The purchase of switch socket is very important, because the use of wall switch socket directly affects the safety of our life. The reason why the plug can not be inserted into the socket during daily use is because the temperature of the live parts is likely to cause serious deformation of the outer casing. The switch socket cannot be operated, and some even cause the live parts in the jack to contact each other, forming a short circuit and causing a fire.
When we buy switch sockets, Siemens reminds you that you should start from the following aspects:
A. Inspection: complete packaging, complete information, exquisite design Product packaging should be standardized and complete, design and printing beautiful, the above should have clear trademark, manufacturer address, telephone, company website and other information, there are instructions for use and certificate, attachment screws Wait, whether all switches have genuine credentials, such as anti-counterfeiting labels.
B. Outlet appearance: The surface is smooth and smooth, no bubbles, no scratches, no smudging, uniform color and texture. The good socket has strong material stability, is not easy to corrode and discolor, and the appearance surface is smooth and smooth, no bubbles, no scratches, no stains, uniform color and texture, and the naked eye can clearly see that the hand feel is very good. The inferior surface is not smooth, there are many burrs on the side, the touch button is light and the sound is crisp, the socket of the socket needs to be equipped with a protective door, and the plug does not need much force;
C. Test the tightness of the switch socket: the socket should be plugged and unplugged smoothly, preferably with a protective door; there will be no sound inside when shaking
In the use of the switch socket, it is found that the socket temperature is too high or there is a slamming fire, the plug and the socket are in poor contact, and when the plug is too loose or too tight, it should be stopped and replaced in time.
E. Component: The switch of the copper piece is relatively heavy. After the product is delivered, a good switch socket should have sufficient weight. The copper piece inside the switch is the most critical part. If it is alloy or thin copper, it will not have the same weight and quality. Products with a very light weight must be suspected of cutting corners and should be cautious when purchasing.
F. Accessories: The base of the cold-rolled steel plate is more durable, and the copper-plated screws are more conductive. The switch socket must be screwed to the base of the wall. The solidity of the brand base will also affect the use of the switch panel. Some brands now use the cold-rolled steel plate to make the base, which will be more durable. In addition, there are screws with fixed wire ends on the back of the switch socket. The good ones should be pure copper. The conductive extension is good, and it is relatively large. The screws of some switch sockets are copper-plated or small, which indicates the quality. Not very good.
High-quality switch socket structure features:
High-quality switch sockets have outstanding performance in terms of materials, design and safety. Midea Matsushita Electric Co., Ltd. specializes in the production (supply) sales of switch socket products. The company has a good market reputation, professional sales and technical service team, with years of experience in operating switch sockets, has won the praise of domestic and foreign manufacturers. This article introduces the structural characteristics of our company's switch socket products:
A. Tin-phosphorus bronze is used for plugging and fastening: the copper plate of the socket is made of tin-phosphorus bronze material, which has high strength, good plasticity, good electrical conductivity and is not easy to be deformed;
B. Anti-electric shock protection door design ensures safe use: the power sockets are equipped with protective doors to prevent children from getting electric shock;
C. Add lightning protection function to protect life safety: add lightning protection module and one more layer of protection to effectively reduce the damage caused by lightning and overvoltage to people and property (this is not available in many similar products);
D. Unique structural design, accurate insertion and removal: cylindrical plugs and flat plugs have special insert sleeves to ensure the stability of current.
E, the preparation icon and the label card are convenient to use: the icon of the information socket and the label card can easily identify the socket use and circuit, which is convenient for use and inspection;
F. Remote design, reduce the use of mutual interference: the distance between the second and third holes can reach 42MM, and two large plugs can be inserted at the same time to improve the efficiency of use.
