Today, I will explain to you whether the light touch switch will turn yellow after a long time of use. Please see the details below.
Touch the switch for a long time, its appearance will gradually become yellow, what is the cause? The light touch switch manufacturer gives a detailed explanation to this situation.
Touch switch is widely used in daily life and manufacturers. Some customers reported that the light touch switch would turn yellow after melting or reflow welding.
After reflow welding, the light touch switch will turn yellow. Most of them are made of 6T plastic. Because 6T plastic itself absorbs water relatively simply, if the plastic absorbs less water, the button measured after heating is not obvious. However, if the absorbed water has a large contrast, the discoloration is very obvious, but it does not affect the function and service life of the button, because the change is only the appearance color of the button. Many customers mistakenly believe that buttons are not heat-resistant, which is not the case. If it is not high temperature resistant, it may be caused by plastic base deformation or plastic base melting and elastic deformation. If the customer is still worried that this kind of situation will affect the quality of touch switch, it is recommended that the customer choose LCP material. Because LCP material is fragile and not easy to absorb water, it will not change the color of the switch after reflow welding.
