What kind of products can tact switch be used on?

We all know that tact switch is a kind of electronic key switch, it is generally soldered on the PCB board, of course, there are also special needs to be stuck in the circuit board, then a such a small key can be used in which products above? Now the electronic industry is the so-called rapid development, I do not know how many electronic products will use the key, in so many electronic products and how many will use the light touch switch? Below to bring you to analyze what uses of tact switch.

Tact switch is also a conductive medium, it can control the current through and off, whether it is the structure or operation is relatively simple, in the cost of cost is also relatively low, and is a kind of resistance load smaller key products, so this switch in electronic products have been widely used, can be said that the key is less, there is enough room for circuit boards or circuit boards can be used tact switch. switch. 

But taking into account the cost and assembly and other issues, many electronic products still do not use the tact switch, but with the pot chip or pot chip sticker this more low-cost products to replace, in function will not be affected in any way, do not weld on the assembly, more convenient than the tact switch, then in what case do not use the tact switch in what case to use the tact switch? In what cases should the tact switch be used? tact switch has a very good fixed performance and base with a certain temperature resistance, are single individually welded on the PCB board, can be said to be very solid in the fixed. And has a certain protection ability, there is a waterproof tact switch, can be in a certain depth of water inside the work for a period of time without damage. But in the operation feel and precision is not as good as the membrane switch, so at present that is the high-end intelligent equipment tact switch is at a disadvantage, may be replaced by the membrane switch, because tact switch has the function of the membrane switch also has, and the membrane switch feel good process precision and so on due to it, but in the cost of cost is much higher than tact switch, thus in the middle and high and low end electronic products, the tact switch can be used for a period of time. Thus, in the high and low-end electronic products are generally used on the tact switch or pot chip sticker and so on these buttons. 

Tact switch in the space occupation is higher than the pot piece, and generally need a circuit board, can not complete the work alone, this point is different from the self-locking switch, self-locking switch can be directly connected to the line can be used, but there are circuit boards will not necessarily use the tact switch, because to take into account a variety of advantages of the keys, this product may require high precision feel good should use the membrane switch, may require less space, should use the keypad. Membrane switches, may need less space on the board and more keys, may use the pot chip or pot chip sticker, if the precision is not very high requirements, only need to fix the performance of a good point, better protection, and a little bit of waterproof function can be used in the tact switch.
