People who have been involved in home improvement have such experience. The size of the switches, both large and small, looks almost the same. However, the price difference is very large. It is as low as a few dollars and as high as a few hundred dollars. How about switching sockets? Experts tell you that the reliability of the choice of switch socket is the most important, we must choose the quality of the brand. Looking at the problem, some of the products that have been certified by an authoritative testing institute such as the Electrotechnical Commission can be trusted. Consumers can ask salespeople about this situation, and it would be better if they could provide copies. At the same time, the internal materials of the switch and the socket can also be inquired. The conductive parts of high-quality products should be phosphor bronze, and the contacts should be composite silver. Second, look at the hand. Most of the good quality switches are made of high-grade materials such as ballistic rubber. The fireproof performance, moisture resistance, and impact resistance are all high. The surface is smooth. Three look at the structure. Some imported or joint-ventured products have eliminated the traditional screw press lines, while the use of plate-type terminal blocks, which can increase the contact area of ​​the wire, improve the conductivity, avoid the screw crush the core wire, and single core, multi-core wire can be used . Four to see the price. The price of domestically produced switches and sockets is relatively low, but the quality is not much; the prices of imported brands are mostly tens of yuan. The joint venture product is a good choice, quality and function, style are almost the same as imported products, but the price is only half. Five to see the brand. We encourage you to use well-known brands. Because the quality of the switch is related to the normal use of electrical appliances, and even the convenience of living. Most brands will want consumers to make effective commitments, such as "available 15 years", "guarantee 12 years of life," and so on. Six look service. As far as possible to the regular factory designated store or point of sale to purchase, and ask for an invoice, so as to ensure that you can enjoy future service. Seven to see the logo.
