The wall switch is an item that we use every day in our lives, but you may not know its model. Let's introduce the model of the wall switch and how to buy the wall switch.
There are four types of wall switches: 86 types, 120 types, 118 types, and 146 types. Type 86 refers to a switch socket product with a length of 86mm and a width of 86mm. Type 120 refers to a switch socket product with a length of 120mm and a width of 78mm. Type 118 refers to a switch socket product with a length of 118mm and a width of 78mm. A switch socket product with a width of 78mm.
The panels of high-quality switch sockets should be made of high-grade plastic products with uniform material and smooth surfaces. The panel material is made of high-grade PC material, which has excellent flame retardancy, insulation, and impact resistance, and the material is stable and not easy to change color.
Switches generally use sterling silver contacts and conductive sheets made of silver-copper composite materials to prevent oxidation caused by arcs when opening and closing. The conductive bridge of the high-quality panel is made of silver-nickel-copper composite material, which has excellent electrical conductivity, while the silver-nickel alloy has a strong arc suppression ability. The switch is crimped with brass screws, the contact surface is large and good, the crimping ability is strong, and the wiring is stable and reliable.
Check the tightness of the wall switch or socket clip, stable insertion force is a key factor. At the same time, the strong extrusion makes the plug not easy to fall off, effectively reducing the occurrence of power outages caused by non-human factors. In addition to considering safety, the appearance design of switch sockets has also attracted more and more consumers' attention. The color selection is as close to the wall color as possible.
