<p>A control mechanism comprising a casing, an operating lever (l) projecting at the top from the casing and arranged to swivel omnidirectionally against a spring-produced resetting force, and at least two transducers arranged according to two orthogonal axes for producing signals being a measure for the magnitude of the swivelling angle and for the swivelling direction of the operating lever (l). The operating lever (l) is mounted near its lower end in a ball joint (2) received in the upper wall of the casing, with the free lower end of the lever (l) abutting on four spring elements (3,6,9,l2) whose lines of action (X,Y) coincide two by two intersect each other at right angles. The spring elements (3,6,9,l2) are connected at the lower end of the operating lever (l) to downwardly extending oscillating or wagging plates (5,8,ll,l4) whose ends (A,B), upon swivelling movement of lever (l), are displaced inwardly in the direction of the axis of the casing. The magnitude of this displacement is a measure for the swivelling angle and the swivelling direction of lever (l).</p> |
