The touch of the switch is very important. We can feel it when we use it. What is the specific situation? Let's give you a detailed introduction.

The influence of metal shrapnel on the switch: The light touch switch is evolved from the pot disc, which is the first thin film switch used. Its structure is single and its production speed is fast. However, the product has low life and single performance, which can not meet the market demand. According to the increasing demand for product performance, simple pot chips have been gradually eliminated by the market.
Then we touch the switch lightly, and the principle of its use is the same. It's an upgraded version of the pot chip, and its heart is the pot chip. It looks like Iron Man.
In the initial stage of use, consumers only have requirements for the quality and performance of products. With the improvement of market products and consumption level, the quality and performance of products begin to fail to meet consumers. As everyone familiar with this switch knows, the switch has its feel. Simply speaking, it is the strength of the switch. Touching, pushing, pulling and fretting these switches are all strength parameters. Industry standard: micro power 30-100 gf, button power 250-400 gf, power 200-400 gf, touch 50-400 gf.
The feel of the hand is directly related to the strength of the hand.
The smaller the range of positive and negative tolerances is, the better the feeling is. The positive and negative tolerances range of domestic produced shrapnel is larger, with a value of positive and negative 50. The positive and negative tolerances range of Korean produced shrapnel is medium, with a value of positive and negative 30. The Japanese imported shrapnel is also the best shrapnel in the world. The positive and negative tolerances range of Japanese ternary shrapnel used is very small, with a value of positive and negative 10.
Summary: The higher the precision of the shrapnel, the better the touch of the switch. The working principle of the switch is that the switch can be turned on by pressing the switch button at the working time point. When the button is loosened, the switch will be disconnected. The internal structure of the switch is realized by the force exerted by the metal shrapnel.
The metal shrapnel mentioned in the working principle is called shrapnel for short. There are two kinds of shrapnel materials. The shrapnel is made of phosphorus, copper and non-embroidered steel. The electroplating process includes silver plating and gold plating. The gold plating and silver plating processes are all above 0.3um. The electroplating process directly affects the electrical properties and oxidation resistance of the products.
Importance of hand feeling: There are many reasons for bad hand feeling, such as unreasonable structure of switch, substandard material of shrapnel and electroplating process, deformation of shrapnel and wide error range of shrapnel.
How can we ensure its hand feel, develop and produce reasonable structure, use non-embroidered steel shrapnel, control shrapnel error and bad rate of shrapnel? The quality of hand feeling will directly depend on the sales volume and word-of-mouth of the product. A good brand, a good product on the switch feel requirements are very high. The life of the switch itself is also greatly affected by the handle.
