There are many kinds ofswitches on the market, not only in various styles, but also in different prices. The cheap ones are as low as a few pieces, and the expensive ones are hundreds of dollars. In fact, the expensive ones are not necessarily of good quality. The main thing is whether consumers will identify them. . Usually the quality of foreign trade switches is the best, but it is also the easiest to “deceive” consumers. This is because some profiteers decorate inferior switches with exquisite packaging in order to make huge profits, which not only has low cost performance, but also greatly increases the hidden dangers of safety. How should we identify whether the foreign trade switches on the market are true or false? Let’s take a look at what a good quality switch looks like!
The shell material used for the switch with good quality is PC material. The switch made of this material has a good feel, is not easy to change color, and has strong impact resistance and high temperature resistance. Generally, PC material cannot be produced in China, and low-cost black is often used Nylon material. The second thing to look at is the copper material. We can see from the socket. If it is yellow, it is a switch socket of poor quality. If it is purple, it is a high-grade switch. This is because the brass The texture is soft and easy to rust. As long as it is used for a long time, the electrical conductivity will be greatly reduced; while the purple-red copper sheet has a hard texture and is not easy to rust, and its service life is greatly extended.
