Right now is the peak season decoration, the owners focus on the choice of high-quality wire, electrical appliances, the quality of the switch panel should also pay more attention. Although they are very small home improvement role, but directly related to the service life of electrical appliances, but also relates to electricity safety. In the purchase of the switch panel, in addition to pay attention to the material, the safest way is to check whether the product has passed 3C and other compulsory certification.
Low-quality products stored electricity hidden <br> switch panel, the outlet looks very simple structure, and only the terminal equipment, so most consumers do not pay attention, but in fact, low-quality switch may cause a sudden fire. For the switch, if the structure or raw material is not good, directly affect the life of the switch panel.
If the switch panel used in copper with more impurities, thin copper thickness, poor conductivity, high switching temperature, there will be the possibility of switching ignition. Bad socket may exist virtual connection situation, resulting in a significant increase in energy consumption, the accumulation of a certain period of time after the outbreak, resulting in electrical burned in a short time, or even cause a fire.
Panel yellow hair material is not good <br> In the family life, some consumers will find this phenomenon: the switch panel in use for a period of time after the yellow, and even some switch in the startup or shutdown stopped in the middle, What are these reasons?
Switch panel yellow is due to the factory with substandard materials, a good product is the use of PC material, and some manufacturers for cost considerations, the use of recycled materials PC, plastic properties become brittle, it is easy to yellowing.
Switch panel should pay attention to the material <br> Switch panel how to choose »Experts said that the first view of raw materials, good products will use the PC material. PC material has the characteristics of heat resistance, flame retardancy, high impact resistance, and has very good resistance to ultraviolet light, long-term use will not change color.
PC material can be identified by the following methods: Look at the appearance of high-quality PC material switch surface should be smooth, rounded, delicate material, good color, with ceramic white, black spots, shrink, air pattern, burrs and other issues.
Conductive high-quality switch should be high-quality brass, silver and silver contacts with nickel-nickel alloy, copper conductive components are used tin phosphor bronze, and copper thickness should reach 0.6mm.
Pay attention to whether the outlet is protected by a door at the time of purchase <br> wall outlet, the best choice for socket with a protective door, that is "safe outlet." It is understood that the protection of the door means that there are two holes in the jack, it is closed when not in use. If the socket with a protective door, plug and unplug a certain degree of intensity and unipolar plug can not be inserted. Plug out, even if the fingers accidentally reached the socket hole will not be electric shock, to prevent electric shock to children.
Choose to look at 3C certification, experts advise consumers to buy well-known brands. These brands have stable stores and distributors, and have the appropriate certificate, service is relatively more secure. Product packaging, high-quality switch products should have a clear factory name, address, telephone, with production date, instructions and certification.
