Although the switch socket is small, it is an indispensable part of every family. There are also a few electrical faults and fire accidents caused by switch sockets every year. Whether the switch socket is safe or not, this has a lot to do with the way the internal wires are connected. Therefore, you must purchase high-quality and safe brand switch sockets when you purchase. At present, the most advanced connection method for switch socket installation is the quick connection terminal structure. This type of structure connection is simple, only the wire is inserted into the terminal part, the connection is completed, but the wiring state is even and firm and firm, even if a bowling ball is hoisted, the connection will not fall off. The live part is not exposed, so there is no danger of electric shock during construction.
In the face of the majority of people in the purchase of switch sockets, and the variety of good and bad switch sockets in the market, now the switch socket purchase secrets are now brought to everyone, so that everyone can bring safe and reliable high-quality switch sockets home.
Simply put, the switch socket has a choice of "six points", one looks at the logo, two looks at the appearance, three looks at the design, four looks at the insulating material, five looks at the conductive parts, and six smells.
A look at the logo. When purchasing, please pay attention to the mark on the base of the switch socket: whether there are 3C certification, rated current size, trademark and other signs, observe whether there is a clear manufacturer address phone on the product packaging box, whether there is a manual and certificate in the package. Bull expert reminder: the general switch rated current is 10A, when using some high-power appliances, you should try to choose a switch with a large rated current (such as rated current is 16A), in order to avoid the instantaneous high current burned when the switch is energized.
Second, look at the appearance and feel of the switch socket. The appearance should be smooth and flat, uniform in color, and have a certain hardness and weight. At the time of purchase, you can try to gently switch the switch. The quality product feels crisp and smooth, while the inferior product switch feels very soft or has obvious obstruction, and even the phenomenon that the switch is stuck in the middle position often occurs.
Look at the insulation material. Insulation is very important for the safety performance of switch sockets. From the appearance point of view, the good material has no bubbles, the texture is hard, it is difficult to scratch, the structure is strict after molding, and the weight is heavy. Some inferior products on the market use PC reprocessing, the impurity content is high, and the heat resistance is not. Better, and even worse, replace PC materials with mix or ABS. The product not only has excellent impact resistance and poor heat resistance, but also looks very rough and discolored.
Four look at the design. Incorporating a scientifically designed design, it is safer and more secure to use, and is humanized in the details. For example, the Bull Switch socket has super triple lightning protection technology and modular lightning protection components to completely block lightning hazards and ensure safe and worry-free electrical appliances!
Five smells of the product. The high-grade switch socket cover and frame are made of high quality imported PC material, non-toxic and no obvious smell. The back seat adopts imported odorless PA66 nylon material, and the product has no obvious plastic smell. Inferior switch socket products use more materials, ABS, nylon, PVC and other recycled mixed materials, not only have obvious plastic odor, and are easy to change color and yellow.
Six look at the internal conductive parts. Since some components of the switch socket are installed inside the wall, the copper piece is easily rusted and rusted, and the resistance becomes large after rusting, and it is easy to generate heat when working. If the heat accumulates too much, the fire may cause a fire hazard. The bull switch socket adopts tin-phosphorus bronze material with excellent conductivity and is treated by surface refining nickel plating process. It resists oxidation and prevents copper rust, generates less heat and has superior electrical conductivity, and its service life can reach more than 80,000 times.
Mastering the above six points, it is no longer difficult to purchase safe and high quality switch sockets. Wanguan hardware machine grid also reminds that consumers should not be cheap when buying and selling switch sockets. Safety and durability are the core of switch socket selection.
