The working principle of the electronic centrifugal switch is to sense the speed of the motor through the electronic sensor and the control circuit, and automatically disconnect or switch on the circuit when the motor reaches the preset speed. It does not rely on mechanical motion or centrifugal force, but uses electronic means to control the start and stop of the motor. Specifically, the electronic centrifugal switch controls the start, run and stop of the motor by detecting the speed of the motor. When the motor starts, the electronic centrifugal switch will detect the speed of the motor. If the speed of the motor reaches the set value, the electronic centrifugal switch will automatically switch to the running state and the motor will start to work. When the motor is running, the electronic centrifugal switch will constantly detect the speed of the motor. If the speed of the motor is lower than the set value, the electronic centrifugal switch will automatically switch to the stop state and stop the operation of the motor.
