As we all know, the seemingly inconspicuous appearance of the tact switch is of great practical value. As for the tact switch itself, it has precise structure, material, craftsmanship, etc. So among the many factors, what affects the overall quality of the tact switch?
For tact switches, the material and coating of the shrapnel and contacts are the most critical. The material and process of the shrapnel and contacts need not only consider their electrical properties, but also take into account their service life. In general, in order to reduce the contact resistance between the shrapnel and the contacts, brass or phosphor bronze materials are mostly used, and the electroplating is silver-plated.
If you encounter iron pins, silver plating can isolate SO2 gas in the air and keep it away from corrosive elements; but the corrosion protection time is short. It would be better to use brass or phosphor bronze pins. Therefore, the thickness of the material and the silver-plated layer and its processing become the keys to determine the overall performance of the pins. In today's market, the thickness of the most high-quality silver plating on the market is above 0.3 microns, which can even open up to three times the gap with the inferior thickness.
