1. Look at the appearance

the style and grade of the switch should be consistent with the overall indoor style. In addition, white switches are the mainstream, and the overall tone of decoration in most rooms is light, so dark switches such as black and Brown should not be selected

2. by hand

switches with good quality are mostly made of high-grade materials such as bulletproof glue, which have high fire resistance, moisture resistance, impact resistance, etc., and the surface is smooth. When purchasing, you should consider your hand feeling, preliminarily determine the material of the switch based on the hand feeling, and ask the dealer. Generally speaking, the performance of products that have a thin and brittle feel with a non smooth surface is not reliable. The panel of a good switch socket shall be free of bubbles, scratches and stains. The handle of the switch is light but not tight. The jack of the socket needs to be equipped with a protective door, and the plug plug should be plugged in and out with a certain force, and one pin cannot be plugged in

3. Weigh the weight

when buying a switch, you should also weigh the weight of a single switch. Because the weight of a single switch is heavy only when the copper sheet in the switch is thick, and the copper sheet in the switch is the most critical part of the switch. If it is alloy or thin copper sheet, it will not have the same weight and quality

it is best to choose well-known brands. Because the quality of the switch is related to the normal use of electrical appliances, and even the convenience of life. The switches and sockets produced by many small manufacturers are sometimes very unreliable, which won't take long at all, and it's obviously very troublesome to replace them often; However, most well-known brands will make effective commitments to consumers, such as “ Guaranteed service life of 12 years &rdquo& ldquo; It can be switched continuously for 10000 times ” Etc

5. Choose services

try to buy at the exclusive store or sales point designated by the regular manufacturer, and keep the shopping voucher, so as to ensure that you can enjoy the after-sales service in the future

6. marked

pay attention to the marks on the base of switches and sockets: such as national compulsory product certification (CCC), rated current and voltage value; Production model, date, etc

7. Whole package

the product is packaged completely, and there should be a clear address and telephone number of the manufacturer on it, with instructions and certificate of conformity inside
