Abstract (en)

A control device (1) for controlling the operation of a mechanic, electric, pneumatic, hydraulic/oleodynamic, or similar user comprising a basic body (2) in the middle of which a rotating shaft (10) torsionally coupled with a rotating knob (19) which rotates on said basic body (2) is installed, such shaft (10) being functionally connected to electric connectors suitable for supplying electric power to said user when the knob (19) is in a first operating position on said body and for interrupting said supplying of electric power when the knob is in a second operating position on said body. The knob (19) supports a selector member (40) for selecting the movement of the knob (19) on said basic body (2), said selector member (40) being torsionally integral with the knob (19), but rather being movable orthogonally to it, said selector member (40) comprising interception means (42) suitable for cooperating with counter-interception means (35) provided in said basic body (2), the cooperation between such interception means and counter-interception means (42, 35) preventing the rotation of the knob (19) placed on said basic body (2), the separation of such interception means and counter-interception means (42, 35) making it possible the knob (19) to rotate from the first operating position towards the second operating position and vice-versa.
