A magnetic switch controlled circuit for an electrical appliance includes a voltage input terminal, a voltage output terminal, a magnetic switch, a relay circuitry and a turn-off delay circuitry. When the magnetic switch detects a first change in the magnetic field from an idle status, the relay circuitry is configured to output an output voltage to the voltage output terminal so as to supply power to the electrical appliance. When the magnetic switch detects a second change in the magnetic field from the first change in the magnetic field, the turn-off delay circuitry is configured to control the relay circuitry to continue outputting the output voltage to the voltage output terminal for a predetermined period of time, the relay circuitry being switched off by the turn-off delay circuitry after the predetermined period of time elapses.
