Characteristics of Siemens switch products
1, the product itself has the design function of talking, which makes the electrical performance better, occupies less space, leaves enough wiring space in the installation box, makes the installation easier, has convenient boundary, is environmentally friendly and uses less materials;
2. The whole core metal parts of the product are punched in rows at one time by leading technology, which abandons the traditional rivet installation method and is safer and more energy-saving;
3. The product contains a unique Siemens patented circuit breaker terminal, which can ensure that the wiring compaction effect is no less than that of the screw wiring method, so that the wire pressing does not hurt the wire, and at the same time, it can compact the wire exposed without pain.
The product itself has an oversized wiring hole, which is convenient for operation; 4. The base is made of full PC injection molding, with exquisite workmanship, smoothness and integrity, no flash and burr, clear product labels on the base, clear instructions on the power cord, elegant appearance, corrosion resistance, torque resistance, shear resistance and longer service life;
5. The product is designed with a closed arc-extinguishing switch, and its intercepting piece is made of the best copper alloy, with a thickness of 0.8mm, and the silver alloy contact with a diameter of 3mm is selected to optimize the internal structure;
6. The main body of Siemens electronic products meets the requirements of ROHS directive, which is safe and environmentally friendly and at the leading level in the industry. The optimized circuit performance of electronic products is safer and more reliable, the anti-overload and surge ability is greatly improved, and the signal receiving ability is stronger.
Authenticity identification of Siemens switch
Generally speaking, Siemens switches are double anti-counterfeiting. If the Siemens products you buy are not double anti-counterfeiting, they are probably fakes.
Of course, double anti-counterfeiting products do not mean they are real. 2. Siemens switch is made of PC material, and its surface is very bright. If the surface of the product you buy has no luster, it is likely to be replaced by other materials, which belongs to the category of fake goods.
Many people think that brand products must look good, which is a wrong view. The appearance of authentic Siemens switch is ugly, because its structure is similar to the 4.0 series developed by TCL97 in 1997, and its appearance has evolved from this structure, so it really has no advantage in external light. Of course, the fake products will decorate it beautifully. So if the product you buy is beautiful, it is probably a fake.
4. The genuine Siemens switch has a black base, while the fake Siemens switch is generally transparent. Of course, it is black, but when you smell it, you will find a pungent smell coming out.
5. The copper sheet of the socket itself is also an important position for identification. Authentic copper is an exception, ensuring the same color, which can be checked by a blade. Because phosphor copper is used and fake brass is used, there is color difference inside and outside.
6. In addition, the shell opening of the switch panel is also the focus of inspection. If two corners are put together in good condition, they are genuine; if they are broken, they are fake.
Siemens switch procurement
1, look at the appearance
The panels of high-quality switches and sockets should be made of high-grade plastic products, which look uniform in material and smooth and textured in surface. The panel materials are all PC materials (bullet-proof glue) imported from American General Company, which have excellent flame retardancy, insulation and impact resistance, stable materials and are not easy to change color. Switches and sockets made of this material can greatly reduce the occurrence of fires caused by circuit reasons.
2. Look at the internal structure
As far as switches are concerned, pure silver contacts and conductive strips made of silver-copper composite materials should usually be used to prevent oxidation caused by arc when opening and closing. The conductive bridge of high-quality panel is made of silver-nickel-copper composite material. Silver material has excellent conductivity, while silver-nickel alloy has very strong ability to suppress arc. The switch is pressed with brass screws.
Large and good contact surface, strong wire pressing ability and stable and reliable wiring. Single-hole connection copper column has large connection capacity and is not limited by wire diameter. 3. Safety
The safety door of the socket is essential. When choosing sockets, try to choose products with doors. Secondly, check the fastening degree of the socket clip, and the smooth insertion force is a key factor. At the same time, strong extrusion makes the plug difficult to fall off, effectively reducing the occurrence of non-human power outages. At the same time, the socket clip is made of high-quality tin-phosphorus bronze, which has good conductivity and strong fatigue resistance, and ensures that the socket times are 10000 times (5000 times according to the national standard).
