Although switches and sockets are not the main materials in decoration, a wise choice can not only add color to your home, but also protect the safety of you, your family and family property. The size of the panel shall be consistent with the size of the embedded junction box; The surface is bright and clean, the brand mark is obvious, and there are anti-counterfeiting marks and the great wall mark of national electrician safety certification; When the switch is turned on, it feels flexible, the socket is stable, and the copper strip must have a certain thickness; The material of the panel should be flame retardant and strong

although switches and sockets are not the main materials in decoration, a wise choice can not only add color to your home, but also protect the safety of you, your family and family property

the size of the panel should be consistent with the size of the embedded junction box; The surface is bright and clean, the brand mark is obvious, and there are anti-counterfeiting marks and the great wall mark of national electrician safety certification; When the switch is turned on, it feels flexible, the socket is stable, and the copper strip must have a certain thickness; The material of the panel shall be flame retardant and robust; The height of the switch is generally 1200 to 1350 mm, 150 to 200 mm from the door edge of the door frame, and the height of the socket is generally 200 to 300 mm

whether the switch socket is safe or not is closely related to the connection mode of its internal wires. At present, the most advanced connection method is the quick connect terminal structure. This structural connection method is simple. Just insert the wire into the terminal part, and the connection is completed, but the wiring state is uniform, neat and firm. Even if a bowling ball is hung, the connection will not fall off. The live parts are not exposed, so there will be no danger of electric shock during construction

the device with protective door is also an embodiment of the safety of switch socket design. In life, young children often use their fingers or other objects to reach into the socket because of mischief and curiosity, resulting in many casualties. To this end, two automatic sliding plates are installed in the socket and socket. Only when the plug is inserted, the sliding plate slides to both sides to expose the socket; When the plug is pulled out, the slide is closed and the jack is blocked to avoid the above accidents

there are also switch sockets specially designed for kitchens and bathrooms. Splash proof boxes or plastic baffles are installed on the panel to effectively prevent the invasion of oil and water vapor, prolong the service life, and prevent short circuits caused by humidity

next, let's talk about the main points of the selection switch and socket:

first, materials:

the materials used in the panel of high-quality switches are excellent in terms of flame retardancy, insulation, impact resistance and moisture resistance. The materials are stable and not easy to change color. In addition to high-grade plastic, the current switch panel also has gold-plated, stainless steel, copper and other metal materials, providing people with more and more choices

II. Appearance:

the surface is bright and smooth, the color is uniform, and there is texture, which is generally a good product. In addition, the brand logo on the panel should be clear and full, and there should be no burrs on the surface

III. feel:

switches with good quality are mostly made of high-grade materials such as bulletproof glue, with high fire resistance, moisture resistance and impact resistance. The surface is smooth. The panel of good switches and sockets is required to be free of bubbles, scratches and stains. A good switch spring is moderately soft and hard, with excellent elasticity, and the turning point of opening and closing is relatively strong. The handle of the switch is light but not tight. A good switch usually has a hard spring and has a sense of strength when switching, while a poor switch is very soft, and even the switch handle often stops in the middle position. The jack of the socket shall be equipped with a protective door, and the plug shall be plugged in and out with a certain force, and one pin cannot be plugged in

you can also check the switch. High quality products will not feel light because they use a lot of copper and silver metal. Because the weight of a single switch is large only if the copper sheet inside the switch is thick, and the copper sheet inside is the most critical part of the switch. If it is alloy or thin copper sheet, it will not have the same weight and quality. 4、 Internal structure: switches usually use pure silver contacts and silver copper composite materials as conductive bridges, which can prevent oxidation caused by arc when opening and closing the switch. The conductive bridge of the high-quality panel adopts silver nickel copper composite material, which has excellent conductivity, and the silver nickel alloy has a very strong ability to suppress arc, which ensures that the switch can be opened and closed more than 80000 times, far exceeding the international standard of 40000 times. The switch with brass screw crimping has large contact surface, strong crimping ability and stable and reliable wiring. If it is a single hole copper terminal, the wiring capacity is large, and it is not limited by the thickness of the wire, which is very convenient. In addition, 6 ~ 8 fixed installation holes (up, down, left, right and four corners) are reserved on the product panel, which is free and flexible, and is suitable for the installation needs of various situations

socket for socket, the first thing to consider is its safety. The safety protection door of the socket is essential. When choosing the socket, you should try to choose the product with the protection door. Secondly, check the fastening degree of the socket clip, and the stable insertion force is a key factor. The structure of Qisheng socket clip breaks through the traditional design, and adopts the strong extrusion method, which greatly enhances the cooperation between the clip and the plug, and avoids the worry of heating during long-term use. At the same time, the strong extrusion makes the plug not easy to fall off, effectively reducing the occurrence of non-human power failure accidents. At the same time, the socket clip adopts high-quality tin phosphor bronze, which has good conductivity and strong fatigue resistance, ensuring that the number of socket plugging and unplugging reaches 10000 times (the national standard is 5000 times)

v. manufacturing process:

switches are often touched, especially color switch panels. If unqualified and inferior products are selected, they will age and fade over time. If you choose those switches that use materials with UV resistance and spray and bake the frame, even if they are used for a long time, the color will not change at all

VI. humanized design:

now, good switch panels have night indicator lights. Even the most traditional night indicator mode of fluorescent paint has developed from a single green fluorescence to a variety of colors. Power illumination is another way of indicating at night. At present, LED lamps are more used to replace neon lamps to ensure longer service life, lower heating rate and softer light. Some switches adopt grid structure panels and thickened mounting holes, which can effectively avoid the deformation caused by excessive force when installing the panel. Some high-end products also use transparent bases to facilitate their own or electricians to observe the internal structure of the product. Some panels will reserve 6-8 fixed installation holes (up, down, left, right and four corners), which are suitable for installation in various situations

VII. Packaging and instructions:

brand products attach great importance to consumer satisfaction, so the efforts in product packaging and instructions are unmatched by unqualified non brand products. Imported brands must be equipped with Chinese instructions. The product name, brand and technical indicators are clearly marked, and there are all kinds of precautions from installation to safety. These are all things you need to pay attention to when selecting the switch

VIII. Safety certification:

qualified switch products must have obtained national certification and meet international industry standards. Domestic products should pass 3C certification and ISO9000 series certification. Some international brands have also obtained other national and international safety certification, which will be marked in the product itself, packaging or instructions through identification. Such as Great Wall certification (CCEE), rated current and voltage

IX. service:

try to buy at the exclusive store or sales point designated by the regular manufacturer, and ask for the purchase invoice, so as to ensure that you can enjoy the after-sales service in the future
