1. Ship switches, also known as rocker switches and rocker switches, have different ability to cut off current: ordinary circuit breakers can withstand very large loads and short circuit currents.

2. Air switch usually plays the role of "isolation" and "protection device" in small current circuit, also called automatic switch, also called air circuit breaker;

3. Ship type switch, also known as rocker switch and rocker switch, has good arc extinguishing ability, and will automatically trip in case of short circuit and high current; In high voltage and large current circuits, it is often used as an operating appliance for power cut, power transmission, and load connection and disconnection;

4. Difference of voltage grade: The common voltage grade of ordinary air switch is below 500V, while the circuit breaker can be used for all voltage grades above 220V
