How to identify the high-quality toggle switch and DC power socket, the method is very simple, the detailed method will be introduced to you below, please understand in detail.
1. Look at the appearance. The panel of high-quality switch and socket is made of high-grade plastic products, which looks even and smooth. For example, the electronic plastic panel materials are all PC materials (bulletproof glue) imported from general motors of the United States. Their flame retardancy, insulation and impact resistance are excellent, and the materials are stable and not easy to change color. Selecting such materials to produce the switch and socket can greatly reduce the technical life of the fire caused by the original field of Tian circuit.
2. Open the switch panel, and you can see the internal structure of the switch and socket. As far as the switch is concerned, the pure silver contact is usually made of the conductive sheet made of the silver copper composite material, so as to prevent the oxidation caused by the arc during the opening and closing. The conductive bridge of high quality and plate is made of silver nickel copper composite. The conductivity of silver material is excellent, and the ability of silver nickel gold to restrain arc is very strong, so that the switch can be closed more than 80000 times, far exceeding the international standard of 40000 times. The electronic switch adopts brass screw to press the wire, the contact surface is big and good, the wire pressing ability is strong, the wiring is stable and reliable. Single hole connection copper post, large connection capacity, not limited by wire diameter thickness. In addition, 6-8 (upper, lower, left, right and four corners) fixed installation holes are reserved for the product panel, which is free and flexible, and suitable for various installation needs.
Third, for ten DC power sockets, the first thing to consider is its safety. The safety protection door of the socket is essential. When choosing the socket, you should try to choose the product with the protection door. Secondly, check the tight response of the socket clamp, and the stable insertion force is a key factor. The structure of the clip of the electronic socket breaks through the traditional design, adopts the strong extrusion method, greatly enhances the cooperation between the clip and the plug, avoids the worry of heating when using for a long time, at the same time, the strong extrusion makes the plug not easy to fall off, effectively reduces the occurrence of the non-human factor power-off accident. At the same time, the clip of DC power supply plug-in leek is made of high-quality tin phosphor bronze, which has good conductivity and strong fatigue resistance, and ensures that the plug-in times of socket are 10000 times (5000 times according to the national standard).
