  • Patent number: 11641170
    Abstract: A power tool includes a motor, a signal switch, a signal detection circuit, a power-on control switch, a first controller, and a second controller. The signal switch is used to switch a power on/off state of the power tool. The signal detection circuit is configured to output a detection signal according to a connection state of the signal switch. The power-on control switch is connected to the second controller. The first controller is configured to control an on/off state of the power-on control switch. When the signal detection circuit outputs a power-off signal, the first controller controls the power-on control switch to be turned off so that the second controller is de-energized and the motor stops rotating. When the power-on control switch still remains on, the second controller controls the switch elements in the driver circuit to be turned off so that the motor stops rotating.
