  • Patent number: 10158310
    Abstract: An electronic switch and an electronic device are disclosed. The electronic switch includes a trigger, a measurement device, a load control circuit, and the controller. The trigger switches on or off a circuit between a power supply and the electronic switch and generates the travel of the electronic switch. The measurement device is configured to measure working parameters of the power supply, the load and the trigger and to send the working parameters to the controller. The controller receives the working parameters and generates a control signal with a PWM signal. The PWM signal is obtained by adjusting the current control signal according to the working parameters. The control signal is sent to the load control circuit. The load control circuit controls the rotation speed of the motor in the load with the control signal.

  • Patent number: 10158311
    Abstract: An electronic switch control method is disclosed. The method comprises receiving the current working parameters of the electronic switch, then reading duty cycle parameters matching with the current working parameters; conducting a linear calculation with the duty cycle parameters and the working parameters to obtain a new duty cycle; adjusting the current control signal to obtain a PWM signal having the new duty cycle; and controlling the rotation speed of the motor in a load with the PWM signal. 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.
