OVERVIEW

The KD400 is the latest evolution of the 80Retros x HMX switch series, developed as a louder and more energetic continuation of the KD200.

With 45gf actuation force and a 35-piece pack, this linear switch is designed for enthusiasts and everyday users alike.

KEY FEATURES

Next-Generation HMX M1 Hybrid Stem

The KD400 introduces HMX's newly developed M1 hybrid stem material, designed specifically for this switch's updated material combination. Working together with the Modified PA12 top housing and N3 bottom housing, the M1 stem contributes to the KD400's energetic and pronounced acoustic character.

Exceptionally Clacky & Loud Sound Profile

The KD400 is engineered to deliver a significant increase in both clackiness and overall volume compared with the KD200. Its carefully selected combination of housing and stem materials produces what 80Retros describes as the most clacky and loud sound signature in its lineup to date, making it an excellent choice for users who want their keyboard to sound bold and energetic.

PBT + PA66 Composite N3 Bottom Housing

The bottom housing uses a PBT + PA66 composite material known as N3. This material combination plays a key role in shaping the KD400's powerful acoustic profile, helping produce a louder and more pronounced sound when each key is pressed.

Modified PA12 Top Housing

A Modified PA12 top housing complements the KD400's M1 stem and N3 bottom housing. The carefully selected material combination is designed to enhance the switch's acoustic output and contribute to its distinctive clacky character.

45gf Actuation Force

The KD400 is offered with a 45gf actuation force, providing a balanced resistance suitable for both mechanical keyboard enthusiasts and everyday users. This force offers a responsive linear feel without requiring excessive pressure during repeated keystrokes.

Linear Switch Design

As a linear switch, the KD400 provides a smooth, uninterrupted keypress without a tactile bump or click mechanism. Combined with its energetic sound profile, it offers a straightforward typing experience suited to users who prefer smooth key travel and a pronounced acoustic character.

35-Piece Pack

Each pack contains 35 KD400 switches, providing enough switches for smaller keyboards, replacement switches, testing, or selective customization across a larger board.
