This linear mechanical switch is aimed at users who prefer a deep, smooth keystroke with a distinct thock sound. It is an excellent choice for gamers and prolific typists seeking a longer travel distance and a firmer bottom-out feel. The switch comes factory-lubed for smoother operation and is designed to provide a refined typing experience with drastically reduced scratchiness compared to earlier models.
Feel and Sound
Deep Thock Profile: Offers a deep and rich (thocky) sound profile that makes each press feel solid, without any tactile feedback.
Exceptional Smoothness: The switch is smoother than many alternative models thanks to comprehensive factory lubrication on the stem legs, spring, and housing rails, which effectively eliminates scratchiness.
Deliberate Bottom-Out: The longer total travel of approximately 4.0 mm creates a more decisive press feel and a firmer, stable landing at the bottom.
Actuation and Characteristics
Balanced Pressure: An operating force of approximately 45g provides moderate resistance, perfectly suitable for both typing and gaming.
Focus on Accuracy: A pre-travel of 2.0 mm means the key registers after a relatively deep initial press, prioritizing software accuracy over ultra-high speed.
Tangible Finish: The force at full bottom-out is close to 53g, adding tangible feedback at the end of the stroke – a sensation some users find highly satisfying, while others find it fatiguing during prolonged work.
Build Quality
Specialized Materials for Deep Sound: The use of a T5 stem and P4 bottom housing ensures a deeper sound and a more solid physical feel.
Polycarbonate Top: The top housing is made of polycarbonate (PC), which further contributes to the smoothness and specific acoustic characteristics of the model.
Precise KOS Spring: Equipped with a 22mm single-stage extended KOS spring, which perfectly balances force distribution and travel length.
