Custom Linear Silent Mechanical Keyboard Switch Bottoms with Japanese Silencing Oil

Upgrade your custom mechanical keyboard build with these specialised linear silent switch bottoms. This 4-piece set is engineered for users seeking a quiet, smooth keystroke with precise actuation. Each component is designed around a core principle of noise reduction, employing a unique Japanese silencing oil and a multi-material construction to dampen sound without sacrificing tactile consistency. The Dew Axis-4 colourway offers visual distinction, while the detailed technical specifications provide the exacting data required for informed keyboard assembly and performance tuning.

Features and Construction

The switch bottoms are defined by their focused approach to silent linear operation and robust construction. Every material and specification is chosen to contribute to a consistent, muted keypress feel suitable for office environments, shared spaces, or personal preference.

Material and Build

The shaft body construction utilises several advanced polymers for performance. The upper cover is moulded from POK polymer raw material, while the main bottom shell is a composite of PA (Polyamide) reinforced with a significant amount of GF C5. This combination aims for structural integrity. Internally, the heart of the switch is a three-colour shaft core, where a POM (Polyoxymethylene) body is paired with a custom-formulated soft and silent silicone gel, working in tandem to cushion the keystroke.

Size and Practical Fit

These components are the 'shaft bottom' part of a mechanical keyboard switch, designed to be installed into a keyboard's plate and housing. The outer shell uses a bridge plug-in structure with large buckles on both sides, intended to secure the switch firmly within the keyboard assembly. The physical dimensions are precisely defined: the actuation point is reached at 1.9mm of travel, with a tolerance of ±0.3mm, and the key bottoms out after a total travel of 3.7mm, also with a ±0.3mm tolerance.

Uses and Placement

These switch bottoms are tailored for specific keyboard-building scenarios where control over sound and feel is paramount. They are not standalone switches but key internal components for a custom build.

Event or Professional Use

For streamers, content creators, or professionals in open-plan offices, the primary silenced operation is a direct benefit. The replacement of standard grease lubrication with a special Japanese silencing oil at the spring's base is a targeted modification to reduce spring ping and mechanical noise. This makes them a consideration for builds where microphone clarity or ambient noise reduction is a priority.

Everyday Home Use

For the home enthusiast or daily typist, these switches offer a path to a personalised typing experience. The linear action—devoid of a tactile bump or audible click—combined with the silencing elements, can provide a quiet, consistent feel for long typing or gaming sessions. The precise 38g actuation force, provided by the exclusive XC55 16mm single-section spring, offers a light touch that may reduce finger fatigue.

Benefits and Buying Value

The value of these components lies in their specialised materials and specified performance, offering a clear alternative to standard, unmodified switches for the custom keyboard builder.

Reuse and Low Maintenance

As durable mechanical components made from engineering plastics like POM, POK, and reinforced PA, they are built for long-term use within a keyboard. The design does not require end-user maintenance; the factory-applied Japanese silencing oil and integrated silicone gel are intended to perform consistently over the switch's lifespan without need for re-lubrication.

Why Choose This Product

Choosing this product means selecting a component set focused on a specific outcome: a quiet, linear keypress. The differentiators are concrete: the custom Japanese silencing oil, the three-material shaft core with silicone gel, and the precisely documented force curve (38g actuation, 44g trigger, 55g bottom-out). For builders who value these specific technical attributes and the Dew Axis-4 colour, this 4-piece pack provides the exact parts to execute that vision.
