ABSTRACT:
A control lever assembly having a moveable lever and a knob mounted on an end of the lever. The knob has a hollow housing which is removably attached to a cylindrical base. The housing has a cylindrical side wall which forms an opening. A wheel is received in and partially enclosed by the housing for rotation therein. A portion of the housing completely surrounds an outer surface of one end of the wheel. A rotary encoder generates a rotary position signal and is coupled to the wheel by a stiff wire or shaft. The shaft extends through the wheel to a first end which is received by an alignment recess formed on an inner surface of the housing and to a second end which is coupled to the encoder. The shaft extends through a bore in the base and through a bore in the lever.
