At present, there are many kinds of switch sockets on the market, which make the consumers feel at a loss when purchasing. The switch socket is not only a home decoration function, but also the main component of safe electricity. Its product quality and performance materials are used to prevent fire. Reducing losses has a crucial and decisive role. Chint Electric has summed up a small set of experience in arguing serious and superior and inferior electrical products for consumers to refer to when selecting electrical products.
1. eye view
In addition to good appearance, the good product has a smooth surface, no burrs, burrs, and uniform color. The materials are mostly imported high-quality PC materials, and the flame retardant performance is good. Some products have a smooth surface and seem to be coated with a layer of oil, but the color is pale and the texture is coarse. The flame retardancy of such materials is not good, which will cause fire hazards for household electricity. Zhengtai electrical products use German high quality Bayer plastic parts, high strength, high temperature resistance, no fading, no pollution.
Generally speaking, a good product panel is difficult to remove directly by hand, and must rely on certain special tools, while the general non-mainstream middle and low-end products are easy to take the cover under the hand, resulting in indecent home and public places. When the switch is selected, the index finger and the thumb are respectively arranged at the opposite ends of the face cover, and the end is pressed and held at the other end, and the other end is pressed hard. The product of the cover is loose and the product is poor, and the quality is credible. The advanced on-off structure and special shock absorbing device ensure that Chint’s electrical products have excellent hand feeling and humanized design, which makes you feel comfortable.
The finger pressure switch function has no empty stroke, the sound is crisp, the hand feels smoother, and the rhythm is stronger, the quality is better; on the contrary, the sound is impure, the motion is sluggish, and the sound in the middle intermittent state is of poor quality. Through excellent structural design and high-quality material selection, Zhengtai Electric has excellent audio-visual effects during use.
4, see the structure
At present, there are two types of switch structures: the seesaw type and the swing type. The seesaw type switch has strong sound and elegant and comfortable feeling. The swinging sound is crisp, with a slight metal impact sound, light hand feeling and flexible function conversion. B. The main wiring methods of the switch products are pressure plate wiring, screwless wiring, terminal wiring, and saddle terminals. The pressure plate connection increases the contact area between the wire and the electrical device, resists oxidation, is not prone to looseness, poor contact, etc.; and the threadless connection is easy to crush the wire, the contact area is small, the electrical component is easy to be oxidized and aged, resulting in poor contact; Most of the products use terminal block wiring.
5, than the selection of materials
The use of silver cadmium oxide as the switch contact has strong conductivity, low heat generation and high safety performance. Relatively speaking, the performance of copper material is greatly reduced; the socket material can achieve strength, toughness and elasticity by using tin phosphor bronze sheet. High performance, ten times more durable than brass reed products, greatly reducing the phenomenon of strong arc burnout during use; data socket with gold-plated spring needle, anti-oxidation, stable performance, can guarantee sound quality Clear and true and fast and accurate data transmission. Zhengtai Electric uses silver cadmium oxide as the contact material, the contact area is more than 12 square millimeters, and the thickness is more than 0.4 mm. It has good electrical conductivity, oxidation resistance, low temperature rise, low arc and environmental protection performance, ensuring the best use of products. .
6, look at the logo
At present, the rated current of the household general switch used in the market is 16A, the outlet current is 10A, and the socket of the air conditioner and the water heater is 16A. The good product clearly identifies the available current intensity, while the inferior product has a blurred logo and the data is exaggerated. Determine if the rated current of the mark can pass safely and without passing through the house. Each product of Zhengtai Electric has national mandatory CCC certification, rated current and voltage value and product model. In addition, the product packaging has clear site and contact information. The package contains instructions for use and inspection certificate to ensure your safety. use.
7, recognize the brand
Brand-name products have been rigorously tested by time and market. They are recognized as safety products in the minds of consumers. Both materials and quality are strictly controlled. Packaging, transportation, display and image design all have high-quality processes. Famous brand electric products are not only A safety electrician functional item is a piece of art that is exquisite and elegant, reflecting the taste of elegant culture. Zhengtai Electric took the lead in launching OPT (Seiko Switching Standard), and firmly grasped the four stages of “design, material selection, manufacturing and testing”, aiming to create high-quality switch products with “quality consistent” for consumers. In recent years, Zhengtai Electric has successively won the honors of “China Electrician Industry Association Recommended Products”, “National Residential Industrial Base” and “National Laboratory”. At present, “China Famous Brand” is also in the final stage. Through years of careful cultivation and steady development, Zhengtai Electric has become one of the preferred brands of consumers in the forefront of domestic electricians.
Nowadays, it is an era of fashion pursuit. Although electrical appliances are not a kind of popular consumer goods, they are just like mobile phones. The exquisite styles and styles are different, and the original creativity is to create a safer and more comfortable warmth. life. Overall, to buy a good performance switch, socket products, should be preferred top brand, brand-name products are not only high quality, fashionable, diverse specifications, more importantly, to ensure safe and reliable use. I hope that you can choose the right electrician products in the decoration of the warm home.
