There are two kinds of surface treatment for micro touch switch, polishing and grinding. Both methods have their advantages and disadvantages.
The characteristic of the light touch switch is that it is installed in the machine and instrument in progress. Most of the time, it is in the position of initial free state. Only when there is a requirement, it will change to the second state (position) under the action of external force. Once the external force is removed, the switch will return to the initial position due to the action of spring.
Polishing surface treatment is also called mirror treatment, the surface is smooth, surface mirror polishing surface treatment, the biggest advantage is that dirty things are not easy to clean, and the surface is smooth, gloss is good, looks more beautiful, air; and occasional shortcomings will lead to small friction from the beginning.
