HMX Citrus Silver V2 Linear Switches

The HMX Citrus Silver V2 Linear is a speed-focused mechanical switch designed for users who prioritize fast key activation and a smooth keystroke. It suits gamers and typists seeking quick response times with a linear feel and a sound profile that differs from typical magnetic switches. This switch emphasizes rapid actuation with a short pre-travel and total travel distance, making it less ideal for those who prefer tactile feedback or quieter operation.

Actuation Characteristics

• Extremely short pre-travel of 1.0mm enables fast key registration, reducing input delay.
• Total travel of approximately 3.0mm is slightly shorter than standard switches, supporting quicker resets.
• Operating force around 45g provides a light but consistent press, balancing speed and control.
• Bottom-out force near 50g offers a defined end-point without harsh impact, aiding in comfortable rapid typing.

Feel & Sound

• Linear design delivers smooth keystrokes without tactile bumps, suitable for users who prefer uninterrupted key travel.
• Factory lubrication reduces friction, resulting in quieter operation and a smoother sound compared to many unlubed linear switches.
• Sound profile is distinct from common magnetic switches, offering a cleaner, less metallic tone.

Build Quality

• Stem made from POM (polyoxymethylene) reduces friction for smooth keypresses.
• Top housing is polycarbonate (PC), providing durability and consistent acoustics.
• Bottom housing uses PA66 nylon, contributing to structural stability.
• Spring is a 22mm KOS single-stage extended type, designed for consistent force throughout the keypress.

Modification Potential

• Factory lubed with thin coats of 205g0 on stem legs and sliders, plus dry film on spring and leaf, minimizing initial scratchiness and spring noise.
• Additional lubing may further reduce friction but could alter the intended sound and feel.

Trade-offs

• Short pre-travel and total travel favor speed but may reduce typing accuracy for some users.
• Linear feel lacks tactile feedback, which may be less satisfying for users who prefer a bump or click.
• Unknown compatibility details such as PCB or plate mount type and LED support.
