The first lesson: teach you how to identify the "switch authenticity"
Some netizens reported through the Qijia customer service phone that the price of the Langneng switch purchased in a building material market in Yishan Road was lower than that of the group buying online. The netizen provided the receipts and invoices provided by the merchant when buying. Is there really something cheaper than Qijia? Is it genuine? To this end, “Little Qi†came to the first floor of the building materials market according to the information provided by the users. “Switch small appliances area†went straight to the shop that the netizen said and bought it here: Long energy switch luxury series 5-hole socket 5 A telephone plus computer socket 1, TV socket 1. As an outsider, “Xiao Qi†looks like there is no difference in appearance, so he specifically went to find a professional who switched to Longneng. Analysis of these switches and sockets is just a fake.
1, TV socket:
True and false identification from 3 aspects:
(1) From the panel, the color of the genuine product is relatively light, brighter, and the color of the fake product will be darker and darker; the LOGO of the genuine product is very strong and the LOGO of the fake product is rather vague.

(2) The contact point in the middle of the socket is also true and false. The contact point in the middle of the counterfeit goods is made of relatively poor iron sheet. It is very thin. In the course of subsequent use, it will easily come in contact with it, resulting in poor contact. The inner core of the genuine product is made of stainless steel and compared with the counterfeit goods. Obviously wide and thick.

(3) There are obvious differences from the module on the back side. The module behind the authentic product is more delicate, and the fake product module is more rough. The touch panel behind the switch is also an important part of the switch. A good touch panel is made of aluminum-zinc alloy. The contact is made of silver alloy. The module behind the fake can be seen very rough, with contacts and contacts. It is also done with poor iron sheet.

Summary: Don't look at the appearance of these sockets looks like a model, but there are hidden secrets inside. The main cost of the switch panel is focused on the metal inside. The metal inside the famous brand switch panel is basically copper or stainless steel. With the continuous rise in metal prices in recent years, those fake and shoddy products are replaced with inferior iron pieces. From the outside, it is almost impossible to distinguish between true and false, but the service life and safety are certainly not as good as it should be.
So once again to remind consumers, the switch panel in the decoration is related to the circuit components, do not look at it is a small thing, if misuse of fake and shoddy products, will leave a lot of security risks. The inconvenience caused by the use of electrical appliances is limited, and electrical leakage and injury are even more serious and even cause fires. Don’t be fooled by cheap money. At the same time, you must be vigilant and careful in identifying and guarding against fraud.
