How to distinguish the quality of wall switch socket
The key to distinguish the quality of wall switch sockets is to look at the application safety and durability of switches and power sockets. Touching the switching power supply is also a very important part. This is called point contact. Regarding the quality of the product, the silver-aluminum alloy contact point is used to maintain the high conductivity of the pure silver. In addition, the strength is much higher than that of the pure silver.
1. Look at well-known brands: Encourage the use of switch socket products with high brand image, and it is very likely to go to specific agents or retail outlets of reliable manufacturers to buy.
2. Look at the logo: pay attention to the logo on the switch base: 3C,CE certification, rated current. You should choose products with certification. In addition, check whether there is a clear manufacturer's detailed address and telephone number on the product packaging box, and whether there is an instruction manual and a certificate of conformity in the packaging. Do not choose goods without guarantee. In addition, when purchasing products with higher rated currents as much as possible, the rated current of the switch products of the general manufacturer is 10AX, and the rated current of the Lanbao switch products is 16AX, and there are more safety precautions.
3. Look at the appearance and touch: the appearance of the product should be smooth and flat, the color should be well-proportioned, with a certain strength and net weight, there is no sound when shaking the power socket, the touch of the switch is light and not tight, and the general switch is very soft of. It often happens that the switch rocker stops at the middle part. It is very prone to common failures of the application. The power socket must be plugged in with a power plug to try to see if it is smooth. Of course, too tight or too loose is not suitable. Lanbao switch products use a unique swing and rocker structure, which is ultra-fast and light to touch.
4. Look at the design plan: The humanized design of the switch socket will make your application more comfortable. For example, does it have lightning protection and can reasonably maintain the safety of high-value household appliances; for example, two and three poles are inserted into the middle interval, if it is too small, it will endanger the second and third power plugs.
5. Look at the insulation layer material: the insulation layer material is very important for the safety factor of the switch socket, but it is difficult for ordinary customers to distinguish. It is naturally best if you can do an ignition test on the key components when purchasing, if there is no standard In terms of appearance, good raw materials generally have no bubbles, are relatively hard, difficult to scratch, and have a tight structure after forming and a heavier weight.
6. Look at the internal materials: the conductive parts of high-quality products should be solved by using high-quality tin-tin bronze electroplating nickel, oxidation resistance and patina, less hot, conductive performance is more extraordinary, and the service life is longer, compared with all copper and tin Tin bronze has better electrical conductivity.
