How to distinguish high-quality switch and DC power socket, the method is very simple, detailed methods will be introduced to you below, please understand in detail.

First, look at the appearance. High-quality switch and socket panels are made of high-grade plastic products, which look uniform in material and smooth in appearance and texture. For example, Pinzan Electronics imports PC material (bullet-proof glue) from General Corporation of the United States. Its flame retardancy, insulation and impact resistance are excellent, and the material is stable and not easy to discolor. Choosing such material to produce gates and sockets can greatly reduce the number of technicians involved in the fire caused by the field circuit.

2. Open the panel of the switch, and you can see the internal structure of the switch and socket. As far as switching is concerned, pure silver contacts are usually made of conductive sheets made of silver-copper composite materials, which can prevent oxidation caused by arc during opening and closing. Silver-nickel-copper composite material is used for conductive bridge with high quality and slab. The conductivity of silver judgement is excellent, and the ability of silver, nickel and gold to restrain arc is very strong, which ensures that Praise switch can be turned off more than 80,000 times, far exceeding the international standard of 40,000 times. Pinzan electronic switch adopts brass screw wire pressing, large and good contact surface, strong wire pressing ability, stable and reliable wiring. Copper pillar with single hole connection has large connection capacity and is not limited by wire diameter. In addition, the product panel reserved 6-8 (upper and lower left and four corners) fixed installation holes, free and flexible, suitable for a variety of installation needs.

Third, for 10 DC power sockets, the first consideration is its security. Safety door of socket is indispensable. When you select socket, you try to choose the product with protection door. Secondly, to check the tightness of the socket clamp, the stability of the insertion force is a key factor. The structure of Pinzan electronic socket clamp breaks through the traditional design. The use of strong extrusion greatly enhances the cooperation between the clamp and plug, eliminates the worry of heating when used for a long time. At the same time, the strong extrusion makes the plug not easy to fall off and effectively reduces the occurrence of non-human factors of power failure. At the same time, DC power socket clamp is made of high-quality tin-phosphorus bronze, which has good conductivity and fatigue resistance. It ensures that the number of sockets is selected 10,000 times (national standard is 5,000 times).
