< ;p style="text-indent: 2em; text-align: left;">    As a bridge between power supply and electrical appliances, sockets are related to the family Daily "big safety", then how to choose a switch socket? In fact, there is a lot of information here. The main difference between sockets lies in the materials used, the internal structure and the appearance design. Inexpensive products usually compromise on materials, touch and durability.

　　一、material

　　A good socket will use PC materials. When selecting, it is best to perform a combustion test on its core components. PC materials have the characteristics of moisture resistance, heat resistance, flame retardancy, and high impact resistance, and have very good resistance to ultraviolet rays. Will change color.

　　二、Appearance

　　The surface of a good quality socket should be flat, smooth, round, with fine material, good color, ceramic white, no black spots, shrinkage, air lines, burrs and other problems.

　　Three, feel

　　You can take a look at the weight, usually use good shell insulation materials, high-quality contacts, and current-carrying copper sheets. A good socket spring is moderately hard and flexible, and has a strong opening and closing transition. The touch feel is light and not tight. Good switches generally have harder springs and have a strong sense of force when switching, while poor switches are very soft. If they are too soft, they may be m& of ABS material, and the switch handle often stops. The phenomenon in the middle position.

　　 Fourth, internal structure

　　 For sockets, the first thing to consider is its safety. The safety protection door of the socket is indispensable, you should try to choose the product with the protection door when choosing the socket. Secondly, check the tightness of the socket clips. Smooth insertion force is a key factor. The plug insertion and removal should require a certain amount of force and cannot be inserted with one foot. This effectively reduces the occurrence of power outages caused by non-human factors. At the same time, the socket clip is m& of high-quality tin-phosphorus bronze, which has good electrical conductivity and strong fatigue resistance, ensuring that the socket is plugged and unplugged up to 10,000 times (the national standard is 5,000 times).

　　5. Safety certification

　　 Qualified switches and sockets are compulsory certification products stipulated by China Quality Certification Center. Please confirm the 3C mark and the implementation national standard number on the product when purchasing. Each switch socket base is engraved There are tr&marks, certificates of conformity, and 3C certification marks.

　　Combining these aspects, we are more targeted when choosing switches, but we should also pay attention The markings on the base of the switch and socket and the rated current and voltage. In this way, we can get the high-quality products we need.
