Introduction to mouse microswitches
The micro switch in the mouse is a component that is triggered by a metal reed inside. After the button on the mouse is pressed once, the silver point in the front section of the metal reed in the micro switch is triggered once with the contact foot below, causing the circuit to be turned on. Sends an electrical signal to the computer and then resets it. There are many kinds of mouse micro switches, and there are hundreds of internal structures. The mouse microswitch is generally based on an unassisted pressing accessory as the basic type, and a small stroke type and a large stroke type are derived.
Under all the buttons on the mouse, there must be a micro switch or a tact switch, so in fact, the micro switch is the button of the mouse, and the function of the button on the mouse shell is only to facilitate the user to press the micro switch. Not only for the mouse, but also for various other toys.

Ordinary mice are inevitably damaged after a period of use, and most of the reasons for mouse damage are the failure of the buttons and the internal The probability of other components failing is actually very small. And it is the micro switch under the button that determines whether the mouse button is sensitive or not. There are both the reasons why the button is frequently used, and the problem that some cottage manufacturers use inferior domestic micro switches. We can replace the mouse with high-quality micro-motion by ourselves, so that the button of the mouse feels better, and at the same time, the lifespan is extended, and the value of the mouse is also increased.

Classification of microswitches
There are many types of micro switches, and there are hundreds of internal structures. According to the volume, there are ordinary, small, and ultra-small; according to the protection performance, there are waterproof, dust-proof, and explosion-proof types; Single type, double type, multi-link type. There is also a strong disconnect micro switch (when the reed of the switch does not work, the external force can also make the switch disconnect); according to the breaking capacity, there are ordinary type, DC type, micro-current type, and high-current type. According to the use environment, there are ordinary type, high temperature resistant type (250 ℃), super high temperature resistant ceramic type (400 ℃).
Micro switches are generally based on unassisted pressing accessories as the basic type, and small stroke types and large stroke types are derived. Different auxiliary pressing accessories can be added according to the needs. According to the different pressing accessories added, the switches can be divided into various forms such as button type, reed roller type, lever roller type, short boom type, long boom type and so on.
Micro switches are used for automatic control and safety protection in equipment that requires frequent circuit switching, and are widely used in electronic equipment, instrumentation, mining, power systems, household appliances, electrical equipment, as well as aerospace, aviation, ships, missiles, Military fields such as tanks have been widely used in the above fields. Although the switch is small, it plays an irreplaceable role.
At present, the micro switches on the domestic market have different mechanical lifespans ranging from 3W times to 1000W times according to different requirements. Generally, there are 10W times, 20W times, 50W times, 100W times, 300W times, 500W times and 800W times. They are generally used in China. Beryllium bronze, tin bronze, and stainless steel wire are used as reeds. Foreign ALPS can reach 1000W times. Their reeds are made of rare metal titanium.

Application of microswitches
Such as computer mouse, car mouse, automotive electronic products, communication equipment, military products, testing equipment, gas water heaters, gas stoves, small household appliances, microwave ovens, rice cookers, floating ball equipment, medical equipment, building automation, power tools and general Electrical and radio equipment, 24-hour timer, etc.
