< p > light touch switch manufacturer about switch quality affected by what factors? As we all know, the seemingly unremarkable shape of the tap switch is hidden under the great practical value. When we use the touch switch, we not only experience its excellent conduction performance, convenient control mode, but also experience its comfortable button feel. For the light touch switch itself, it has a precise structure, material, process, etc., so among the many factors, what affects the comprehensive quality of the light touch switch? Let's find out.
For the touch switch, the material and coating of the shrapnel and contact are the most critical. The material and process of shrapnel and contacts need to take into account not only their electrical properties, but also their service life. In general, in order to reduce the contact resistance between the shrapnel and the contact, the material of brass or phosphor copper is used, and the electroplating is a silver plating layer. If it is encountered iron pins, silver plating can isolate SO2 gas in the air, so that it is away from corrosive elements; But the anti-corrosion time is short. The use of brass or phosphor copper pins will be better. Therefore, the material and the thickness of the silver plating layer and its process treatment become the key to determine the comprehensive performance of the pin, in today's market, the best quality silver plating thickness on the market is above 0.3 microns, and the inferior thickness can even open three times the gap. The silver plating process also has a very different impact, some pins are directly silver plated, and some use multi-layer plating process, nickel plating or pre-copper plating and so on.
Finally, the conduction performance of the tap switch. Because in the physical structure, the tap switch relies on the shrapnel and the contact to conduct, so the key to its impact is the structure of the contact point. In general, the larger the contact surface, the better, and HRO Hanrong's light touch switch contact for the cross type contact surface is the best choice.
