The manipulator delivers signals characteristic of the orientation of an operating lever (2) in space. The lever is deflectable by a transverse thrust, from a reference or neutral position, and is elastically returned to that neutral position. The lever (2) is articulated on a casing to control the position of at least one movable member (3) interacting with at least one pick-up (4) to deliver an electrical signal dependent upon the position of the lever. Two cams (7, 8) resiliently biased toward each other oppose to the angular deflection of the operating lever (2) an elastic reaction which differs according to the orientation of the lever (2) with respect to its neutral position. In an embodiment, these cams are carried respectively by a ball joint of the lever and by a piston slidable in the casing and urged by a spring.
In a manipulator delivering signals characteristic of the orientation of a lever in space, such lever being movable, under transverse pressure, from a reference or neutral position, and elastically returned to said neutral position, said manipulator comprising a casing, a bearing surface stationary with said casing, a ball joint carried by said lever and resiliently urged against said bearing surface, said lever being connected to at least one movable member interacting with at least one pick-up for delivering an electrical signal responsive to the orientation of the lever, means resiliently opposing the angular displacement of said lever from its neutral position;
