Switch socket is very important building material, if you ignore, then there will be many problems in the future home life, but many friends even if it is important to switch socket, but when buying it is confused, do not know how to judge the good and bad, today small Edited for everyone to talk about, how to judge the quality of the switch socket!
First, look at the material to see the material
The copper in the wall switch socket is equivalent to their heart, and also determines its service life. Most of the common wall switch sockets use bare copper parts, but they are not wear-resistant and easy to rust. If they are used for a long time, the conductive and heat-conducting properties will be degraded. This will result in a long service life and prolonged burnout problems. There are security risks.
Second, the lightning protection function of the switch socket
Line aging, quality problems, etc., if it is easy to cause safety problems in thunderstorms, lightning protection technology can block the high voltage, high current and ultra-high temperature caused by lightning, more reassuring. Therefore, when selecting switch sockets, be sure to pay attention to the following lightning protection functions!
Third, look at the contact size and material
Contact points of conductive parts during switching. The first one depends on the size (the bigger the better), the second depends on the material. The main contact is silver alloy and pure silver. Silver alloy is the most ideal contact material at present, and its electrical conductivity and hardness are relatively good and it is not easy to oxidize and rust. In fact, pure silver is not suitable for the contacts, and the conductive properties are indeed good, but the pure silver texture is relatively soft and easily oxidized (such as silver jewelry will turn black after a long time). The texture is soft, and the contacts on the switch are deformed; if the oxidation is rusted, the conductive properties will be much poorer, and the rust spots will also easily generate heat. It is easy to burn the contacts.
Fourth, the best thickness of the power cord can access
Loosening of the power cord of the wall switch socket will hurt the life and use of the appliance, and even cause dangerous accidents. The power cords with different thicknesses can be connected to avoid the risk of loosening.
