Application of light touch switch on electronic products

Tactile switches are very useful in electronic products, so what are their uses? Now let me give you a detailed introduction.
Light touch switch we all know is an electronic button switch, it is generally welded to the PCB board, of course, there are special card on the circuit board, so a small button can be used in which products? Now the electronics industry is so-called rapid development, I do not know how many electronic products can use buttons, in so many electronic products, how many will touch the switch? Let's take an analysis of the use of the tactile switch.
Light touch switch is also a conductive medium, it can control the flow through and off, whether the structure or operation is relatively simple, in the cost is also relatively low, and is a small resistance charge button products, so this switch has been widely used in electronic products, it can be said that the keys less. A circuit breaker or circuit board with sufficient space can be used with a touch switch.
However, considering the cost and assembly problems, many electronic products still do not touch the switch, but with the pot chip or pot chip sticker, a more cost-effective product to replace, in the function will not be affected, do not weld in the assembly, more convenient than touch the switch, then under what circumstances do not use Under what circumstances should a light touch switch be used?
Light touch switch has a good fixed performance and the base with a certain degree of heat resistance, are soldered on a single PCB board, in the fixed can be said to be very solid. And has a certain protective capacity, there is a waterproof light touch switch, can work in a certain depth of water for a period of time without damage. But it is not as good as the film switch in the sense of operation and precision, so the light touch switch is at a disadvantage in the high-end intelligent equipment at present, and may be replaced by the film switch, because the light touch switch has some function film switch also has, and the film switch feel good process precision and so on all due to it, but in the high-end intelligent equipment. Cost is much higher than the touch switch, so in high-end and low-end electronic products are generally used touch switch or pot sticker and so on these buttons.
Light touch switch occupies more space than pot chip, and generally needs a circuit board, can not complete the work alone, which is different from self-locking switch, self-locking switch can be used directly wiring, but the circuit board does not necessarily touch the switch, because to take into account the advantages of various buttons, this product Membrane switches should be used if you need a high precision hand feel. You may need less space and more boards and keys. You may use pot stickers or pot stickers. If you don't have high precision requirements, you only need good fixing performance, better protection, and a little waterproof function can be lightly touched. Close.
