1. Ultra-small, lightweight and high-precision.
2. M2mm type with general purpose screws can be used.
3. The structure with formed terminals and reference distance at the same time makes it difficult for solder and flux to penetrate into the inside of the switch.
4. A low-power circuit type (Au clad contact) suitable for small voltage and current loads is also available.
5. Self-standing type terminal, easy to install on the printed board. The switch body is independent with respect to the printed board of 1.2~1.6mm.
6. There are also a series of right-angled and left-angled printed board terminals.
7. Compliant with RoHS directive.
Failure maintenance method of micro switch
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.
