Analysis of the causes of damage to the mouse micro switch
Ordinary mice will inevitably be damaged after being used for a period of time, and most of the reasons for the damage of the mouse are the failure of the buttons. The probability of failure of other components in the mouse is actually very small. It is the micro switch under the button that determines whether the mouse button is sensitive. There are reasons for the frequent use of the button, and the problem of low-quality micro-switches used by some cottage manufacturers. We can use our own hands to replace the mouse with high-quality micro-motion, so that the mouse buttons feel better, while the lifespan is also extended, and the value is also increased.
There are many types of micro switches. There are hundreds of types of internal structures. According to the volume, they are divided into ordinary, small and ultra-small; according to the protection performance, there are waterproof, dustproof, and explosion-proof types; according to the breaking type, there are Single type, double type, multi-connected type. There is also a strong disconnection micro switch (when the reed of the switch does not work, the external force can also make the switch open); according to the breaking capacity, there are ordinary type, DC type, micro current type, and large current type. According to the use environment, there are ordinary type, high temperature resistant type (250℃), super high temperature resistant ceramic type (400℃).
The basic type of micro switch is generally without auxiliary pressing attachment, and it is derived from small stroke type and large stroke type. Different auxiliary pressing accessories can be added according to the needs. According to the different pressing accessories added, the switch can be divided into various forms such as button type, reed roller type, lever roller type, short boom type, long boom type, etc.
