Custom mechanical keyboard switch linear mute Dew Axis-4 bottom-out switch four-piece pack designed with Japanese silencing oil lubrication and a three-colour POM shaft core for silent linear typing feel
Dew Axis-4 Linear Mute Keyboard Switches: Four-Pack for Custom Mechanical Keyboards

Upgrading a mechanical keyboard with custom switches allows for a personalised typing experience tailored to sound, feel, and performance. The Dew Axis-4 linear mute switches are engineered for users seeking a significantly quieter operation without sacrificing the smooth, consistent press of a linear switch. This four-piece pack provides the essential components—the switch bottoms—for a modification project, featuring a construction focused on sound dampening through material choice and specialised lubrication. The design incorporates a three-colour shaft core and a bridge plug-in structure, aiming for reliable performance in office settings, gaming sessions, or any environment where reduced keyboard noise is a priority.
Features and Construction

The Dew Axis-4 switches are built around a linear, non-tactile mechanism, meaning the keypress is smooth from top to bottom without a noticeable bump. Their primary design goal is noise reduction, achieved through several specific construction choices detailed in the source specifications.
Material and Build
The shaft core is a central component, constructed from a POM (Polyoxymethylene) body combined with a custom-formulated soft and silent silicone gel. This combination aims to absorb vibrations and reduce the sound produced during actuation and bottoming out. The upper cover of the switch is made from POK polymer raw materials, selected for its durability and stable properties. The bottom shell uses PA (Polyamide) as its main body, reinforced with a significant amount of a GF C5 improved compound to enhance its structural characteristics and longevity.
Size and Practical Fit
Each switch has precise mechanical dimensions. The actuation point, where a keypress is registered, is set at 1.9mm with a tolerance of ±0.3mm. The total travel distance until the switch fully bottoms out is 3.7mm ±0.3mm. The included spring is a 16mm long, single-section XC55 spring, which contributes to the switch's force curve. The switch body itself uses a bridge plug-in structure with large buckles on both sides, which should ensure a secure fit when installed into a compatible keyboard printed circuit board (PCB).
Uses and Placement

These switches are designed for integration into custom mechanical keyboards. Their performance profile makes them suitable for specific user scenarios where their linear and mute characteristics are most beneficial.
Event or Professional Use
In professional environments like open-plan offices, recording studios, or libraries, excessive keyboard noise can be distracting or disruptive. The Dew Axis-4's mute design, leveraging silicone gel and specialised lubrication, directly addresses this by minimising the audible click and clack of standard mechanical switches. Their linear feel also allows for rapid, consistent typing, which can be advantageous for data entry, coding, or prolonged writing sessions where fatigue from tactile feedback is undesirable.
Everyday Home Use
For home users, these switches offer a way to enjoy the longevity and customisability of a mechanical keyboard without the typically associated noise level. They are a practical choice for shared living spaces, evening gaming, or streaming where microphone pickup of keyboard sounds is a concern. The provided four-piece pack allows users to replace key switches on frequently used keys (like WASD or spacebar) or to test the switches before committing to a full board build.
Benefits and Buying Value

The value of these switches lies in their specific, source-supported technical approach to creating a quiet linear switch, rather than generic claims of quality.
Reuse and Low Maintenance
Mechanical keyboard switches are generally rated for tens of millions of keystrokes, and the material choices here—POM, POK, and reinforced PA—are selected for wear resistance. The use of a specialised Japanese silencing oil lubrication at the bottom of the spring, as opposed to standard grease, is intended to maintain its sound-dampening properties over time without drying out or degrading quickly, which could contribute to a longer consistent feel.
Why Choose This Product
Choosing the Dew Axis-4 switches is a decision based on concrete specifications. The combination of a POM and silicone gel core, precise actuation forces (38g actuation, 55g bottom-out), and the unique silencing oil lubrication differentiates it from standard linear switches. For the custom keyboard builder, this pack offers a chance to implement a switch designed with a clear focus on muting sound through material science and precise lubrication, backed by the stated mechanical measurements of travel and force.
