Dew Axis-4 mechanical keyboard switch bottom casing with three-colour POM and silicone core for custom keyboard building

This mechanical keyboard switch bottom casing provides the essential foundation for assembling custom keyboards with specific performance characteristics and aesthetic preferences. Available in the Dew Axis-4 colour finish, these casings incorporate several design elements aimed at improving the typing experience through reduced noise and consistent actuation. The product represents a specialised component for keyboard enthusiasts seeking to modify or build mechanical keyboards with particular attention to switch performance and sound characteristics. Each element from the bridge plug-in structure to the proprietary spring system contributes to a complete solution for custom keyboard construction.

Features and Construction

The switch bottom casing integrates multiple construction elements designed for both functionality and compatibility within mechanical keyboard systems. The bridge plug-in structure with large side buckles ensures secure installation while maintaining proper alignment within standard switch housings. This physical design allows for straightforward assembly while providing reliable mechanical connections between switch components. The construction approach balances accessibility for custom builders with the precision required for consistent keyboard performance across multiple keys.

Material and Build

Material selection focuses on specific performance characteristics within the switch assembly. The upper cover utilises POK polymer raw materials chosen for their structural properties, while the bottom casing combines PA material with GF C5 modification for enhanced durability. The three-colour shaft core represents a notable construction element, combining POM material for the shaft body with customised soft silicone gel integrated to dampen sound during keypresses. Japanese silencing oil replaces standard grease lubrication at the spring bottom, offering a specialised approach to reducing friction-related noise.

Size and Practical Fit

Trigger and travel specifications follow mechanical keyboard industry standards while offering specific performance parameters. With a trigger travel distance of 1.9mm ±0.3mm and bottom-out travel of 3.7mm ±0.3mm, the switch provides predictable keypress behaviour. Pressure specifications include 38g ±5g trigger pressure, 44g ±5g actuation excitation, and 55g ±5g bottom-out pressure, creating a tactile profile suited to both typing and gaming applications. The exclusive XC55 16mm single-section spring contributes to consistent pressure application throughout the keypress cycle.

Uses and Placement

As a component rather than a complete product, these switch bottom casings serve specific purposes within keyboard customisation and building projects. The product addresses needs for both modification of existing mechanical keyboards and construction of entirely custom keyboard assemblies. With four pieces included per package, the casings provide sufficient quantity for typical keyboard modification projects while allowing builders to assess performance before committing to larger quantities. The design supports both aesthetic customisation through the Dew Axis-4 colour and functional improvement through its specialised construction elements.

Event or Professional Use

For professional environments or events where keyboard noise reduction benefits multiple users, these switch components offer practical solutions. The combination of silicone-gel dampening in the shaft core with Japanese silencing oil lubrication addresses common sources of mechanical keyboard noise. Professionals working in shared office spaces, recording environments, or streaming setups can benefit from reduced keyboard sounds without sacrificing the tactile feedback characteristic of mechanical switches. The specified pressure parameters support both extended typing sessions and precise gaming inputs where consistent response matters.

Everyday Home Use

Home users building custom keyboards for personal workspaces will appreciate the balance of aesthetic and functional elements. The Dew Axis-4 colour finish offers visual distinction while the bridge plug-in structure simplifies the assembly process for custom builders. Everyday typing experiences benefit from the predictable travel distances and pressure specifications, which provide sufficient tactile feedback without excessive force requirements. The four-piece package allows home users to test the components in specific keyboard positions before committing to full keyboard conversions.

Benefits and Buying Value

The switch bottom casings deliver value through their specialised construction approach and compatibility with standard mechanical keyboard components. Rather than offering a complete switch solution, these components provide specific improvements to existing switch designs while maintaining compatibility with common keyboard layouts and housings. Buyers seeking to modify keyboard sound profiles or improve consistency across multiple switches will find the combination of materials and specifications addresses common customization needs. The product serves as an intermediate component between basic switch options and fully customised switch assemblies.

Reuse and Low Maintenance

The construction materials support repeated use with minimal maintenance requirements. The POK polymer upper cover and modified PA bottom casing materials maintain their properties through extended use cycles, while the integrated silicone gel in the shaft core retains its damping characteristics without requiring replacement. Japanese silencing oil lubrication at the spring bottom provides longer-lasting performance compared to standard grease applications. These elements combine to create switch components suitable for keyboards intended for long-term use without frequent maintenance or component replacement.

Why Choose This Product

This product suits keyboard builders seeking specific improvements to switch performance rather than complete switch assemblies. The combination of three-colour shaft core with silicone damping, specialised lubrication, and precise pressure specifications addresses multiple aspects of switch performance simultaneously. Buyers interested in reducing keyboard noise while maintaining mechanical switch characteristics will find the product's approach balances these sometimes competing priorities. The bridge plug-in structure ensures compatibility with existing switch housings, making the components accessible to builders with various skill levels.
