Currently, the market variety of home wall socket switch, good and bad, to consumers to buy a certain degree of difficulty. The switch socket is not only a home decoration supplies, but also the main components of safe electricity. What to buy wall switch socket precautions?
Material
PC material is recognized as the industry's best switch panel material, it flame retardant, insulation, high temperature resistance, impact resistance and so on compared to the past, nylon 66 and other materials have outstanding performance. Practice has proved that the use of PC material switch panel products in a variety of harsh environments can be used normally, not easy to yellow, no discoloration, anti-aging ability. However, due to the price of PC material relative to other materials is a big leap, but also makes the switch panel manufacturers, and even some brands will choose to use other materials, such as electric jade powder, nylon 66 instead of PC material, Or just choose the PC material on the panel, the use of nylon material on the base. In addition, some manufacturers have now broken through the old concept of the switch panel, using maple, alloy and other materials as the switch panel material, thus providing consumers with more and more choices.
Appearance
For consumers, the appearance of the product can often reflect its quality from one side. Surface smooth and smooth, uniform color, texture, generally better quality products. In addition, consumers should also choose the brand identity on the panel clear, full, there is no surface burr on the product.
3. Internal structure
In the past, the switch usually used silver or silver-cadmium alloy as the contact material, but the pure silver, silver-cadmium alloy is easy to cause pollution, are not the best material to do the contact. Better switch with tin phosphor bronze, good strength, high hardness, good elasticity, corrosion resistance, abrasion resistance, small resistance, good conductivity, to extend the service life.
4 feel
Consumers try to press the switch in the store, it should be noted: high-quality soft and hard spring switch moderate, excellent flexibility, opening and closing of the transition more strength. Some poor quality switch in use after a period of time, the switch button may appear in a middle position, thus laying a serious fire hazard. Consumers can 掂 掂 a switch, high-quality switch products often because of heavy use of copper and silver and other metals, will not have the same feel as some of the inferior products floating.
5. Humanized design
Now, most well-known brands have night lights on the switch panel, some using the most traditional fluorescent paint night indication, and some are powered by the way the light. In the power of light, it is divided into two kinds of LED lights and neon lights. Compared with the traditional way of fluorescent coating, the way of power supply is undoubtedly more environmentally friendly, and can provide consumers with softer and more comfortable light.
6. Packaging and instructions
Brand open-panel products are usually very focused on consumer satisfaction, so the packaging and brochures of their products more sophisticated than the no-name products, detailed, in addition to indicate the product name, brand, but also indicate the product's technical indicators , Installation and safety precautions, after-sales service and other related matters.
7. Safety certification
China's switch products for mandatory safety certification (CCC certification) requirements. Qualified switch products must have been certified by the state and in line with international industry standards. Domestic brands usually pass 3C certification, ISO9000 series certification, and some international brands in addition to the 3C certification, may also get other national and international safety certification. These related certifications are usually marked on the product itself, in the package, or in the instructions, with some of the more obvious signs. In order to ensure the safety during use, consumers should also choose those who have passed the relevant certification of the product.
