Logitech Logitech G100S Mouse Resurrection: Change Cherry Cherry DG2 T85 Micro Motion

Additional changes (2016-10-13 15:43:14):
G100S micro switch is Omron's D2FC-F-7N (20M) white point fretting, which is a common micro-motion, known for long life can theoretically reach 20 million times, thank you @ Orthopaedic experts say

When I first bought the G100S, I played for the occasional game to make up for the empty windows that the mouse was taking away. Before I used the Logitech MX518 mouse, my friends used to know that it was a classic game mouse, feel and performance. Good, I usually play CS1.5, across the line of fire (winter and summer vacations and holidays do not play) and Warcraft, but unfortunately MX518 was taken away by my brother, it is an old mouse, and it took many years, but he I know the goods, but I also remember the MX518 I was taken away.

If you can, the first thing you want to change is IE3.0, but it's a pity that you don't like it. You don't like the current mouse, the colorful lanterns, and you've seen the Invigorating Pythons and Sairui, but they haven’t caught any special colds. It doesn't feel that flavor, but maybe, the classic influence of youth is too deep. Because of the good impression of MX518, Logitech's G100S was selected as the entry-level gaming mouse. The G100S is really an entry-level. No matter if it is too far away from the touch and keys and the MX518, the stroke of the keystrokes is simply a matter of course. The sound is slightly loud, especially at night, I prefer to work in the evening, so this experience is more obvious, the mouse took less than half a year to use it, recently felt that the left button is not easy to use, and each click needs to be pressed twice. Endured, but for a long time had a great influence on mood, and finally at a late night, bought a pair of micro-motion from a omnipotent treasure, ready to break with this left button.


Micro switch is quite a lot. For the first time, I didn't know what to choose. I bought Cherry Cherry DG2 T85, which is produced in Japan. I think the evaluation and sales are good. Think it must be better than me.

This article is a simple replacement. The gods do not shoot ha.

1, the replacement process:


Has not touched the iron for many years, once again picked up quite miss, just graduated internship in the electronics factory production line point iron. The left side of the bag is the newly bought micro-motion. Please ignore the soldering iron in the picture.

Cherry DG2 T85, serial number information: 235BT, 235 represents the 23rd week of 15 years, B is from Thursday to Saturday, T origin is Japan. If the product is genuine, this is Nissan's micro switch.


Screws are generally under the mat, conditional replacement of the micro switch is recommended when the replacement, or use hair dryer heating and then open tear, I do not recommend this, easy to degumming.

After all, it is a big factory. Logitech's workmanship is still very structured. The interior is a counterweight.

There is no fly line on the circuit board, and the inside of the mouse is very clean. It means that the main machine has not been used for a long time. Usually it is clean. This is true. Every time I use my computer, I wash my hands, wash the rags and wipe the keyboard. mouse. Open the door to know, G100S micro switch is Omron's D2FC-F-7N (20N) white point fretting, which is the most common micro-motion, known for long life can theoretically reach 2 million times, the actual use, you Understand that the other two micro-motions are Kay's, the model did not see, 100-yuan mouse will not give you too good micro-motion.

Because the right button can still be used, and I use very little, so I just plan to replace the left button, the back to see the welding point, there is no Weld, the joint is even and full, remove the three pins on OK.

Removed micro switch

There is a direction when installing, pay attention to look, do not install wrong.

Because of my own operation, the process of disassembling the soldering iron cannot be photographed. The heating time must be shorter, and the smaller the number, the better. Otherwise, the PCB is easy to fall off.

The last is full of blood resurrection, and after the replacement of the left key really good, fast response, there is no loud voice, and the right key is very clear, right and so on in the future and then change it again, this time the replacement is still personal comparison Satisfied, the time is short, ten minutes to get, hope that the micro-motion of cherry can be more durable.

2. Some suggestions:

1 The use of electric iron still requires a certain amount of proficiency. The area on the circuit board is small, and there are many components. The method must be steady. If you accidentally fly a few, then maintenance will be very complicated. Be careful; there must be heating time is short, within 3 seconds, the power of electric iron is not too much, and now is also very cheap to adjust the temperature of the iron; I did not use the suction device, to tell the truth, that stuff is not used to used a few times, In the past, when the maintenance was done, the tin wire was used. The effect was good. Then the excess solder was supposed to do it. Gravity! , It will be a bad habit to develop before. It is not recommended to imitate it.

2 The replacement of micro-motion is very suitable for the maintenance of the left mouse button problem, do not know before buying, or may consider the import of Omron's gray point. So homework is also very important.

3 There is a pin that can be empty and not need to be welded. It is also convenient for the next time to be empty. However, the fun of DIY is just here. It is still advisable to find an old mouse beforehand.
