Abstract: A switching device for an electric motor comprises a fixed body, at least one moveable body that can be moved with respect to the fixed body between at least one first and one second position, in which the phases (104, 105, 016) are respectively in a first and a second electrical configuration, and a moving unit configured to move said moveable body between the first and the second position. This moving unit can be selectively coupled to the rotor of the electric motor so as to rotate with it and comprises a selecting device operationally placed between the rotor and the moveable body of the switching device and configured to transform each revolution of the rotor into a movement of the moveable body between the first and the second position.
