First, open the panel of the plugin and lightly touch the switch, and you can see the internal structure of the switch. As for switches, pure silver contacts and conductive sheets made of silver hole composite materials should usually be used to prevent oxidation caused by arc during opening and closing. The conductive bridge of high-quality panels is made of silver nickel copper composite material. The conductivity of silver material is excellent, while the ability of silver nickel alloy to suppress arc is very strong, which ensures that our plug-in light touch switch can open and close more than 80000 times, far exceeding the international standard of 50000 times. The switch adopts brass screws for wire pressing, with a large and good contact surface, strong wire pressing ability, and stable and reliable wiring. Single hole wiring copper column with large wiring capacity, not limited by the thickness of the wire diameter. Customers can also refer to various specifications and parameters when choosing. In addition, the product panel is reserved with 6-8 fixed installation holes (upper, lower, left, right, and four corners), which are free and flexible, suitable for various installation needs, thus making the product more widely applicable.

Secondly, look at the appearance. The panel of high-quality plug-in touch switches should be made of advanced plastic products, with a uniform appearance and a smooth and textured surface. The plastic panel materials are all made of PC material (bulletproof adhesive) imported from General Motors of the United States, which has excellent flame retardancy, insulation, and impact resistance, and the material is stable and not easily discolored. The use of such materials to produce switches can greatly reduce the occurrence of fires and other situations caused by circuit reasons.

Finally, for consumers, the first thing to consider is the safety of the plug-in touch switch. The safety of the plug-in touch switch is essential, and you should try to choose products with ROHS and other product certificates when selecting touch switches. Secondly, it is necessary to check the tightness of the interior by lightly touching, as stable insertion force is a key factor. The light touch structure we have chosen breaks through traditional design and adopts a strong extrusion method, greatly enhancing the coordination of various internal components of the SMT light touch switch, eliminating the concern of heating during long-term use. At the same time, strong extrusion makes the components less likely to fall off, effectively reducing the occurrence of non human factors in power outage accidents. At the same time, high-quality tin Phosphor bronze is used as the hardware material, which has good electrical conductivity and strong fatigue resistance, ensuring 60000 times of pressing (the national standard is 50000 times of quality).
