Schneider switch TCL switch look at the appearance

first check the outer packaging. The packaging and printing of high-quality sockets are clear, the information is complete, and the formal inquiry telephone number is indicated; However, inferior sockets are poorly packaged, and the printing is ambiguous. Some of them even lack the most basic manufacturer and product information, or use the wrong inquiry phone to deceive consumers

if there is no problem with the outer packaging, next look at the shell panel. High quality sockets, such as bull socket, are fine in workmanship, with even particles on the frosted surface, glossy surface, and no burrs and flash around the shell and the socket edge; The frosted surface of inferior socket has uneven particles, the smooth surface has no gloss, there are many burrs and fins, and the workmanship is rough. In addition, the shell of high-quality sockets is marked with clear anti-counterfeiting marks or identification methods, while most low-quality sockets have no formal anti-counterfeiting marks

secondly, check the plug. Bull sockets with three pole jacks are all equipped with three pole plugs. In addition to the zero line and live line, they also have grounding electrodes, which can effectively prevent electric shock and ensure safety; Many inferior sockets, although containing three pole jacks, are only equipped with two pole plugs without grounding electrodes, which is very easy to cause electric shock accidents

finally, consumers can also look into the jack and observe the copper strip of the guide. The copper strip of high-quality socket such as bull socket is thick, the coating is uniform and bright, and the color is consistent; And inferior sockets mostly use inferior copper, which is very thin, the surface has not been treated, and the color is uneven. Some inferior sockets look “ Copper ” It is very thick. In fact, it is nickel plated on the iron sheet, which is easy to rust, poor conductivity, high calorific value and great potential safety hazards

second inspection of hand feeling

after seeing the outer packaging and product appearance, hand feeling inspection is also very critical

first, try to press the socket switch several times. The switch of the high-quality socket has a moderate feel, opens and closes freely, light but not tight, and the sound is crisp; The poor quality socket feels stiff and easy to jam

secondly, experience the plug-in feel. The high-quality socket not only has a moderate plug-in feel of a single hole, but also the plug-in feel of each jack is basically the same; The plugging force of inferior sockets is too loose or tight, and the elasticity is poor, and the hand feeling of each hole is also significantly different

in addition, pull the power cord, the power cord of the high-quality socket feels soft and hard, and the connection with the socket is solid and reliable; The power cord of the inferior socket has a soft feel, and is not firmly connected with the socket, which is very easy to pull off

three recognition brands

“ One look and two tests ” After that, consumers should also choose socket products of large manufacturers and brands. Big brands are more trustworthy after many tests of time and market. Inferior sockets and Shanzhai brands lack professional R & D, production and testing equipment and standardized quality control standards, resulting in great hidden dangers in power safety

the above three tips are simple and practical. Consumers can use them to accurately select high-quality sockets to avoid “ Lose big for small &rdquo
