The reasons for short circuits in switch sockets are as follows:

It depends on whether there is a mark that has passed the metrological certification of the national technical supervision department. The testing unit is only qualified to conduct testing after passing the metrological certification, and the report it presents has legal effect.

Date of issuance for inspection and testing. At present, China's building material production enterprises basically follow the 10 standards for "harmful substance limits for indoor decoration materials" in terms of testing. This standard was forcibly implemented by relevant departments such as the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China on January 1, 2002. Consumers should check whether the 10 new national building materials standards have been used for the testing standards and basis from the testing report.

Check if the tested product has the same name and specifications as the selected product. Some manufacturers may produce dozens of building materials products at the same time, with different product formulas and production processes, and varying levels of harmful substances.

During the installation of the lamp holder, twisting the lamp holder causes the wires to twist together, or there are too many exposed wire cores that come loose and touch the other end, causing a short circuit and fire.

Improper installation of the switch, especially when the switch is installed on a combustible object, the sheath at the wire outlet is scratched, causing the wire core to be exposed or water vapor to seep in. Improper installation of the switch, or electric moving arc insertion when the switch is disconnected, causing a fire. When the power distribution board is not in the box and the fuse blows, hot metal particles may splash off, causing combustible materials below to ignite. When combustible gas used in households leaks from pipelines or valves, causing it to mix with air and reach an explosion point, opening or closing electrical switches without arc extinguishing devices will generate sparks, causing a fire or explosion.
