Second, the selection method of multifunctional socket

1, depending on the quality:

The quality of switch socket is related to the safety of household electricity. Some products certified by authoritative testing institutions such as the Electrotechnical Commission are reliable. You can ask the salesperson about this situation. It would be better if you could provide a copy. At the same time, you can also ask about the internal materials of switches and sockets. The conductive parts of high-quality products should be phosphor bronze, and the contacts should be composite silver.

2. Look at the structure:

Some imported or joint venture products cancel the traditional screw pressing and adopt the pressure plate terminal, which can increase the contact area of the conductor, improve the conductivity and avoid the screw crushing the core wire, and can be used for single-core and multi-core conductors.

3. Look at the brand:

We encourage you to choose famous brands, because the quality of switches is related to the normal use of electrical appliances and even the convenience of life. Most brands will make effective promises to you, such as "availability 15 years" and "guarantee 12 years".

4. Look at this sign:

Pay attention to the signs on the switch socket base, including 3C certification and rated current and voltage.

5, look at the feel:

The switches with good quality are mostly made of advanced materials such as bulletproof rubber, which have high fireproof performance, moisture-proof performance, impact resistance and smooth surface.

6. Look at the price:

Domestic switch sockets are low in price, but few are excellent in quality; The price of imported brands is mostly tens of yuan, and joint venture products are a good choice. The quality, function and style are almost the same as those of imported products, but the price is only half.

7. Look at the service:

As far as possible, go to the store or point of sale designated by regular manufacturers to buy and ask for invoices, so as to ensure that you can enjoy after-sales service in the future.

8. Look at the package:

There should be a clear manufacturer's address and telephone number on the product packaging, with instructions and certificates.

Everyone should pay attention to the standard of multifunctional sockets when purchasing multifunctional sockets, so as to avoid buying inappropriate sockets and damaging household appliances at home.
