Know before you buy
The Hibiscus R3 features a standard 5-pin MX-style mount, making them compatible with most hot-swappable mechanical keyboards. If your keyboard only supports 3-pin switches, you can easily clip the two plastic guide pins off the bottom of the switch to make them fit.
No, these switches come factory-lubed for immediate smoothness right out of the box. They are designed to provide a consistent, refined typing experience without the need for manual modification.
The 42g actuation force is considered a light-to-medium weight, which is ideal for reducing finger fatigue during extended typing or gaming sessions. It offers enough resistance to prevent accidental key presses while remaining effortless to actuate.
These switches are engineered for a 'HiFi' acoustic experience, characterized by a muted bottom-out and a pleasant mid-low frequency sound. They are significantly quieter than standard clicky or tactile switches, making them a great choice for shared office or home environments.
The actuation force of 42g is the pressure required to register a keypress, while the 48g bottom-out force is the resistance felt when you press the key all the way down. This tight margin between the two provides a snappy, responsive feel that prevents the switch from feeling mushy.
