Lubing mechanical switches is a rite of passage for any keyboard enthusiast. While it may seem tedious to open and lubricate dozens of tiny plastic components, the results are undeniably worth the effort. Applying a high-quality lubricant, such as Krytox 205g0 for linear switches or TriboSys 3203 for tactiles, dramatically reduces scratchiness and spring ping.
The process involves carefully brushing a thin layer of lube onto the stem rails, the bottom housing, and the spring. A well-lubed switch feels buttery smooth and produces a deeper, more refined sound profile. To make the process easier, many builders use a lube station to organize the disassembled parts.
Remember, less is more when it comes to lubing; over-lubing can make the switch feel sluggish and ruin the tactile bump. For tactile switches, it is generally recommended to avoid lubing the legs of the stem entirely, as this is where the tactile feedback originates. A light application on the rails and housing is sufficient to smooth out the keystroke without sacrificing the tactile experience.
Spring lubing is another important step often overlooked by beginners. Unlubed springs can produce a high-pitched “ping” sound that resonates through the keyboard case. Bag lubing springs with a small amount of Krytox 105 oil is a quick and effective way to eliminate this issue. With practice, the entire lubing process becomes a therapeutic and rewarding part of the keyboard building hobby.
