there are various types of switches and sockets in the market, and their quality varies. Consumers do not know what to do when shopping. Switches are related to the safety of home, so the quality of switches is very important. Experts teach you to distinguish the quality of the switch from seven aspects and correctly choose the switch with high quality

at present, the variety of switches and sockets in the market is diverse, with mixed good and bad, which makes consumers at a loss when purchasing. Switches are not only a kind of household functional products, but also the main components for safe electricity use. Their product quality, performance and materials play a crucial and decisive role in preventing fire disasters and reducing losses

appearance: generally good products have flat appearance, no burr, bright color and its material is high-quality abs+pc material, with good flame retardant performance and non fragile. Although the surface of some products is bright and clean, it seems to be coated with a layer of oil, but the color is pale and the texture is coarse. This kind of material has poor flame retardancy. You can light it with fire to try its flame retardancy. If it burns out quickly, it is good plastic, otherwise it is poor plastic

press by hand: a good product panel will not be taken down directly by hand, but must use some special tools, while general non mainstream medium and low-end products are easy to take off the lower cover by hand, causing indecency in homes and public places. When selecting, use your index finger and thumb to press the cover diagonally to form an end point, one end is pressed and held still, and the other end is pressed hard. The product with loose and sunken cover is of poor quality, otherwise the quality is reliable

ear listening: gently press the switch function part, the lighter the sliding plate sound, the smoother the hand feel, and the stronger the sense of rhythm, the better the quality; On the contrary, when opening and closing, the sound is impure, dynamic and astringent, and the sound with intermittent state is of poor quality

look at the structure: at present, there are two general switch structures: sliding plate type and swing rod type. The sound of skateboard switch is strong, and the feel is elegant and comfortable; The swing bar type has a crisp sound and a little metal impact sound. It is more stable than the traditional sliding plate type structure in arc elimination and service life, and the technology is mature. 2. Double hole pressing plate wiring is safer than screw pressing. Because the former increases the contact area between wires and electrical parts, it is oxidation resistant and not easy to loose, poor contact and other obstacles; The latter screw is easy to crush the wire when it is firm, and the contact area is small, which makes the electrical parts easy to oxidize and age, resulting in poor contact

material selection: switch pure silver has strong conductivity, low calorific value and high safety performance. If the contact is made of copper, its performance will be greatly reduced; Using Tin Phosphorus raw copper sheet as socket material can get the best strength, toughness, elasticity and other indicators, which is dozens of times more durable than the socket with general brass as reed, and there is rarely the phenomenon of strong arc burning the socket when inserting the board; The gold-plated reed needle is extremely difficult to oxidize and has stable performance, which can ensure clear and true sound quality and fast and accurate data transmission

look at the sign: what is the maximum power? At present, the rated current of household general switches commonly used in the market is 10a, the socket current is 10A or above, and the larger socket of air conditioners and water heaters is 16A. Good products clearly identify the available current intensity, while the identification of inferior products is vague, and the data is exaggerated, so it is impossible to determine whether the rated current of the identification can pass safely without worrying and not full of smoke

brand recognition: famous brand products have been tested by time and market. They are recognized as safe products in the eyes of consumers. Both materials and quality are strictly controlled. There are high-quality processes in all aspects of packaging, transportation, display and image design. Famous brand electrical products are not only safety electrical functional products, but also exquisite and elegant works of art that reflect elegant cultural taste

nowadays is an era of pursuing fashion. Although electrical appliances are not a kind of consumer goods for the general public, like mobile phones, exquisite styles, designs with different styles, and creative ideas are all for a safer and more comfortable life

in fact, no matter from which aspect, families should choose some famous and high-quality products
