The control circuit for self-turn-off of an automatic machine, connectable to a domestic voltage power line (L1, L2), comprises a logic controller (1) having low electric power supply voltage, a power supply (2) for the logic controller (1), at least one switch (3) to control at least one electrical load (4, 5) of the machine, connected to the logic controller (1), an electrically actuated deviator (6) connected to the logic controller (1) and switchable between machine activation status, in which a main electric power line (7) of the power supply (2) is connected to the power line (L1, L2), and machine deactivation status, in which a secondary electric power line (8) of the power supply (2) is connected to the power line (L1, L2), having a switch (9) normally open activatable by a manual reactivation button on the machine, said normally open switch (9) being connected to the logic controller (1), and electrical energy storage means for maintaining the electric power supply of the logic controller (1) for the entire operating time of the deviator (6) switching, automatically generated by the closure of t e reactivation switch (9), from machine deactivation status to activation status.
