3 pushbutttons explosion proof switch , plastic motor control station

Description:

The push button switch refers to a switch that pushes the transmission mechanism with a button to make the movable contact and the static contact open or close and realize circuit switching. The push button switch is a main electric appliance with a simple structure and a wide application. In the electrical automatic control circuit, it is used to manually send out control signals to control contactors, relays, electromagnetic starters, and the like.

maintenance:

(1) The button should be checked frequently to remove dirt from it. Due to the small contact spacing of the buttons, after years of use or when the seals are not good, dust or oil emulsions flow into the emulsion, which may cause insulation degradation or even short-circuit accidents. In this case, insulation and cleaning must be carried out and appropriate sealing measures are taken.
(2) When the button is used in high temperature, it is easy to deform the plastic and cause the button to loosen, causing the contact screw to be short-circuited. According to the situation, a tightening ring can be used for tightening during installation, or an insulating plastic tube can be added at the terminal screw to prevent loosening.
(3) Buttons with indicator lights Because the bulbs are heated, it is difficult to replace the plastic bulbs for a long time. Therefore, it should not be used in places with long power-on time; if you want to use it, you can reduce the voltage of the bulb and prolong its service life.
(4) If the contact is found to be bad, the cause should be ascertained: if the contact surface is damaged, it can be trimmed with fine enamel; if the contact surface is dust or ash, it should be cleaned with a clean cotton cloth with 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.
