CHERRY MX key chattering
It seems I've stumbled upon a well-kept secret when it comes to mechanical keyboards that use Cherry MX switches (Kailh probably too). They all succumb to an issue - key chattering. Either something (dirt, dust, hair, ash, plastic dust, ...) gets inside the MX switch or it simply comes "of age" AND the switch starts to register as a double-click (but not each time). Sometimes it takes a year, sometimes less. It's a wide-spread issue.
How did I come to find that? My "g" key… See More
started experiencing "gg" sometimes instead of "g". I've noticed it a few days back (that it happens sometimes) but tonight it became really annoying. So I did some research.
Here are my findings:
- It affects all Cherry MX switch types (but some report MX Brown most frequntly).
- Sometimes cleaning the switch (while pressed) with compressed (canned) air can help (probably removes dust).
- Sometimes a few drops of Isopropyl alcohol (80% or stronger) and pressing the key rapidly makes the problem go away for a few weeks or even months.
- In a few rare cases lubricating the switch helped.
- If it happens on more than 1 key it might be the controler firmware (gone bad) or a driver conflict.
How to identify the issue if you're not certain?
- use a text editor and use the key you suspect
- use a program called Switch Hitter from Elite Keyboards
Is there a temporary "solution" to the problem?
- Yes there is. One can use a program called Keyboard Chattering Fix.

Is there a permanent solution?
- Yes, but it involves changing the switch for a new one.
But since all MX switches are affected, no-one can guarantee...
