The most used plastics for the panels of household wall switch sockets are ABS engineering plastics, imported PC materials and a new type of material "alloy material". And the most used base is nylon and PC materials.

PC material has a scientific name called polycarbonate, which is an amorphous thermoplastic resin with excellent comprehensive properties. PC material has excellent electrical insulation, extensibility, and very strong impact resistance, good toughness, and very bright color. In addition, PC material has no peculiar smell, heat resistance and cold resistance are also very good. Nowadays, the price of large-scale production and easy-to-process PC materials in industry is more affordable. Based on its various good characteristics, it can meet various needs from mobile phones to bulletproof glass. Therefore, the quality of the switch sockets made of PC materials is very good, and the surface is bright, without roughness to the touch, and the most important thing is that it has a certain flame resistance. However, compared with metal alloy materials, PC material has insufficient hardness and poor wear resistance compared to metal materials, which makes it easier to be scratched by metal materials.

Nylon, also called polyamide, is a tough angular translucent or milky white crystalline resin. Nylon has good electrical insulation, very strong mechanical strength, and excellent high temperature resistance. The nylon material is resistant to abrasion, has good flame retardancy, is non-toxic and has no odor, and has good shock absorption and sound attenuation. In addition, , Nylon is chemically stable, resistant to weak acids, alkalis and general solvents. However, nylon has poor dyeability and high water absorption, which affects the dimensional stability and electrical properties of the switch socket.

Therefore, relatively speaking, high-quality household wall switch socket usually use PC materials, because of their excellent performance and affordable prices, and their service life is very long.
