Common faults and solutions of mouse micro switch
The application fields of micro switches are very wide. The mouse is the most contacted in daily life. For example, the buttons are not working well, and a single click becomes a double click. These are the mouse micro switches that often appear. What are the common faults that the mouse micro switch is prone to?

The application fields of micro switches are very wide. The mouse is the most contacted in daily life. For example, the buttons are not working well, and a single click becomes a double click. These are the mouse micro switches that often appear. What are the common faults that the mouse micro switch is prone to?
Common fault 1: Due to the frequent impact of the dynamic and static contacts, the surface of the static contacts is not smooth, and many convex and concave points appear. Row. For this kind of failure, we only need to use a very small file or fine sandpaper to smooth the surface.
Common fault 2: The moving contact and the static contact will produce metal debris, which is caused by the collision between them. And this debris will cause a mouse click to become a double click. We can fix it just by clearing the debris.
Common fault 3: After a long click of the mouse, the spring sheet will be fatigued, and the spring will be weak. There's no crisp clicking sound when pressed like a new mouse. We know that the main reason for the weak bounce is the mechanical deformation of the spring leaf. The smaller the degree of the U-shaped arc of the spring piece, the smaller its elastic force; on the contrary, the larger the arc, the greater its elastic force. Understanding this, we have a solution to this problem. The method is very simple, as long as we turn the U-shaped part of the spring sheet upwards, press the spring sheet with a tool, and increase the degree of the U-shaped arc, the spring sheet will regain its elasticity.
Since the mouse needs to be clicked for a long time, it has high requirements on the service life and quality of the micro switch, otherwise the above failure problems are prone to occur.
