Many of the electrical appliances we use will use tactile switches, so what do you know about transparent touch switches? Don't know it! Let's take a look at the introduction below.
Transparent touch switch is basically an electronic switch that everyone uses every day, don't you believe it? So say, have you ever used a cell phone? A telephone? TV? A rice cooker?. a common transparent and light touch switch. There's always a lot of you used, transparent touch for every day. How much do you know about the switch?
One, what is a transparent touch switch
As mentioned in the previous article, most of the electronic devices we have used are transparent and light touch switches, so what exactly is it? What are the advantages that can be put into use in a wide range? No hurry, let's get to know it first.
The definition of Baidu encyclopedia is very simple. In one sentence, "an electronic switch belongs to the category of electronic components." This is mainly about the nature and type of it. It is too professional and tedious about this aspect. To understand something, first to know what it looks like, then what is the mystery of the switch? It is as follows:
This is the real feature of a component, that is, its structure. Through this picture, you can understand its internal structure clearly, but it is not necessary for a friend without a hands-on switch to understand this step, only to know that it is the key to the remote control, the keypad of the keyboard, MP3 and MP. 4 buttons, rice cooker buttons, and all electrical keys are inside the structure shown in this picture, and they are all transparent touch switches.
Two, the working principle of transparent touch switch
There is no such experience when you press the remote, that is to have a certain elasticity when the button is pressed, which is actually its working principle. In the internal structure of the transparent touch switch, there is a part that is important, that is the "reaction spring," which explains why a flexible hand is made when the button is pressed. Feeling, when you press it, the tiny force that produces it will close the switch and press it once again, and the switch will break, just as if you first press a button on the boot, the TV sets on, and then it turns off.
Three. How to choose and buy high quality transparent touch switch
First, to see the material, transparent and light touch switch basic material for brass or phosphor copper, low grade material is iron, the outer layer will be plated on a silver, but the thickness of silver plating will directly affect the quality of the switch, the thickness of more than 0.3um for the back silver, generally is better, 0.2um for thin silver, to 0.1um is plating white. That's right.
Second, the performance of the switch is also reflected in the conductivity, transparent touch switch is contact point and flake, the greater the contact surface, the better the performance.
Third, the lighter the voice and the key, the longer the life expectancy.
The above is a little knowledge about the knowledge of transparent touch switches. I hope you can get some results after reading.
