Know before you buy
The 32g spring offers a very light, effortless typing experience, while the 40g spring provides a slightly more substantial feel with more resistance. Choose the 32g if you prefer a feather-light touch, or the 40g if you want a bit more feedback during rapid typing.
Yes, these are standard MX-style switches. They are compatible with most hot-swappable mechanical keyboards and custom builds that support 3-pin or 5-pin switches.
The LY stem is known for its exceptionally low friction, which contributes to the switch's signature smooth feel. The combination of a PC top housing and P4 bottom housing is engineered to provide a crisp, consistent sound profile and long-term durability.
Professional lubing and filming can significantly improve the smoothness and sound profile of your switches by reducing internal friction and housing wobble. If you want a refined, premium typing experience right out of the box without doing the manual work yourself, it is a worthwhile upgrade.
The 22mm spring is longer than standard springs, which creates a snappier return and a more consistent force curve throughout the keypress. This results in a more responsive feel that helps the switch snap back quickly after each stroke.
