Som vi alle ved, er der en enorm praktisk værdi bag touch-kontaktens tilsyneladende ydmyge udseende. Når vi bruger berøringskontakten, oplever vi ikke kun dens fremragende ledningsevne, bekvemme kontrolmetoder osv., men oplever også dens behagelige knapfølelse. Hvad angår selve taktkontakten, har den en præcis struktur, materiale, håndværk osv., så blandt de mange faktorer, hvad påvirker den overordnede kvalitet af taktkontakten? Tag et kig.
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{{0}}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.
Endelig berøringskontaktens ledningsevne. For i den fysiske struktur er taktkontakten afhængig af granatsplinter og kontakter til at lede, så nøglen til dens indflydelse ligger i kontaktpunktets struktur. Generelt set er jo større kontaktfladen, jo bedre, og den krydsformede kontaktflade af kontaktfladen på taktkontakten på HRO Hanrong-dele er det bedste valg.
