Abstract
A knob body is provided for a control lever. The knob body includes a lower segment, and an upper segment. The lower segment extends out from a vertical axis of the control lever and includes a pair of upright protrusions extending out from an upper portion thereof. The protrusions define a gap therebetween. The lower segment further includes a movable switch located within the gap. The lower segment further includes a first actuation switch disposed on a sidewall of the lower segment. The upper segment is disposed about the vertical axis and is located proximate to the upper portion of the lower segment. The upper segment is in a spaced relationship relative to the protrusions. The upper segment includes a locking switch that is operable to allow selective movement of the control lever, and a second actuation switch that is provided on a sidewall of the upper segment.
