Wall sockets are necessary equipment to control and continue household appliances, so it is especially important when buying sockets. However, there are many brands and types of sockets on the market. Many consumers do not know how to choose. Which one is more suitable for home decoration? The following editors will teach you how to buy wall sockets and teach you how to identify sockets. Bad.
How to buy wall socket
1. When choosing a wall socket, first of all, we can look at its structure. Most of the sockets on the market today are large panel styles, which have a better feel and appearance than the previous thumb style. The biggest problem with the thumb-type sockets in the past is that it is easier to get stuck, the torque is shorter, and the spring is lighter than Microsoft or a little too hard, which may cause the switch to get stuck. Large panel sockets do not have these problems. From the structure of the socket, we can identify its quality.
2. When choosing a wall socket, we can also look at its contacts. In general, the larger the contacts of conductive parts in the switching process, the better. Looking at its material, the types of contacts are now divided into three types: silver-cadmium alloy, silver-nickel alloy and pure silver. The cadmium element of the silver-cadmium alloy touch is a heavy metal, which is harmful to the human body, and its fusion with silver is not very good. It will form small particles of cadmium metal on the surface of the contact, and may draw an arc when conducting electricity. Silver-nickel alloy is the ideal contact material at present, it has better hardness, good conductivity, and is not easy to oxidize and rust. The contact performance of sterling silver is good, but the texture of sterling silver is soft and easy to oxidize, so its contact will be easily deformed and melted. It can also be identified from the contacts of the socket.
3. When choosing a wall outlet, we can also look at its materials. Nowadays, switch sockets on the market generally use PC materials, which are resistant to high temperature and impact, and are not easily discolored. On the base of some inferior sockets, black nylon material is used to replace PC material, which reduces the cost. The PC materials used by many manufacturers are produced domestically, and the impurities are relatively high, and the heat resistance is not very good. And in order to save costs, some manufacturers may not use PC materials for the front panel of their sockets, but use ABS or hybrid materials instead. These socket materials are easily discolored, and they have poor heat resistance, poor impact resistance, and a rough surface.
Summary of the article: How to buy a wall socket ? From the above, we can know that we can identify the quality of the socket from the structure, contacts, materials, etc. of the socket, so that we can correctly choose the appropriate home decoration socket. However, when wiring the wall switch, it is necessary to distinguish between the live wire, the neutral wire and the ground wire, so that the short circuit phenomenon will not occur when the switch socket is installed.
