Abstract
A joystick comprises an articulation comprising bearing faces that are shaped to permit, via shape-shape interaction when they rub against each other, a rotational movement of a handle. A first set of springs exerts, on the handle, a first vertical force that pushes the bearing faces against each other. A second set of springs exerts, on the handle, a second vertical force in the opposite direction to the first vertical force and the amplitude of which is between 0.9|F| and 1.1|F|, wherein |F| is the amplitude of the first vertical force. The first and second sets of springs are able, in the absence of external stress on the handle, to maintain a non-zero clearance between all the bearing faces of the articulation.
