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.
Mouse microswitch design features< /strong>
The biggest technical feature of micro switch manufacturers in switch design is to prevent loss and prolong its service life. Fretting loss is divided into two types: wear and fatigue. Fretting wear means contact surface wear or material loss; fretting fatigue refers to the generation of fatigue cracks in metals and other materials or the reduction of fatigue life.
Increasing the strength of the contact element surface is the main way to slow down the loss. It increases surface residual compressive stress through various surface treatments, such as physical (laser, ion implantation, etc. to change the surface microstructure hardening technology), chemical (surface hardening technology such as carburizing, nitriding, etc.), mechanical (shot peening, rolling, etc.) ) process to obtain special composition, structure and properties on the surface of the material to improve its wear resistance and fatigue resistance. In addition, there are also ways to strengthen the electrical capabilities of the easily fatigued metal reeds and contacts, such as switching to metal materials such as silver and alloys.
Changes in structural design can also have the effect of slowing down the loss. For example, changing the internal geometry of the component, clamping method, contact size, etc., also changes the pressure distribution and contact mode at the contact surface, which can improve the performance of anti-fretting damage to varying degrees. Another effective measure to slow down the fretting loss is to reduce the coefficient of friction (ie frictional force), which can be achieved by increasing the lubricating medium.
Characteristics comparison of microswitches of various brands span>
| Branding to fit the crowd | Main Model Features | |
| OMRON | OMRON is a professional manufacturer of industrial micro switches. It started to produce mouse micro switches in response to the needs of Microsoft, Razer and other mouse brands. Based on the professional foundation, OMRON's micro switches It has a wider range of adaptability, as long as friends who do not have special hand feel requirements can choose. | It belongs to the middle key travel switch, with moderate feel, fast rebound speed, moderate strength and moderate noise. |
| Panasonic | The brand and quality of Panasonic do not need to be mentioned too much. From the micro-motion trial group, it is more inclined to business people. Because of its long key stroke and fast rebound speed, it has a sense of rhythm. More difficult to grasp, more difficult to control for novices, but a good enjoyment for business people. | The key travel is long, the hand feel is moderate, the rebound speed is fast, the force is large, and the noise is small. |
| IC | IC's micro-motion is especially suitable for users who like mechanical feeling. It is worth mentioning that IC's micro-motion has a strong sense of rhythm and is easy to grasp. Said it was a good choice. | Long key travel, hard feel, fast rebound, high strength and loud noise |
| TROX | It is very similar to the German character. TROX's fretting is very rough, but it is very practical, suitable for users who prefer a hard feel. | The key stroke is long, the hand feel is hard, the rebound speed is fast, the force is strong, and the noise is moderate. |
| ZIPPY | As a Taiwanese brand of ZIP, the micro-motion is very good, especially suitable for game users who like to train quietly by themselves, and it is also very suitable for ordinary users and business users. , it is not suitable for users who like a hard feel. | The key travel is short, the hand feel is very soft, the rebound speed is very fast, and the noise is small |
A normal mouse will inevitably be damaged after a period of use , and most of the reasons for mouse damage are the failure of the buttons, and the probability of failure of other components inside the mouse is actually very small. What determines whether the buttons of the mouse are sensitive or not is the micro switch under the button, which is used frequently. There is also the problem that some cottage manufacturers use inferior domestic micro-motion. We can replace the mouse with high-quality micro-motion by ourselves, so that the mouse buttons feel better, and the lifespan is also extended, and the value of the mouse is also followed. Improve.
