How to deal with the surface of the miniature touch switch which we often use, and what is the specific treatment method? Let's give you a detailed introduction.
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.
Micro touch switch manufacturer analysis, grinding surface or sub-surface, the surface is composed of many dense and bumpy points, grinding surface looks calm, not publicized, occasionally scratched without leaving obvious traces. But the biggest problem is that the ground surface is easily dirty, dirty things make the text easy to leave traces, not easy to clean up, cleaning up is more troublesome.
Micro touch switch manufacturer introduced that the mainstream brand is still the most used surface polishing treatment, although easy to cause traces, but because the Dongguan touch switch installed on the wall is vertical, even if there are some small scratches are not obvious, in addition, because of the contact between the switch and the hand, so the probability of scratch is much smaller than the probability of grinding dirty surface.
The light touch switch structure closes the contacts formed on the diaphragm composed of the upper and the lower parts by pressing down the key heads. It is characterized in that a plurality of contacts are formed on the diaphragm below the key heads. The above multiple contacts are connected with each other by the pattern parts, and the light touch switch is connected to the above contacts at the same time, and the above multiple contacts are formed on the diaphragm below the key heads. The position of the part relative to the above key head is respectively provided with a protrusion part.
