How to handle the surface of the switch panel? What are the ways? The following is a detailed introduction to you.
There are generally two kinds of surface treatment for switchboard, polishing and grinding, both of which have their advantages and disadvantages.
The characteristic of the switching switch is that it is installed in the machine and instrument in progress. Most of the time it is in the position of the initial free state. It only changes to the second state (position) when the external force is required. Once the external force is removed, the switch will return to the original position due to the action of the spring.
