The switch controls the opening and closing of the lamps in the living space of the home. The socket ensures the stable and safe power connection of the household appliances. In a well-decorated home, the selection of good switches and sockets can become the crowning touch of the home environment. But when choosing a switch socket, the most important thing is to have good safety performance, which is reflected in eight aspects.
First, the material. The materials used in the panel of high-quality switch are excellent in flame retardancy, insulation, impact resistance and moisture resistance. The material has strong stability and is not easy to change color. In addition to high-grade plastics, the current switch panels are also available in gold-plated, stainless steel, copper and other metal materials, providing people with more and more choices.
Second, the appearance. The surface is smooth and smooth, the color is uniform, and the texture is generally good. In addition, the brand logo on the panel should be clear and full, and the surface must not have any burrs.
Third, the internal structure. The switch usually uses pure silver contacts and a silver-copper composite material to make a conductive bridge, which prevents the arc from causing oxidation when the switch is opened and closed. The high-quality panel's conductive bridge is made of silver-nickel-copper composite material. The silver material has excellent electrical conductivity, and the silver-nickel alloy has a strong ability to suppress arcing. This ensures that the switch can be opened and closed more than 80,000 times, far exceeding the international regulations. 40,000 times of standards. The switch with brass screw pressure line has large contact surface, strong pressing capacity and stable and reliable wiring. If it is a single-hole wiring copper column, the wiring capacity is large, and it is not limited by the thickness of the wire, which is very convenient.
Fourth, feel. Try the switch, the good switch spring is soft and moderate, the elasticity is excellent, and the turning of the opening and closing is more powerful. A situation in which the switch button is stopped at a certain position in the middle does not occur and becomes a serious fire hazard. It is also possible to use a switch, and the high-quality products will not have a light feeling because of the large amount of copper-silver metal.
Fifth, the production process. The switch is often touched, especially the color switch panel. If the unqualified inferior product is selected, it will fade and fade after a long time. If you select a switch that uses materials that have UV resistance and that are painted on the frame, the color will not change at all even after a long period of time.
Sixth, humanized design. Now, there are night lights on good switch panels, even the most traditional fluorescent paint nighttime indications, from single green fluorescence to multiple colors. Power light is another way of nighttime indication. At present, LED lights are used instead of daylights to ensure longer life, lower heat generation rate and softer light. Some switches use a grid structure panel and a thick mounting hole, which can effectively avoid the deformation caused by excessive force when installing the panel. Some high-end products also use a transparent base to allow them or the electrician to observe the internal structure of the product. Some panels will reserve 6-8 (up, down, left, and right) fixed mounting holes, which are suitable for installation in a variety of situations.
Seven, packaging and instructions. Brand products pay great attention to consumer satisfaction, so the effort in product packaging and manuals is unmatched by unqualified brand-name products. Imported brands must be accompanied by Chinese manuals. The product name, brand, technical indicators, etc. are clearly marked, from installation to safety precautions. These are all things to be aware of when choosing a switch.
Eight, safety certification. Qualified switch products must be nationally certified and meet international industry standards. Domestic products must pass 3C certification and ISO9000 series certification. Some international brands have also obtained other national and international safety certifications, which will be marked in the product itself, packaging or instructions.
