摘要： An electronic switch controller, an electronic switch control method, an electronic switch and an electronic device are disclosed. The processor comprises voltage-stabilized power supplies, a processor and a driving circuit; the processor is connected between the voltage-stabilized power supplies and a measurement device to receive working parameters of the power supply, a load and the electronic switch measured by the measurement device, read duty cycle parameters matching with the working parameters, calculate a new duty cycle with the duty cycle parameters and the working parameters, adjust the current control signal to a PWM signal having the new duty cycle, and send the PWM signal to the driving circuit; and the driving circuit is connected between the voltage-stabilized power supplies and the load to control the rotation speed of the motor in the load. By reducing the volume of an electronic switch and achieving a long low-speed travel, the disclosure enables the user to work at an accurate working point with an electronic device.
