HMX Sunset Gleam DuckDuck Switches

The HMX Sunset Gleam DuckDuck is a high-performance linear mechanical keyboard switch designed for enthusiasts seeking a refined typing experience. With carefully engineered materials and thoughtful modifications, this switch delivers a solid and satisfying sound profile while maintaining smooth actuation.

Design and Construction

This switch features a unique combination of materials and engineering enhancements to optimize both sound and feel. The top housing is crafted from polycarbonate (PC), but unlike conventional PC housings, it has been modified at the stem contact point. This adjustment concentrates and solidifies the top-out sound, eliminating the friable and loose acoustic qualities often found in standard PC housings.

The bottom housing is made from modified PA66 with a measured amount of fiberglass. This blend is specifically chosen to create a solid bottom-out sound that is firm but not overly harsh or clacky. The LY stem further enhances the acoustics, resulting in keystrokes that are both solid and pleasantly clacky.

Key Features

• Linear switch type for smooth, uninterrupted keystrokes
• Actuation force: 42±5g
• Bottom-out force: 48±5g
• Pre-travel distance: 2mm
• Total travel distance: 3.5mm
• Factory lubed with a mix of GPL105 and GPL205 on leaf spring, stem feet, and bottom housing rails
• Dry film lubrication applied to springs
• PCB mount (5-pin) for secure installation
• 22mm single-stage KOS stainless steel extended spring for consistent performance

Sound and Typing Experience

The modifications to the top and bottom housings result in a concentrated, solid top-out sound and a firm, non-harsh bottom-out. The LY stem complements these features by producing a keystroke that is both acoustically pleasing and tactilely satisfying. Each press feels stable and consistent, making it suitable for both gaming and typing.

Factory Lubrication

Each switch is factory lubricated for optimal smoothness and reduced friction. The combination of GPL105 and GPL205 lubricants is applied to critical areas, including the leaf spring, stem feet, and bottom housing rails. Additionally, the springs are treated with a dry film lube, ensuring a quiet and smooth operation right out of the box.
