Information

1. The button should be checked frequently to remove dirt on it. Due to the small distance between the contacts of the button, when used for many years or when the seal is not good, dust or oil emulsion of various stages will flow in, which will cause insulation reduction and even short circuit accidents. In this case, insulation and cleaning must be performed, and corresponding sealing measures must be taken.


2. When the button is used in high-temperature occasions, it is easy to deform and age the plastic, causing the button to loosen, causing short circuit between the connection screws. According to the situation, a tightening ring can be used for tightening during installation, or an insulating plastic tube can be added at the connection screw to prevent loosening.


3. If poor contact is found, the cause should be investigated: if the contact surface is damaged, it can be trimmed with a fine file; if the contact surface has dust or soot, it should be wiped clean with a clean cotton cloth dipped in solvent; if the contact spring fails , It should be replaced; if the contact is severely damaged, the product should be replaced.


4. For the button with indicator light, because the bulb needs to heat up, it is easy to deform the plastic lampshade for a long time, which makes it difficult to replace the bulb. Therefore, it should not be used in places with long power-on time; if you want to use it, you can appropriately reduce the lamp voltage and extend its service life.
