How to distinguish between good and bad home switches, and how about home switches

Identify the good and bad sockets from the following aspects.

1. Identification. The national standard requires that the socket must have the word "max" or "maximum", indicating the maximum power or current that the socket can withstand, and consumers must choose the appropriate socket according to the power of the electrical appliance. In addition, there must be a 3C mark on the wire and plug.

The 3C logo is not required on the socket.

Second, appearance. Generally, good products have a smooth appearance, uniform color, clear printing, and the materials used have certain hardness and flame retardant requirements, which look textured; However, although the surface of some products is smooth and clean, it seems to be coated with a layer of oil, but the weight is very light, and the flame retardancy of such materials is not good, which will bury fire hazards for household electricity.

3. Hand feel. When buying a socket, shake it with your hand first, there should be no sound inside, and there should be a sense of thickness; Then pull the power cord by hand, and the connection between the power cord and the socket should be strong and reliable. If it is a socket with a switch, you need to try to press it a few times, there should be no stagnation, and the sound should be crisp; Finally, insert the plug into each jack of the socket, and the insertion and unplugging force of each jack should be uniform and moderate, too tight or too loose will affect its normal use.

Fourth, structure and materials. The socket is the most important part that affects the quality of the socket, and the socket can be seen from the jack. Under normal circumstances, the material is treated with nickel plating with phosphor bronze, the surface is smooth and clean, there is no patina, the thickness is generally between, and the copper sheet is pulled out, which feels elastic; If it is possible to open the back cover, and then carefully observe the internal structure of the socket, the internal connection wire should be thick, the solder should be even, and there can be no false soldering.

The cross-sectional area of the power cord is also an important factor affecting the quality of the socket and must be consistent with the nominal cross-sectional area. If the cross-sectional area of the power cord is too small, long-term use will cause the power cord to heat up and become soft, and in severe cases, it will cause a disaster.

Fifth, recognize the brand. Famous brand products have passed the strict test of time and market, and both materials and production have undergone strict quality inspection. At the same time, it is recommended that consumers buy sockets in regular shopping malls to avoid counterfeit and shoddy products.

Finally, consumers are reminded not to use multiple high-power electrical appliances at the same time on a plug bulge, and must calculate that the sum of the power of the connected electrical appliances must be less than or equal to the maximum allowable power marked on the socket before use, so as not to overload the socket and avoid causing accidents.

How to choose a good switch socket.

Switches and sockets are very detailed and tiny parts of the whole home decoration process, but they are the "lifeblood" of home safety electricity, and their importance is self-evident. Nowadays, people's definition of quality of life has gradually shifted from the size of the living space to the advantages and disadvantages of the details of home furnishing products, among which the quality of the switch panel is one that cannot be ignored. A good switch socket not only ensures the safety and comfort of daily use, but also brings a distinctive decorative effect to the home with its highly designed appearance.

How to choose a high-quality switch socket, and what aspects need to be paid attention to when choosing? Technical experts from Schneider Electric will give you a detailed explanation of the inner and outer doorways of the switch socket.

It is recommended to choose the brand! ***！

Hello! 1. Look at the appearance.

The style and grade of the switch should be consistent with the overall style of the interior. White switches are the mainstream, and the overall tone of most interior decorations is light, and in most cases, dark switches such as black and brown should not be used.

2. By feel.

Most of the high-quality switches are made of bulletproof glue (PC) and other advanced engineering plastics, with good fire performance (flame retardant), moisture-proof performance, impact resistance, ultraviolet resistance, etc., and good surface texture. Generally speaking, products with a rough surface and a thin, brittle feel to the touch cannot be trusted in various properties. The panel of a good switch socket requires no bubbles, no scratches, and no smudges.

The switch toggle feels light and not tight, the jack of the socket needs to be equipped with a protective door, and the plug should require a certain amount of force and cannot be inserted with one foot.

3. Weigh the portions.

When buying a switch, you should also weigh the weight of the individual switch. High-grade switch socket should have enough weight, high-end products generally will not cut corners, very light products must have the suspicion of cutting corners, should be cautious when purchasing, because only the copper inside the switch is thick, the weight of a single switch will be heavy, and the copper inside is the most critical part of the switch, if it is alloy or thin copper will not have the same weight and quality.

4. Choose a brand manufacturer.

It is best to choose products from regular and professional manufacturers. Because the quality of the switch is related to the normal use of electrical appliances, and even the convenience of life. The switches produced by many small manufacturers are sometimes very unreliable, and it doesn't take long at all, and it is obviously very troublesome to replace them frequently; But there are also some well-known brands that are not professional switch and socket manufacturers, and even some are OEM to small factories, and the product quality can not be fully controlled, so when purchasing products, we should choose regular and professional manufacturers' products, and regular products will generally make effective commitments to consumers, such as "guarantee 12 years of service life", "can be continuously switched on and off 40,000 times" and so on.

5. Choose service.

As far as possible, go to the store or sales point designated by the regular manufacturer to buy, and keep the shopping voucher, so as to ensure that you can enjoy the after-sales service in the future.

6. Look at the logo.

Pay attention to the necessary identification on the base of switches and sockets: such as national compulsory product certification (CCC), rated current and voltage value; Product model, origin (made in China), wiring identification, etc.

7. Look at the packaging.

The product packaging should be standardized and complete, the design and printing should be exquisite, and there should be a clear trademark, manufacturer's address, **, company** and other information, including instructions for use and certificates, accessories and screws, etc.

Hope it works for you.
