The switch controls the opening and closing of the lamps in each living space of the home, and 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 very good in terms of flame retardancy, insulation, impact resistance and moisture resistance, and they 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 conductivity, while the silver-nickel alloy has a very strong arc suppression ability, 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 powerful. 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 resistance and is applied to the bezel by a spray coating process, the color will not change even if you use it for a longer period of time.
Sixth, human design. Nowadays, there are nighttime indicators on the good switch panel. Even the most traditional way of fluorescent paint night indications has evolved from a single green fluorescence to multiple colors. Power light is another way to indicate the night. At present, LED lights are used as a substitute for the lights to ensure longer life, lower heat generation 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 must pass 3C certification, ISO9000 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.
