Universal switch
1. Look at the appearance: The style and color of the switch should match the overall style of the room. For example, if the overall color of the interior decoration is light, then black, brown, and other dark switches should not be used.
2, to see the feel: good quality switches are mostly made of ballistic rubber and other advanced materials, fire performance, moisture resistance, anti-impact performance, etc. are higher, the surface is smooth, when buying should consider their own feel up touch, with the handle initially Determine the material of the switch and ask the dealer. In general, products whose surface is not smooth and which have a thin, brittle feel are 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, look at the weight: buy switches should also weigh the weight of a single switch. Because only the copper thickness inside the switch, the weight of a single switch will be large, and the inside of the copper is the most critical part of the switch, if the alloy or thin copper will not have the same weight and quality.
4, look at the brand: to encourage everyone 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 dealers in the interview have expressed the same view, that is, many of the switches or sockets produced by small factories in Guangdong and Wenzhou are not reliable, and they simply cannot be used for a long time, and frequent replacement is obviously very troublesome; but most of the well-known brands Will make effective commitments to consumers, such as "available 15 years", "guarantee 12 years of service life", "can be continuously switched 10000 times" and so on.
5, look at services: as far as possible to the regular manufacturers designated stores or point of sale to buy, and ask for a shopping invoice, so as to ensure that you can enjoy future service.
6, see the logo: to pay attention to the switch, socket on the base of the logo: including the Great Wall Certification (CCEE), rated current and voltage.
7. Look at the packaging: There should be a clear manufacturer's address phone number on the packaging surface, with instructions and certificates.
