With the continuous development of science and technology, the utilization rate of light touch switch is increasing year by year. This is because the light touch switch itself has a strong sensitivity, it can replace people to complete a lot of work, thus liberating people's hands. The manufacturing process of light touch switch itself is also very complex. First, there are many problems in the selection of materials that people should pay attention to. The choice of materials not only needs low price, but also needs firmness and durability. At the same time, it has certain resistance to moisture, heat and other environments. Once the switch is not properly selected in materials, it will bring great trouble to the future use, and the internal structure of today's household appliances is very complex, even if it is a complex process to open the box for repair, so people have now avoided opening the box frequently for repair. More and more professionals remind the manufacturers of light touch switch that they need to control the quality of materials at the beginning, which will bring great convenience to the later manufacturers.

The first choice of materials should have a very good ability to fight against the special environment. In the hot summer, the air temperature is very high. Many switch materials will melt because they can't stand the high temperature. This will have a certain impact on the use of products. In the cold winter, many materials will become very fragile because of the low temperature, a little touch will break, resulting in product damage. Therefore, the material selection of the switch should consider the maximum and minimum temperature it can bear. Only by ensuring that the material will not deform or damage in extreme cases can it be proved to be an optional material suitable for the production of switches. The same high humidity will also cause a certain degree of corrosion and damage to the materials. Many experiments have proved that if the indoor is not too large, for example, in the rainy days in the south in summer, many materials will fail. This is because the water vapor content in the air is more, resulting in conductivity, so it can not be more sensitive to be controlled. Therefore, the more control switches are used in extreme environment, the more strict quality control is needed in materials, and some special materials with corrosion resistance, high temperature and humidity resistance are selected to be refined. Only when the control switches are well grasped, can strict control of the whole machine be formed.

Secondly, when selecting materials, we should also pay attention to whether it has a certain degree of waterproof and electrical insulation function. This is mainly due to people's safety considerations. At present, most of the household appliances are used at home, so for the safety of people's use, the choice of materials must be able to insulate electricity and waterproof. If the selected material is not very sensitive to electricity and water, it will cause a certain degree of security risks and bring great harm to human beings. Generally speaking, before the production of the light touch switch, the material will be tested many times to prove that it can be well isolated from water or electricity. Especially in the special environment, such as the rainy season in summer or the time of exposure to the sun, whether the electrical isolation ability of the machine has declined or not needs to be considered before production. Only by ensuring safety as the first principle can we put into production in large quantities.
