The switch controls the opening and closing of all living space lamps in the home. The socket ensures the stable and safe power connection of the household appliances. In a well-decorated home, the use of good switches and sockets can also become the finishing touch in the home environment. However, when selecting switch sockets, the most important thing is to have good safety performance. This is reflected in eight aspects. First, the material. The materials used in the panels of high-quality switches are excellent in flame retardancy, insulation, impact resistance, moisture resistance, etc., and have strong material stability and are not easily discolored. In addition to high-grade plastics, current switchboards also have gold, stainless steel, copper, and other metal materials, providing people with more and more choices.
Second, the appearance. Smooth and smooth surface, uniform color, texture, and generally a good product. In addition, the branding on the panel should be clear and full, with no burrs on the surface. Third, the internal structure. The switch usually uses pure silver contacts and silver-copper composites as conductive bridges, which prevents arc-induced oxidation when the switch is opened and closed. The conductive bridge of the high-quality panel adopts a silver-nickel-copper composite material, and the silver material has excellent electrical conductivity, while the silver-nickel alloy has a very strong ability of suppressing arc, thus ensuring that the switch can be opened and closed more than 80,000 times, far exceeding the international regulations. 40,000 times the standard. Brass screw pressure switch, large contact surface, strong pressure line, stable and reliable wiring. If it is a single-hole wiring copper column, the wiring capacity is large, not limited by the thickness of the wire, it is very convenient. Fourth, feel. Try to switch, a good switch spring moderate hardness, flexibility is excellent, and the opening and closing of the transition is more forceful. There will not be a situation in which the switch button is stopped at a certain position in the middle and it becomes a serious fire hazard. It also allows you to switch on and off. High-quality products use a large amount of copper and silver metal without any feeling of floating. Fifth, the production process. The switch is often touched, especially the color switch panel. If an inferior quality product is selected, it will fade after a long time. If you choose a switch that uses a material that has UV-resistant properties, and you apply a bake-out process to the bezel, the color will not change even if you use it for a long time. Sixth, human design. Nowadays, there are nighttime indicators on a good switch panel, and even the most traditional fluorescent paint night indication method can be developed from a single green fluorescence to multiple colors. Power light is another way of indicating the night. At present, LED lights are used to replace the fluorescent light to ensure longer life, lower heat rate, and softer light. Some switches use grid structure panels and thick mounting holes, which can effectively avoid the deformation caused by excessive force when installing the panel. Some high-end products also use a transparent base to facilitate their own or an electrician's observation of the internal structure of the product. Some panels will reserve 6-8 (up, down, left, and right corners) fixed mounting holes, which are suitable for installation in a variety of situations. Seven, packaging and instructions. Brand products are very consumer-oriented, so the product packaging and manuals are unmatched by unqualified brand-name products. Imported brands must have Chinese instructions. Product names, brands, technical indicators, etc. are clearly marked, and everything from installation to safety precautions is also available. These are the things to be aware of when choosing a switch. Eight, safety certification. Qualified switch products must be certified by the state and meet international industry standards. Domestic products have to pass the 3C certification, 9000 series certification, some international brands have also obtained other national and international safety certification, these will be marked in the product itself, packaging or instructions.
The socket plug is distinguished from the appearance of two holes and three holes and has a round plug, a flat plug and a square plug. The types of sockets that are suitable for this are also numerous, with or without switches, and many with many additional safety functions and devices, such as sockets with fuses, safety doors or indicator lights.
When selecting outlets, products with protective doors should be selected as much as possible. Second, to check the degree of fastening of the socket clip, smooth insertion force is a key safety factor. At the same time, it is necessary to pay attention to the socket that matches the rated current of the household appliance, plug specifications, and junction box specifications. Do not use the so-called universal socket. The correct method should be what type of plug to use. Star language lights are visible, invisible, countless nights, a little light on my eyes, giving me strength. The lights are silent, but the light and the sound are in my heart. The power of the wind is in the eyes. Despite the bleak, cold night on the other side of the world, there is confusion. Gu Cheng said: The dark night gives me the dark eyes, I will use it to find light. Before the night had not covered the sky, I used to take it on the road and cross the jungle. Not only use it to illuminate the road ahead, but also make my heart stronger. The memory did not give me that life, but the light opened the door to my thoughts. There is a history of ups and downs in the enthused flames. I read the diligence of the people under the lamp, the sweet smell of sleep... They told the history of their fathers. The passing of time, I know that I cherish them is to treasure the time away.
Home Furnishings: Lighting Selection Tips
When we purchase household items, we must firmly grasp two points: one is functionality; the other is visual aesthetics. The functionality of a lamp in the home is particularly important because the functionality of a lamp is not only reflected in the illumination but also in the safety. In order to make all lights in your home work efficiently and safely, you need to be careful about the light sources (light bulbs, light tubes), switches, and sockets when you purchase. The safest and most secure way is to feel comfortable buying in the mall. Branded products, but how do you compare when brands come together? After consulting with several professionals, the reporter provided the following experience. Light Sources Currently, there are three types of light sources on the market: traditional light bulbs, light tubes, and energy-saving lamps. In addition, with the advancement of technology, there is an emerging light source, called semiconductor lighting. For traditional light bulbs and ordinary light pipes, the Chinese have spent decades and the production process is very mature. The quality of such light sources produced by most manufacturers can be guaranteed. However, the drawback of this type of light source is that it is easily depleted, and the voltage instability will cause it to “burn†off. Therefore, when using such a light source, it is necessary to pay attention to the removal of the lampshade to facilitate the replacement. Energy-saving lamps are becoming mainstream products on the market because of their advantages over traditional light sources such as power saving, long life, strong voltage adaptability, and high degree of reduction. Due to the higher profits of such products, large and small manufacturers have launched, so to buy energy-saving lamps should pay special attention. In general, the safety performance of the light source is intuitively reflected in the Great Wall logo and other safety certifications. In addition to the reference to these signs, it is advisable to test the lamp in the field when purchasing. The specific method is to install a cold light, the hand leaving the light, the power can be a lighter is best, here's "one light", it should be understood as the start flashing least or no flash, the root of the lamp No red light can appear. Some energy-saving lamps are equipped with a lamp line preheating circuit at startup, and there will be a delay of about 0.4 seconds during startup. Allow the lamp to work for a few minutes and observe if there is odor above the lamp when the temperature rises. Finally, look at the temperature of the lamp body after power off. The lower the temperature, the better. Good quality energy-saving lamps, there are several significant features, one can truly restore color, the second is a rich variety of color temperature. Energy-saving lamps commonly used color temperature levels ranging from 2700K-6400K, enough to meet the lighting needs of the family under various circumstances. The use of a low color temperature lamp with a temperature of 3000K or less will result in an incandescent lamp-like warmth. If you want a clear and bright lighting effect, it is appropriate to use a high color temperature lamp of 5000K or higher. When disassembling the energy-saving lamp, do not hold the lamp body in place so as to prevent it from breaking. For a lamp that has failed to start up, there may still be high voltage in some areas after the power is turned off. It is necessary to pay attention to safety. When the weather is too cold or the voltage is too low and the lamp starts to malfunction, do not leave the lamp in the high-current starting state of the lamp, and turn it on again quickly. Energy-saving lamps should pay attention to the use of the environment, do not use in high temperature, high humidity environment, especially compact energy-saving lamps, because of its internal high-frequency high-voltage operating conditions, heat dissipation conditions are slightly poor. Therefore, under the conditions of high temperature and high humidity, it is easy to cause the phenomenon of denaturation of magnetic materials and discharge between lines. Bathrooms and kitchens should try to avoid using such lights.
