Use And Maintenance Of Button Switches
Aug 12, 2021
(1) Check the button frequently to remove the dirt on it. Due to the small contact distance of the button, after years of use or when the seal is not good, the inflow of dust or oil in various stages of emulsion will cause the insulation to decrease and even short-circuit accidents. In this case, insulation and cleaning must be done, and corresponding sealing measures must be taken.
(2) When the button is used in a high-temperature environment, it is easy to deform and age the plastic, causing the button to loosen, causing a short circuit between the terminal screws. According to the situation, a fastening ring can be added to tighten it for use during installation, or an insulating plastic tube can be added to the wiring screw to prevent loosening.
(3) For the button with indicator light, the bulb will heat up, and the plastic lampshade will be deformed for a long time, which will make it difficult to replace the bulb. Therefore, it is not suitable to be used in places where the power is on for a long time; if you want to use it, you can appropriately lower the bulb voltage to extend its life.
(4) If poor contact is found, the reason should be investigated: if the contact surface is damaged, it can be repaired 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 it is a contact spring If it fails, it should be replaced; if the contact is severely burned, the product should be replaced.
