Introduction to tact switch

Tact switch is a kind of electronic key switch, he is divided into patch plug-in subdivided then there are a lot of types, in these categories, the most conventional are generally four feet patch or plug-in, of course, tact switch is a kind of special needs of customized products, his shape and size is not a certain provision, according to the product of the actual requirements of him to open the mold to manufacture, which also embodies the flexibility of the light switch, but also because of this aspect of the performance of the tact switch has been widely used.

Tact switch as an electronic key switch, in use gently press the switch button can make the switch on, when you release your hand when the switch is disconnected, its internal structure is to rely on the metal shrapnel force bouncing to realize this series of functions, which the only work in the internal metal shrapnel, the shrapnel alone service life of up to 1,000,000 times, the use of the internal life of the tact switch is not as optimistic as this. The life span of this shrapnel alone can reach 1,000,000 times, but the life span inside the Tact switch is not so optimistic, and the current domestic data shows that the highest life span can reach 100,000 times.

Tact switch due to its small size and light weight in electronic products on a wide range of applications such as: digital products, remote control, communication products, household appliances, security products, toys, computer products, fitness equipment, medical equipment, money detector pens, laser pointer keys and so on. But tact switch also has its shortcomings, so some electrical buttons use conductive rubber or pot switch directly instead, such as the remote control and laptop computers.

 Tact switch internal use of metal shrapnel, that is, the so-called pot chip switch, in the operation process can be conductive, do not operate the state will not have the current through, and secondly, the working principle of the tact switch is also very simple, the initial state of the metal shrapnel for the state of the raised, through force operation for the concave and tact switch below the foot conductive parts of the contact current through to Complete the work. The use of this also do not carry out too many cumbersome operations, as long as the button handle downward press can realize a certain function of the product, because of this simple operation and has a suitable for the actual needs of electronic products and a very good feel of the keys to get more products used.
