When choosing an electronic centrifugal switch, the following factors need to be considered:

1. Rated current and power: Select an electronic centrifugal switch that matches the motor current and power. Generally, the rated current of the centrifugal switch should be greater than or equal to the rated current of the motor, and the rated power of the centrifugal switch should also match the rated power of the motor.

2. Working speed: The working speed of the centrifugal switch should be adapted to the speed of the motor. In general, the centrifugal switch should automatically turn on the power when the starting speed of the motor reaches a certain value, and automatically cut off the power when the motor speed drops to a certain value.

3. Mechanical life: The mechanical life of the centrifugal switch refers to the number of times that the switch can be completed under certain conditions. The higher the mechanical life, the better the durability of the switch.

4. Operation performance: Select the centrifugal switch with simple operation and stable performance, which can improve the efficiency and safety of use.

5. Environmental conditions: Consider the environmental conditions under which the centrifugal switch works, such as temperature, humidity, vibration, etc., and select the centrifugal switch suitable for these conditions.

6. Brand and price: Choose well-known brands and reliable quality centrifugal switches, and give priority to quality and performance indicators when the price is reasonable.

To sum up, the above factors need to be considered when selecting an electronic centrifugal switch to ensure that the centrifugal switch can work safely and reliably, and improve the efficiency and stability of the entire system.
