What customers say
Kailh Box Marshmallow switches are highly praised by enthusiasts for delivering an exceptionally light and smooth linear typing experience. Their defining feature is the ultra-light 35g actuation force, which users love for significantly reducing finger fatigue during long sessions, describing the feel as effortless. Reviewers consistently note excellent factory lubrication, ensuring superb performance straight out of the box without modification. The Box design also enhances keycap stability and dust resistance, boosting perceived quality. While this extreme lightness is perfect for light typists, some users accustomed to heavier switches report accidental presses. Overall, the Marshmallows offer a premium, unique feel that satisfies those specifically seeking the ultimate low-force linear switch.
Know before you buy
The Linear version provides a smooth, consistent keystroke using POM material. The Tactile version offers a noticeable bump for feedback without the noise, while the Clicky Tactile version adds an audible 'click' sound to that feedback using a transparent PC case.
These switches use an MX-style cross stem and are compatible with any keyboard that supports Cherry MX-style switches. They are designed for custom builds, so ensure your PCB supports hot-swappable or solderable MX-style switches.
The BOX structure surrounds the stem to provide extra stability, reducing keycap wobble during use. Additionally, this design offers enhanced dust and moisture resistance, which helps maintain consistent performance over time.
Yes, the Kailh Box Marshmallow switches are backlight compatible. The Clicky Tactile variant features a transparent PC case, which is particularly effective at diffusing light for a brighter aesthetic.
Linear switches are often preferred for gaming due to their smooth, rapid-fire nature and lower operating force. Tactile and Clicky Tactile switches are generally favored for typing, as the physical feedback helps confirm each keypress and improves accuracy.
The Linear switch has a total travel distance of 4.0mm, while the Tactile and Clicky Tactile variants have shorter travel distances of 3.4mm and 3.6mm respectively. This means the Tactile and Clicky versions will bottom out slightly faster than the Linear model.
