1. the difference between the load switch and the electrical isolation switch is that the load switch has an arc extinguishing device, and the electrical isolation switch does not have such a device. So is there any difference between the arc extinguishing device and the arc extinguishing device? The so-called arc extinguishing device is in order to better help to switch off and shut down, but also can effectively limit the arc, to help the arc out. There is such an arc extinguishing device, it is safer for the switch. Therefore, most of the switches are made of arc extinguishing devices. Especially for home appliances. Therefore, most of the switches are made of arc extinguishing devices. Especially for home appliances.

2. the difference between the load switch and the electrical isolation switch is that the difference between the second cuts is that the current is cut off. Because the isolation switch no arcing device, it is only suitable for cutting off the current load, to cut off the load current and short-circuit current, so isolating switch appliances can only operate in the safety circuit safety off, and is strict with load operation, to avoid accidents. The load switch is capable of overload current and rated load current because of arc extinguishing device, but the same can not be used to cut short circuit current.

3. load switch and electrical isolation switch function differently. Because there is no isolation switch arc extinguishing device, so can only be applied to high voltage circuit devices require a charged part and power part need a separate role, in order to ensure the maintenance and inspection personnel of high voltage circuit, ensure the safety of personnel. The load switch is used in fixed high voltage equipment. It can cut off the fault current and the rated current in the high voltage equipment, so they have different functions, but both of them are applied to the high voltage equipment.
