US Patent 10362897 Control circuit for self-turn-off of an automatic machine

A control circuit, connectable to a domestic power line (L1, L2), includes a logic controller (1), a power supply (2) for the logic controller (1), at least one control switch (3) for an electrical load (4, 5) connected to the logic controller (1), and an electrically actuated deviator (6) connected to the logic controller (1). The deviator (6) is switchable between a machine activation status, where a main power line (7) of the power supply (2) is connected to the domestic power line (L1, L2), and a machine deactivation status, where a secondary power line (8) of the power supply (2) is connected to the domestic power line (L1, L2), having a normally open switch (9) connected to the logic controller (1), and energy storage that maintains power supply to the logic controller (1) for an operating time of the deviator (6) switching.
