Such a small light touch switch should be how to detect, in fact, very simple specific detection methods below to give you a detailed introduction.

The detection method of light touch switch with lamp is very simple. As long as it is touched or pressed lightly, we can observe the sense of Carlton when it is pressed and the sensitivity of reaction. Whether it is a large light touch switch or a small light touch switch, it can make people feel that the operation is simple and easy.
Many materials with light touch switch have the effect of dust-proof and electricity-insulating, so they should be carefully maintained in daily use. People can start with light touch switch, which is an insulating material, to eliminate more potential production hazards. In daily maintenance and detection of light touch switch, we should pay attention to whether there is a reason for light touch switch. Quality problems such as fragility, deterioration of sensitivity, or cracking due to aging.
If there is abnormal operation of light touch switch, remember not to disassemble without authorization. This is a very dangerous practice. There is no professional maintenance environment. Many high-end electrical products need to be opened in a dust-insulated environment, because the dust will have the effect of conductivity. Touch the switch lightly. The inspection and maintenance with light touch must be carried out in a special environment.
Because of the high sensitivity of the light touch switch, we should pay attention not to over-squeeze when pressing, because the control button on the precision instrument or the simple button on it all have the same principle. When using the light touch switch itself, the sensitivity will be reduced if the light touch switch is pressed or struck vigorously. Sensitivity.
Because of its small size, long life and light touch, it has been widely used in many fields, such as household appliances. With the continuous improvement of people's living standards, these household appliances will be updated faster and faster, and the number of them will become larger and larger. This is also the greatest potential for us to look forward to its development prospects. Direction of force.
In order to improve the service life of ultra-small light touch switch, it is particularly important to select high-quality light touch switch. Looking at the contact point of light touch switch is a common method when we select light touch switch. Here are some methods of selecting high-quality light touch switch.
Selection of lightly touch switch ultra-small lightly touch switch method 1, first of all, pin base material, lightly touch switch pin base material is brass or phosphorus copper (low grade is iron). In order to reduce contact resistance, pin is basically silver plated, SO2 gas in silver encounter air will oxidize, directly affecting the solderability and contact resistance of the switch, so high-quality products. The quality of light touch switch should be controlled in the silver plating thickness of the pin base material and the silver plating process.
Selection of ultra-small light touch switch method 2, factory inspection methods and items also affect the quality of the final light touch switch, such as appearance, feel, conduction, resistance and other items are spot checked or full checked, such as some large factories require waste rate to be measured by PPM or zero defect, it is necessary to set up after factory inspection set up full checking. Sampling inspection or quality inspection.
Selection of ultra-small light-touch switch method 3, with accessories, the ultimate impact on quality is the assembly process, assembly process depends on the management ability of the production company, staff quality meaning and quality assurance ability and other factors, different assurance ability of light-touch switch to the final product quality will certainly be different, and now the market assembler.  There are manpower and machine, because the current automation capability is being further improved, so there are advantages and disadvantages: machine assembly cost is low, but product quality is low, and manual assembly cost is high, but the quality is high.
Selection of ultra-small lightly touch switch method 4, life and feel is the combination of lightly touch switch stroke and shrapnel, the shorter the travel, the lighter the sound, the longer the life, on the contrary, in the fixed shrapnel process, mainly depends on the travel or sound to determine the life of lightly touch switch, in addition, the key to determine the life of shrapnel. The factor is stamping technology.
The key factor affecting the conduction reliability is the structure of the contact point. Because the function of the light touch switch is to conduct contact between contact point and shrapnel, the larger the contact surface is, the better the contact surface is. The contact surface is determined by the structure. There are probably three types of structures in the market. The order of advantages and disadvantages is as follows: Bubble (volcano). Mouth type), "O contact", slotted type "2 contact", flat foam type "1 contact".
