How to Guarantee the Hand Feeling of the Light Touch Switch

Release time:2019-05-06    Clicks: Click

 
When we choose and use the touch switch, we are more concerned about the touch of the touch switch, so how can we ensure the consistency of the touch switch feel? Let's give you a detailed introduction.
Touch switch is a very common electronic switch in our daily life, I believe that its principle, common specifications, circuits, scope of use and other information should not be introduced, we have explained a lot of the previous also explained a lot. Now that I'm going to write an article again today, there are new discoveries. Some common problems about light-touch switches are the problems I raised in business communication for customers and the problems we found in our own R&D and production process and the solutions to them. Then I'll tell you and popularize knowledge to you. Our broadcasting middlemen are blessed. Come on and praise them.
The action type of the light touch switch is the light touch return. Normally, the common press force is 160 GF and 250 gf, and its return force is 50 gf. Above, we said that the normal keystrokes are 160 and 250, which is what we will focus on today. Many manufacturers on the market use domestic shrapnel produced in Jiangsu and Zhejiang to save costs, and then call it Korean shrapnel. As an old salesman, I have never heard that there are fork manufacturers in Korea that produce lightly touched and lightly touched shrapnel. Of course, it is understandable to boast appropriately as a business and factory. That is, because domestic shrapnel is used, its strength and hand feel can not be controlled. It's very precise. Normally it's 160 + 50 GF and 250 GF + 50 gf. I'm surprised to see this data, but it doesn't matter that the positive and negative tolerances we praise are within < 30 gf.
According to what I said, I wonder if you have found any problems. Some professional purchases will ask you what kind of shrapnel you are using. Yeah, what kind of shrapnel is the best material for touch switches? Many people use phosphorus-copper shrapnel in order to pull orders and save costs. It has the advantage that the life of phosphorus-copper shrapnel can reach the standard. Another better advantage is that it is cheap, but the disadvantage is that the range of positive and negative tolerances is large. Pingzan uses ternary shrapnel imported from Japan. The material of shrapnel is stainless steel. The toughness of stainless steel is very good. Its characteristics are high life, good handle and high cost. Both of them are very difficult for lightly touching switch manufacturers to choose from. I believe many people will be troubled by them, but we do quality, and more cost factors should be left to customers to consider.
We have laid the groundwork for so much knowledge in front of us, and now we are going to focus on it. Many customers find that the touch of light switch is very bad after using it. For example, we have 10 light switch. I press each switch. After pressing it, we will find that each switch feels different. Like a roller coaster, it will be heavy and light. If your product is a single dosage, you can't find this problem, and you don't need to consider that customers will react to it. Problem, because there's no problem with functionality. But if you have a lot of touch buttons on the control board, then your problem comes. As a design engineer, it's better to consider and avoid this problem. As a light touch switch manufacturer, how do we ensure the consistency of the touch of the light touch switch? First of all, we need to analyze the reasons for its occurrence. Above, we said that the shrapnel has two kinds of materials. After high temperature, the phosphor-copper shrapnel will attenuate. Its positive and negative tolerances are (+50gf). After the furnace, it will become lighter and attenuate. For example, the switch of 160gf will also be in the range of 110 gf, but after the furnace, its feel is only 100 gf, which is the lower limit. What if the upper limit is 200 gf? Then you press the switch and it will have 100 GF and 200 GF feel strength, which is what we said before roller coaster feel. If imported stainless steel shrapnel is used, it will not decay and will maintain good consistency. Take 160gf for example, the upper limit is 190gf, and the lower limit is 130gf. If this is the range, we normal people can not feel its change. Therefore, to ensure the consistency of touch switch feel, we need to choose imported stainless steel shrapnel from Japan. If you want to choose high-end touch, Praise Electronics should be your best choice.
