<p>The control unit has an operating lever (12) which tilts around a first axis, and has two stops (20). Two centering levers (22) can rotate around the lever shaft, and carry two adjustable stops (24) that come into contact with the operating lever stops. Springs (30) are connected between each centering lever and the housing, and these push the centering levers against the stops on the operating lever.</p> |
