Tips for purchasing touch switch

Time:2022/6/27Author:adminClick: 690
1、 No conduction when lightly pressed



When using the product, many consumers often find that pressing the key doesn't respond. It takes a lot of force to press it, and the product has a functional response. Because our switches are exposed to the air, many finished products are not sealed, and consumer electronic products need heat dissipation. In wet weather, the shrapnel of the switch is easy to be oxidized. After oxidation, the contact performance is not as good as before, that is, there is a problem that the switch cannot be connected when pressed lightly. Many consumers also removed the switch and found that there would be a small black spot on the shrapnel, which is the effect of oxidation of shrapnel. Therefore, it is suggested that the electronic products we do not normally use should be placed in a relatively dry place, and the prepaid electronic parts should be oxidized.



2、 High resistance



At present, many customers do not know much about the resistance value of the switch. Generally, our switch resistance value is controlled below 30m Ω. However, if the resistance is high, it means that the contact area between the spring and pin pin pin of the switch is too small. A small contact area will cause the switch not to contact. Once the switch is not contacted, it will be bad.
