresponding to such movement. In addition, the device includes means coupled to the sensing means for leading the signals generated in the sensing means away from the switch device.
