The correct name for an air switch is called an air circuit breaker, which is usually used for overload or short circuit protection. It is no exaggeration to say that the electrical safety of almost every family is inseparable from the protection of the air switch, not to mention the development of industrial production and technology. Understanding and being familiar with the basic principles and performance of the air switch is the knowledge that every owner needs to know.

The air switch is a very common protective electrical component. Air switches are widely used in industry and life. As long as the circuit does not exceed the allowable current of the air switch, even if there is leakage, the air switch will not automatically trip to cut off the power in the circuit.
