Selection skill

Look at the brand

According to incomplete statistics, there are more than 1500 enterprises producing switch socket products in China, and the quality difference between products is huge. Because many ordinary consumers don't have a way to identify the quality of products, and their understanding of switch socket brands is limited, some unscrupulous businessmen have a living space, and some fake and shoddy products flow into the market. Of course, many large enterprises attach great importance to their own brand image, have higher requirements for product quality and relatively guaranteed after-sales service. Quality assurance is usually not less than 65,438+02 years. Therefore, in order to use it safely, it is best to choose a big company or a reputable brand for the switch socket.

Check the appearance

The panel shall be uniform in color and smooth in surface, and free from dents, mottled colors, bubbles, stains, cracks, expansion, lack of glue, deformation, scratches, shrinkage and other defects. Metal parts should be free of burrs, cracks, corrosion marks, rust and screw head damage.

consider

You should also weigh the weight when buying a switch socket. If merchants choose thin copper sheets, they will feel lighter. Good switch sockets usually use thicker and heavier copper sheets and terminals. Copper is the key part of switch socket, and it is also the key part to identify counterfeit and shoddy products. Consumers should also pay attention when purchasing: some unscrupulous manufacturers will add iron plates to their products to increase their weight, so they must look carefully when purchasing.

Prominent position

Different places should be equipped with different kinds of switches and sockets. There is often water and oil smoke in the kitchen and bathroom. It is best to install splash box or plastic baffle on the socket panel, which can effectively prevent short circuit caused by oil pollution and water vapor intrusion. In families with children, in order to prevent children from touching the socket hole with their fingers or poking with metal objects, parents had better choose a safety socket with safety protection devices.

Socket is very common in our life and plays a very important role. The most common ones are mobile sockets, fixed sockets, multi-position sockets, electrical sockets and so on. But there are too many kinds and brands of sockets on the market now. So many friends don't know how to buy it. In any case, safety must be put in the first place when buying sockets, so as to ensure the safety of electricity use.
