THE USE AND PRESERVATION OF PUSH BUTTON

The push buttons should be firm and properly wired. Usually, a red button is regarded as the stop button, and a green or black button separately as the start or power one.

The push buttons should be checked frequently, and the dirt on its surface should be removed in time. Sealing measures should be taken if necessary.

If the push button is found to be in a poor contact, the cause should be identified; If any damage or dirt is found on the contact surface, it should be repaired or removed in time.

When the push button is used in high temperature situations, the plastic is easily aging and deformed due to heat, resulting in the button loosening. In order to prevent the short-circuit fault caused by the collision of wiring screws, the fastening ring or the insulating tube on the wiring screws should be added during the installation according to the situations.

The push button with the indicator light is generally not suitable for the occasion of a long power time, so as to avoid the clinker part being heated and deformed, resulting in the difficulty of replacing the bulb. If you want to use this kind of button, you can reduce the lamp voltage to extend its service life.

The push button or box for installing the push button should be made of metal material and connected to the mechanical general ground bus. And the suspended button should have a special ground wire.
