4-Piece custom mechanical keyboard switch bottom housing kit for linear mute switches

This kit provides the essential bottom housing components for enthusiasts looking to modify or build a custom mechanical keyboard with a specific typing sound and feel. Designed around the 'small window candle cutting' aesthetic, these parts are more than cosmetic; they integrate specialised damping materials and a unique structure intended to create a linear, muted keypress. The 4-piece format allows for targeted upgrades to frequently used keys or for testing in a build before committing to a full set. Each component is manufactured to precise specifications to ensure consistent performance across the switches you assemble.

Features and Construction

This switch bottom housing is defined by its material composition and internal design, which directly influence the keyboard's acoustics and tactile feedback. The construction prioritises a stable keypress with reduced noise, achieved through a combination of engineered polymers and damping gels.

Material and Build

The core structure uses a PA (Nylon) bottom shell that has been modified with a GF C5 compound, a formulation intended to enhance certain physical characteristics of the base material. The shaft core itself is a two-part assembly: a body made from low-friction POM and an integrated pad of custom-formulated soft silicone gel specifically designed for sound dampening. The upper cover of the complete switch assembly is made from POK polymer, a material selected for its impact resistance and durability in mechanical applications.

Size and Practical Fit

The housing is designed to work with a standard MX-style switch footprint, making it compatible with many custom mechanical keyboards. The key mechanical specifications include a trigger (actuation) point at 1.9mm of travel and a full bottom-out distance of 3.7mm. These housings are intended to be used with a 16mm long, single-section spring (XC55 specification) which contributes to the defined actuation force of 38g and a bottom-out force of 55g.

Uses and Placement

These components are central to the DIY custom keyboard community, where individual switch feel and sound are highly personalised. They are not a complete switch but a fundamental part that determines housing stability and sound profile.

Event or Professional Use

For keyboard meet-ups, competitive gaming, or office environments where keyboard noise is a concern, modifying switches with these muted bottom housings can create a more acoustically pleasant experience. The linear action and dampened sound profile aim to provide consistency and reduce auditory distraction during prolonged use.

Everyday Home Use

At home, these allow an enthusiast to build a keyboard that suits their personal preference for a quieter, smooth keypress without the tactile bump of other switch types. The 4-piece kit is ideal for modifying the primary gaming keys (WASD) or the spacebar enter keys, which are often the focus of custom sound dampening projects.

Benefits and Buying Value

The value lies in the ability to precisely alter the foundation of your keyboard's switches, a level of modification that pre-built keyboards do not offer. It provides a targeted upgrade path.

Reuse and Low Maintenance

As a structural component, the bottom housing is not subject to wear in the same way as moving parts like springs or stems. Once installed in a soldered or hot-swap keyboard, it requires no maintenance. The materials selected, like POK and modified PA, are chosen for their long-term stability in a mechanical assembly.

Why Choose This Product

Choose this kit if you require specific bottom housings to complete a custom switch build focusing on a linear, muted sound signature. The inclusion of specialised Japanese silencing oil lubrication and a silicone-damped core offers a pre-configured path to a quieter switch, saving time compared to sourcing and combining these elements separately. It is a component for builders who pay attention to every detail of switch acoustics.
