How to connect the upper and lower switches?

Switch is a relatively large power switch, leakage protection switch, also known as knife. It is a switching device mainly used for "isolating power supply, switching operation, connecting and cutting off small current loop" and has no arc extinguishing function.

When the switch is in position, there is an insulation distance between the contacts that meets the specified requirements and obvious disconnection signs; When in the closed position, it can withstand the current under normal loop conditions and the current under abnormal conditions (such as short circuit) within the specified time.

Precautions for switch

Generally speaking, most switches choose plastic materials to avoid conduction. This makes the switch easy to be damaged. If a family member trips for no reason, then check whether it is a switch problem. Once the switch is found to be damaged, it should be replaced in time.

In fact, overload is the most common cause of tripping. With the gradual increase of household electrical equipment, the voltage borne by the line is also increasing. If this problem is not taken into account in the initial wiring, resulting in a small line capacity, then there will be a trip caused by line overload.
