Know before you buy
No, the Haimu Midnight switches come factory pre-lubed. They are designed to provide a smooth, consistent typing experience right out of the box without requiring additional manual lubrication.
These switches feature a standard MX-style cross mount, making them compatible with most hot-swappable mechanical keyboards that support Cherry MX-style switches.
The double-stage spring provides a snappier, more consistent rebound compared to standard single-stage springs. This results in a more responsive feel that helps the switch return to its starting position quickly after each press.
Yes, the housing is designed to optimize light diffusion. The switches are fully backlight compatible, allowing your keyboard's RGB lighting to shine through clearly.
The combination of a POM housing and a UPE stem creates a low-friction surface that ensures smooth travel throughout the keypress. These materials are chosen for their high wear resistance, contributing to the switch's 60-million-cycle lifespan.
The operation force of 50gf is the pressure required to register a keystroke, while the 60gf bottom-out force is the maximum resistance you feel when pressing the key all the way down. This creates a light, linear feel that is comfortable for both gaming and long typing sessions.
