How to choose home improvement switch socket
First, look 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 smooth and textured in surface. The panel materials are all PC materials (bullet-proof glue) imported from American General Company, which have excellent flame retardancy, insulation and impact resistance, stable materials and are not easy to change color. Switches and sockets made of this material can greatly reduce the occurrence of fires caused by circuit reasons.
Secondly, look at the internal structure
As far as switches are concerned, pure silver contacts and conductive strips made of silver-copper composite materials should usually be used to prevent oxidation caused by arc when opening and closing. The conductive bridge of high-quality panel is made of silver-nickel-copper composite material. Silver material has excellent conductivity, while silver-nickel alloy has very strong ability to suppress arc. The switch adopts brass screws for wire pressing, with large and good contact surface, strong wire pressing ability and stable and reliable wiring. Single-hole connection copper column has large connection capacity and is not limited by wire diameter.
Third, safety.
The safety door of the socket is essential. When choosing sockets, try to choose products with doors. Secondly, check the fastening degree of the socket clip, and the smooth insertion force is a key factor. At the same time, strong extrusion makes the plug difficult to fall off, effectively reducing the occurrence of non-human power outages. At the same time, the socket clip is made of high-quality tin-phosphorus bronze, which has good conductivity and strong fatigue resistance, and ensures that the socket times are 10000 times (5000 times according to the national standard).
