How to choose switches and sockets
In the house decoration, those large furniture decorations are the main points of our inspection, but in addition, other relatively small parts cannot be ignored. In addition to the inspection of wires and pipes, the switch must also be paid attention to, in order to make our Life is more convenient and safer. Switch selection is very important. What kind of switch is good?

How to select switches—the key points of selecting switches
Looking at the appearance, the panels of high-quality switches and sockets should be made of high-grade plastic products, which look uniform in material and have a smooth and textured surface. The panel materials are made of PC material (bullet-proof glue) imported from General Motors. Its flame retardancy, insulation and impact resistance are excellent, and the material is stable and not easy to change color. Switches and sockets made of such materials can greatly reduce the occurrence of fires caused by electrical circuits.
Looking at the internal structure, as far as the switch is concerned, pure silver contacts and conductive sheets made of silver-copper composite materials should usually be used to prevent the arc from oxidizing during opening and closing. The conductive bridge of the high-quality panel is made of silver-nickel-copper composite material. The silver material has excellent electrical conductivity, and the silver-nickel alloy has a very strong arc suppression ability. The switch uses brass screws to press the wire, the contact surface is large and good, the wire pressure is strong, and the wiring is stable and reliable. The single-hole wiring copper post has a large wiring capacity and is not limited by the diameter of the wire.

Safety, the safety protection door of the socket is indispensable, you should try to choose the product with the protection door when choosing the socket. Secondly, check the tightness of the socket clip. Smooth insertion force is a key factor. At the same time, the strong squeeze makes the plug not easy to fall off, effectively reducing the occurrence of power failure accidents caused by non-human factors. At the same time, the socket clip is made of high-quality tin-phosphorus bronze, which has good electrical conductivity and strong fatigue resistance, and guarantees the socket plug-in times of 10,000 times (the national standard is 5000 times).
After selecting the switch, you need to install it. Before installing, make sure whether the power is cut off. Do not install the switch when the power is not cut off. This is very easy to get an electric shock and accidents. Don’t do it after installation. Turn on the power in a hurry, first check to determine whether it is completed and whether there are omissions or errors.
