Kailh Box V2 Red is a linear mechanical switch from Kailh released in February 2023 with a 40 gf operating force and 1.8 mm pre-travel, 3.6 mm total travel, and a manufacturer rating of At least 80 million keystrokes.
Three focused profiles from published switch specifications. No overall score is generated because feel and use case are personal.
Measures actuation, travel, and force. Shorter, lighter movement favors speed. Advanced input features add capability.
Measures bump or click intensity. It uses feel type and tactile-force rise. Higher scores mean stronger feedback.
Measures published lifespan evidence. It uses documented construction details. It does not predict real-world reliability.

The Kailh Box V2 Red elevates the budget linear standard with upgraded molds, factory lubrication, and an extended spring. The longer spring provides a lively, responsive upward push that makes every keypress feel buoyant and agile. Sound tests demonstrate a clean, well-damped clack that avoids hollow ping thanks to improved housing tolerances. Five-pin PCB mounting pins ensure a rock-solid seat in hot-swap sockets, keeping switches firmly aligned. The enclosed IP56 box architecture keeps the gold-plated electrical contacts clean and reliable over tens of millions of strokes. Mounting these switches on a gasket-mounted plate with thick PBT keycaps yields a poppy, smooth typing feel.

Compare Kailh Box V2 Red with another keyboard switch to see differences in feel, force, travel, and compatibility.
Explore switches with similar technology, feel, form factor, operating force, and travel.
The Kailh Box V2 Red is a Mechanical switch from Kailh with a Linear feel, so its keypress character is primarily defined by that mechanism and feedback style.
The Kailh Box V2 Red has an operating force of 40 gf. That is a light switch feel suited to users who prefer easy keypresses.
The Kailh Box V2 Red has a pre-travel of 1.8 mm. Shorter actuation distances usually feel quicker because the key registers earlier in the press.
The Kailh Box V2 Red has a total travel distance of 3.6 mm. Total travel describes the full stroke from rest to bottom-out.
The Kailh Box V2 Red is listed as 5-pin, MX keycap compatibility is yes, and hot-swap compatibility is yes. Always match the switch pins and keyboard PCB/socket before buying.
Yes. The Kailh Box V2 Red is listed as factory lubed. Factory lubrication can affect out-of-box smoothness and sound, but its effect can vary with the keyboard build and keycaps.
Available sound-related specs for the Kailh Box V2 Red include sound profile: Clacky, sound level: Low. Case, plate, keycaps, and desk mat can still change the final keyboard sound.
The Kailh Box V2 Red is rated for At least 80 M cycles. Lifespan ratings are lab-cycle estimates, so real-world durability can also depend on build quality and usage.
The Kailh Box V2 Red lists top housing: PC, bottom housing: Nylon, stem: POM, contact: Composite gold. These parts influence feel, sound, wobble, and long-term switch consistency.
