Touch the handle of the switch is a key situation, so when we select it, we will put the handle first. What is the specific situation? We need to introduce it to you below.
Touch switch is a very common electronic switch in our daily life. I believe that its principle, common specifications, circuit, scope of use and other information should not be introduced. We have explained a lot and explained a lot before. Since I will write an article again today, it is a new discovery. Some common problems related to tapping the switch are the problems I put forward in business communication for customers and the problems we found in our own R & D and production process and the solutions. Then I will tell you and popularize knowledge for you. We are blessed to play a wide range of middlemen. Please hurry up and praise!
The action type of tap switch is tap return. Normally, our common button strength is 160gf and 250gf, and its return force is 50gf. As mentioned above, the normal button strength is 160 and 250, which is what we will focus on today. In order to save costs, many manufacturers in the market use domestic shrapnel produced in Jiangsu and Zhejiang Province, and then it is called Korean shrapnel. As an old salesman, I have never heard that there are manufacturers in South Korea that produce light touch and light touch shrapnel. Of course, as a business and a factory, it is understandable to boast appropriately, that is, because domestic shrapnel is used, its strength and feel cannot be controlled The system is very precise, normally 160 ± 50gf and 250gf ± 50gf. I'm surprised to see this data, but it doesn't matter that the positive and negative tolerances of our products are within ± 30gf.
According to the above questions, I don't know if you find any problems? Some professional purchasers will ask what kind of shrapnel are you using? Yes. What kind of shrapnel material is the best for touch switch? Many people use phosphor copper shrapnel in order to pull single and save cost. One of the advantages of phosphor copper shrapnel is that its service life can reach the standard. The other advantage is that it is cheap, and the disadvantage is that it has a large range of positive and negative tolerance. Pinzan uses three-dimensional shrapnel imported from Japan. The material of shrapnel is stainless steel, and the toughness of stainless steel is very good. Its characteristics are high life, good feel, and high cost. It's hard for manufacturers to choose between the two. I believe many people will be troubled by this, but we are making quality, and more cost factors should be left to customers to consider.
We have laid so much knowledge in front of us. Now we have to focus on it. Many customers find that the touch of the switch is very bad after using. For example, we have 10 touch switches. I press each switch. After pressing each switch, we will find that the touch of each switch is not the same. It's like a roller coaster. It's heavy and light for a while. If you use a single product, you can't find this problem, and you don't need to think about the customer's reaction Problem, because there is no problem with the function. But if you have a lot of touch buttons on your control board, then your problem is coming. As a design engineer, it's better to consider and avoid this problem. As a touch switch manufacturer, how can we ensure the consistency of touch switch feel? First of all, we need to analyze the cause of its occurrence. As we said above, there are two kinds of materials for shrapnel. After high temperature, the phosphor copper shrapnel will have the problem of attenuation. Its positive and negative tolerance is ± 50gf, which will become lighter after passing through the furnace, that is to say, it will decay. For example, the switch of 160gf at 110gf also conforms to the range, but after passing through the furnace, its hand feel is only 100gf, which is the lower limit. What if the upper limit is 200gf? Then the switch you press will have a feel of 100gf and 200gf, which is the same as the roller coaster. If the imported stainless steel shrapnel is used, it will not decay and will maintain good consistency. Take 160gf. The upper limit is 190gf and the lower limit is 130gf. If it's in this range, we normal people can't feel its change. Therefore, to ensure the consistency of the touch of the switch, you need to choose the stainless steel shrapnel imported from Japan. If you want to choose the high-end touch, pinzan electronics should be your best choice.
The above is the knowledge of touch switch in hand feeling, so we must have these requirements and choices.
