How to test the quality of Membrane Switch

2021-11-30

At present, the goods used in society are products that pass inspection, quality and safety and do less harm to human body. Only in this way can they be accepted by consumers and popular in society. Without inspection standards, products are difficult to circulate in the society and realize value; For the sake of safety, high quality testing standards are very necessary. Membrane switch has a wide range of applications and can be seen in major equipment. Its detection can not be relaxed, otherwise it will have a significant impact.

Only genuine Membrane Switch can be reflected in the use process, and still be strong at the time of inspection. The general process of Membrane Switch detection cannot be relaxed, otherwise it will cause great harm to human body. The following steps are required to check whether the quality of the film switch is qualified: there shall be no obvious difference in the color of the same batch of products, and the color printing layer shall have sufficient covering power, subject to the color and structure below which can not be seen by the reflected light; When printing the transparent ink layer, the two-color overlapping part shall not exceed 1mm, and the color deviation caused thereby is allowed; The edges of printed characters and color blocks are not clear, no more than 0.15mm. The size of the Membrane Switch shall comply with the provisions in Table 1. The parallelism and perpendicularity of two adjacent sides of the membrane switch shall comply with the provisions. The center distance between adjacent conductors at the end of the lead strip is generally 2.54mm. This is the basic detection standard, among which there are more complex detection standards.
No matter what the high-quality Membrane Switch detection standard is, it is to enable the qualified membrane switch to be applied, so that it can produce the best effect in the process of use, and reduce the occurrence of major bad things due to poor quality.
