haimu x YG Studio Mulberry Tactile Switches

This tactile switch is designed for users who want a crisp, noticeable bump during typing. It suits typists who prefer clear tactile feedback without excessive force. The metal insert in the stem and housing sharpens the tactile feel, making it distinct. It is less ideal if you prefer smooth or linear switches or need a very quiet option.

Feel & Sound

• The metal insert creates a sharp, defined tactile bump, enhancing feedback clarity.
• Typing feel is crisp, helping with precise keypress recognition.
• Sound profile is moderately audible due to the metal components, producing a distinct clicky-like sound without an actual click mechanism.

Actuation Characteristics

• Actuation force is moderate, requiring 47g to register a keypress, which balances responsiveness and fatigue.
• Pre-travel of 2mm provides a noticeable distance before the bump, aiding typing accuracy.
• Total travel of 3.6mm gives a standard keypress depth, with a firm bottom-out at 55g.

Build Quality

• Housing is made of polycarbonate (PC), offering durability and consistent sound.
• Stem material is LY, a type of nylon known for smooth movement and stability.
• Spring length is 20mm, contributing to the force curve and bottom-out feel.

Compatibility

• PCB mount with 5-pin design ensures stable installation and compatibility with most PCBs.
• Top and bottom housings are standard PC, compatible with common keycap profiles.

Modification Potential

• Factory lubed, reducing initial scratchiness and improving smoothness out of the box.
• Additional lubing may further reduce noise and smooth the tactile bump, but the crispness might soften.

Trade-offs

• The metal insert can increase switch noise, which may not suit quiet office environments.
• Some users might find the tactile bump too sharp or pronounced for rapid keypresses.
• Unknown break-in period and long-term durability under heavy use.
