Abstract (en)
A motorized control (1) for low-voltage switches, comprising a servomechanism (10), a control unit (20), and a coupling lever (30) associated to said servomechanism (10) and to a switch. The servomechanism (10) is controlled through impulse signals sent by the control unit (20) and performs pre-defined rotations that enable a movement of the coupling lever (30) between two pre-set positions characteristic of a condition in which the switch opens the circuit and a condition in which the switch closes the circuit.
