Analysis of the material of the switch and socket

The material is not good. The quality of the switch is unlikely to meet national standards. The internal copper parts of the switch are made of pure copper. The diameter of the silver contacts is 4mm or larger. The housing is made of flame retardant PC material. (Too much pulling and inserting force will result in too little pulling and inserting force.) 0.6mm is reasonable; sockets must have safety doors and their structure must meet the requirements of national standards.

According to the relevant electrical material standards, the characteristics of commonly used villa switch materials should satisfy: 1. High electrical insulation strength; 2. Flame retardant, high temperature resistant, low temperature resistant, suitable for large temperature difference; 3. Good impact resistance.

For the panel of the villa switch, the surface colour is also required to be uniform and oxidation-resistant. For example, the generic name of the backseat: PBT (scientific name: polybutylene terephthalate), which is not easy to break.

Therefore, the materials used in conventional villa switches are not ordinary plastics. In order to reduce costs, informal manufacturers and small workshops often use ordinary plastics or even recycled plastics.

The socket has a safety door design. If equipped with this design, it effectively prevents babies in the house from accidentally plugging in and receiving electric shocks, and also greatly improves the safety of the socket. It also keeps pests and dust out. You will find a key wide enough to be inserted into the individual holes. If you can't easily break through the barrier of a protective door, it means you can effectively keep your family safe.

The PC material is known as polycarbonate, also known as ballistic rubber. It is extremely heat-resistant, flame-retardant and highly impact-resistant, and even after long periods of use, it is very resistant to UV rays. Does not change colour. In the market, the middle and high-end brands of switch products will use PC material as the panel material, and international brands also use PC material as the bottom shell of the functional parts at the back of the product to improve product safety more comprehensively.

It seems that metal villa switches are more popular now! Brushed metal villa switches are more popular in the market because of their very high-grade appearance and relatively diverse colours, which can be adapted to various decorative styles. However, I don't think that when choosing an upscale villa, you can't just look at the appearance, but you also need to understand the quality, especially in terms of safety, and check the markings and materials. Product. This is something that newbies need to be aware of. For some of you who know the material, you can check the internal structure and material, which is also a part of judging the quality of the villa switch.
