1. Look at the appearance. The style and grade of the switch should match the overall style of the room. Another white switch is the mainstream, most of the overall color of the interior decoration is light, you should not use black, brown and other dark switches. 2. With your hand. Most of the good quality switches are made of high-grade materials such as ballistic rubber. The fireproof performance, moisture resistance, and impact resistance are all relatively high. The surface is smooth. You should consider the feel of your own touch when you buy, and determine the material of the switch based on the feel of the switch. And ask the dealer. In general, the surface is not very smooth and has a thin, brittle feel. The performance is unreliable. The panel of a good switch socket requires no air bubbles, scratches, or smudges. The touch of the switch is light but not tight, and the socket of the socket needs to be equipped with a protective door. The plug must be plugged and unplugged to a certain degree of force and cannot be inserted on one foot. 3.掂 component. When purchasing a switch, you should also weigh the components of a single switch. Because only the copper in the switch is thick, the weight of a single switch will be heavy, and the copper inside is the most critical part of the switch. If it is alloyed or thin, the copper will not have the same weight and quality. 4. Select the brand. It is best to use well-known brands. Because the quality of the switch is related to the normal use of electrical appliances, and even the convenience of living. Many small manufacturers switch sometimes the outlet is not reliable, it will not take long, and frequent replacement is obviously very troublesome; but most well-known brands will make effective commitment to consumers, such as "guarantee 12 years of service life." , "Can be continuously switched 10000 times" and so on. 5. Choose services. As far as possible to the regular factory designated store or point of sale to buy, and retain shopping vouchers, so as to ensure that you can enjoy future service. 6. There is a logo. Pay attention to the markings on the bases of switches and sockets: such as the National Compulsory Product Certification (CCC), rated current and voltage values, product model, date, and so on. 7. Whole package. The product packaging is complete, there should be a clear factory address phone above, there are instructions and certification.
