Three kinds of pot with a little bit of：
One. Why do you want to bring a little pot, with the point has to play what role?
We know that the pot is not a little early, but most Metal dome now has a contact of four contacts and five contacts. In fact, the pot with the main reason is to increase the friction between products and stickers, not easy to deviate from the conductive parts during operation.
Two. Why does the pan piece piece appear different strength and size?
Efforts to directly determine the operator's feelings, but also directly affect the machine, for example a small products we use switch limits the strength between the 130-350gf, so if it is a lot of large machinery and equipment are keys that also use this kind of strength, caused by the result is either talk not up, or press down feeling not to have to complete the operation. Due to the use of low intensity Metal dome by product demand.
Three. Metal dome life why not all high high and low life?
It is easy for us to accept a fact is the product of better quality products prices higher, Metal dome is the same product life of the higher price is higher, if a product a day use the buttons are not two or three times, but not for a couple of years to be replaced, the figure is about 10000, and send the number of waste could not reach 1 00000, so with a reach 1 00000 times life can be done, who would spend more than the cost to use a two hundred thousand times even higher lifetime Metal dome. At the same time we also draw a reason, in the case does not affect the use of products, can reduce the cost will be as far as possible to reduce costs, so the pot has a different kind of life.
Four. Pot on the surface of the film, why should be treated?
The vast majority of electronic products are to use to Metal dome, some products will be exposed, some products may be exposed to acidic items or special smell and so on, influence Metal dome conductive performance and service life. In order to deal with these reasons, the surface is treated with silver plating, gold plating, tin plating, nickel plating and so on.
