What factors affect the quality of tact switches?
as we all know, underneath the seemingly humble appearance of the touch switch is a huge practical value. when we use the touch switch, we not only experience its excellent conduction performance, convenient control methods, etc., but also experience its comfortable button feel. as for the tact switch itself, it has a precise structure, material, craftsmanship, etc., so among the many factors, what affects the overall quality of the tact switch? take a look.
for a tact switch, the material and plating of its shrapnel and contacts are the most critical. the material and technology of the shrapnel and contacts not only need to take into account their electrical performance, but also take into account the issue of their service life. in general, in order to reduce the contact resistance between the shrapnel and the contacts, brass or phosphor copper is often used, and the electroplating is silver-plated. if it is encountered with iron pins, silver plating can isolate the so2 gas in the air and keep it away from corrosive elements; but the anti-corrosion time is shorter. it would be better to use brass or phosphor bronze pins. therefore, the material and the thickness of the silver-plated layer and its processing have become the key to determining the overall performance of the pin. in today's market, the most high-quality silver-plated thickness on the market is above 0.3 microns, which can even be separated from the inferior thickness. three times the gap. the silver plating process also has a wide range of effects. some pins are directly plated with silver, while some adopt a multi-layer electroplating process, first with nickel plating or pre-copper plating and so on.
finally, the conduction performance of the touch switch. because in the physical structure, the tact switch relies on the shrapnel and contacts to conduct, so the key to its influence lies in the structure of the contact point. generally speaking, the larger the contact surface, the better, and the cross-shaped contact surface of the tact switch contacts of hro hanrong parts is the best choice.
