We often use metal buttons in our lives. We should check the button frequently, remove dirt from it. Due to the small spacing of the contact of the button, after many years of use or poor seals, dust or emulsions of various stages of oil will flow in, which will cause insulation reduction or even short circuit accidents. In this case, insulation and cleaning must be carried out and corresponding sealing measures must be taken.
When the button is used in high-temperature occasions, it is easy to deform and age the plastic, resulting in loose button and causing a short circuit between the wiring screws. According to the situation, a fastening ring can be added to tighten the installation and use, and an insulating plastic pipe can also be added to the wiring screw to prevent loosening.
If poor contact is found, the cause should be ascertained: if the contact surface is damaged, it can be trimmed with a fine file; If there is dirt or soot on the contact surface, it should be wiped clean with a clean cotton cloth dipped in solvent; If the contact spring fails, it should be replaced; If the contacts are severely burned, the product should be replaced.
