description The utility model relates to a voltage reduction starting time-delay circuit, which is characterized in that a resistor R1, a capacitor C2 and a voltage stabilizing diode D2 form a power supply circuit to provide 12V voltage for a 555 timer, the cathode of the voltage stabilizing diode D2 is connected with the anode of the capacitor C2, the anode of the voltage stabilizing diode D2 is connected with the cathode of a capacitor C1 and is grounded, the anode of the capacitor C1 is connected with a 12V power supply, the cathode of the capacitor C1 is connected with one end of a resistor R2, and the other end of the resistor R2 is connected with a power supply. The other end of the resistor R2 is connected with a potentiometer W1, the other end of the potentiometer W1 is grounded, pins 2 and 6 of the 555 timer are connected together and then are connected with the negative electrode of a capacitor C1, pins 4 and 8 of the 555 timer are connected with the cathode of a voltage stabilizing diode D2, a pin 1 is grounde
