Everyone is familiar with the mouse and the switch is not strange. What is the mouse microswitch? In fact, as long as we use the mouse, we will use the mouse microswitch. When operating the mouse button, the microswitch inside is constantly opening and closing, so as to realize the function of the mouse. Each mouse will experience dozens of key operations before it dies, and some faults will inevitably occur.
Generally speaking, after countless clicks, the mouse microswitch will have three faults:
First, there are metal fragments between the moving contact and the static contact of the mouse microswitch due to impact. These metal fragments may turn the click of the mouse into double-click. This kind of fault is easy to remove. As long as the static and dynamic contacts are polished and the debris is removed.
Second, due to the repeated impact of static and dynamic contacts, the contact point between the two is no longer smooth and there are some concave convex. Many times, one click of the mouse is not easy to use. It takes several more times to do it. This is the problem. To remove these concave convex points, the surface of the contact point needs to be polished smooth with a small file or fine sandpaper.
Third, after a long time of clicking, the spring plate will be tired, resulting in reduced elasticity. When the mouse is pressed, there will no longer be that crisp click sound. This fault is also easy to contact. As long as the U-shaped leaf of the spring is adjusted through the tool, the spring leaf can regain its elasticity.
Understanding the fault types of these common mouse microswitches and mastering simple fault handling methods can prolong the service life of our mouse. Of course, selecting microswitches with better quality can fundamentally reduce the probability of these faults.
