A mouse is composed of a casing, a PCB circuit board, a sensor, a micro switch and several other parts. The casing affects the overall grip, the sensor is related to the positioning accuracy of the mouse, and the micro switch affects the feel of the buttons. Factors that most users are very concerned about when purchasing a mouse. And a good micro switch can ensure a long-term uniform feel, and also determines the use time of this mouse in your hand, the importance of which is self-evident.
In order to improve the feel of the buttons, major manufacturers have also made great efforts in the selection of mouse structure and micro switches. Different solutions such as welding-free replacement of micro-motion, button tension system, and adjustable button triggering force are aimed at bringing users Better button feel and service life. The author has also compiled some little secrets about micro-motion here, and then I will share them with you.
The current types of micro switches can be divided into traditional micro switches, silent micro switches, optical micro switches, etc. In addition to the well-known OMRON, there are also Panasonic Panasonic, CHERRY Cherry, Korean IC (actually Taiwan DICGU) , Taiwan ZIPPY, etc. The products of traditional manufacturers have a good market share, good reputation and product reliability, while new brands have won good market response and consumer recognition with their innovative technologies. At present, many manufacturers also directly use their own customized micro-motion, all aiming to bring consumers a better user experience.
The traditional micro switch adopts a metal reed trigger structure. When the button is pressed once, the metal reed in the micro switch triggers once, and sends an electrical signal to the computer, and then resets to achieve the trigger effect. However, after long-term use, there are problems of physical wear and oxidation, which will lead to poor contact, or the position of the contacts may be offset, resulting in failure to trigger, double-click and other problems. At present, manufacturers use different methods to increase the wear resistance of the spring sheet to improve the life, or use alloy materials to enhance the electrical performance of the contact part.
Optical micro switch is a new type of micro switch launched in recent years. It uses optical principles and optical coupling technology to achieve connectivity, with less physical wear and loss, and longer service life. Opto-magnetic fretting is to realize signal change through light blocking/conduction in optical fretting, which can better avoid the problems of dust and contact oxidation. Strong magnetic components can also quickly absorb light-shielding components to avoid vibration and solve the problem of metal The aging problem of the shrapnel can greatly improve the life of the micro switch and reduce the failure rate.
The mute fretting mostly adopts the square origin fretting, which is mostly used for office use. The buttons feel more dull and fleshy, but there is no traditional fretting "Click" sound, which is more suitable for offices, libraries and other places that need to be kept quiet.
Brief introduction of brand micro-motion model:
As long as microswitches are mentioned, users who know something will definitely think of OMRON first. They frequently appear in the microswitches used in mass-produced mice, and their various models can also satisfy manufacturers or users for microswitches. Different needs of moving switches. OMRON's micro-motion models basically correspond to the color of the switch, and are divided into white dots, red dots, green dots, gray dots, blue dots, etc. The origin is divided into domestic and Nissan. Silver alloy contacts are generally used in domestic production, and gold alloy contacts are generally used in the Japanese version. The product life will also be indicated on the back of some micro-motion models, such as common (10M), (20M), (50M) and so on.
-Omron's most well-known micro-motion model should be D2FC-F-7N, which is often referred to as white point micro-motion. However, the lifespan is only 5 million times, and the problem of double-clicking is prone to occur after a long time, which is also a point criticized by many users. The lifespan of D2FC-F-7N (10M) and D2FC-F-7N (20M) introduced later has been greatly extended, and it is also a micro switch that is used more frequently by many manufacturers at present. Some meat, the overall performance is also reasonable, the follow-up OF enhanced version also further make up for some defects, more durable than the original. And Omron also successfully occupied the first position of the mouse micro switch by virtue of the excellent performance of the D2FC-F-7N series of micro switches. Of course, the success of the 7N series is also inseparable from the driving role of a variety of classic gaming mice. While opening its popularity, it has also won the recognition of the market and consumers with its excellent product quality.
-The fretting of CHERRY is the same as the shaft body, the materials and workmanship are also excellent, and the product life and quality are also better than similar products. DG2 black dot fretting is also one of the best, using gold alloy contacts, the key life is about 10 million. The downforce of the black dot fretting is about 0.74N. Although the hand feel is a little harder, the rebound is compact and the stroke is short, which is very suitable for continuous and fast clicking. The overall performance is very good, and it is also recommended by game enthusiasts. The gaming mouse with split buttons can bring a better button experience.
-TTC micro-motion is also a common kind of mouse micro-motion. It not only has rich product models, but also has excellent comprehensive cost performance. It is mostly used for left and right buttons, side buttons and other parts. SteelSeries' Kinzu, Kana, Razer's Viper, Hell Snake and other classic mice all have TTC in them.
Since everyone likes the feel is different, the experience of a micro-motion will also be very different. If you want to find your favorite button feel, you still need to experience and test it yourself.
