Tired of Scratchy Linears and Hollow Sound?
Muddy, Inconsistent Acoustics
Many linear switches produce spring ping, scratch, or a hollow “clack” that ruins the typing experience.
Sluggish Rebound, Finger Fatigue
Standard springs often feel slow or heavy, making rapid typing or gaming less responsive.
Wobble & Short Lifespan
Cheaper materials lead to stem wobble and premature wear, forcing early replacement.
🐎 Black Horse – The Workhorse Linear — Dupont POM stem + PA66 housing deliver studio‑grade “thock”; 20mm spring provides snappy, fatigue‑free rebound; 70M cycle rating ensures years of reliable performance.
Why Black Horse?
🧪 Dupont POM Stem
🏗️ PA66 Reinforced Housing
🎵 Deep "Thock" Sound
🔇 Zero Scratch / Ping
🎧 HiFi Linear Architecture
POM Stem + PA66 Housing – Pure Acoustics, Industrial Strength
🔹 Feature Dupont POM stem (self‑lubricating) paired with reinforced PA66 top and bottom housing. Engineered to dampen unwanted frequencies while enhancing the fundamental “thock.”
🔹 Advantage Zero scratch, zero spring ping – just a clean, deep, satisfying keystroke sound. PA66 adds structural rigidity, reducing stem wobble and improving long‑term consistency.
🔹 Benefit Enjoy a premium typing experience straight out of the box. The sound profile is rich yet unobtrusive, perfect for both focused work and immersive gaming.
🔹 Evidence Lab tests show PA66 housing reduces internal resonance by 30% compared to standard nylon; community reviews consistently praise the “studio‑grade thock.”
⚡ 45gf Actuation · 20mm Extended Spring · 2.0mm Pre‑travel
Snappy rebound, fatigue‑free, intentional feel⚡ Responsive Yet Controlled
Light Enough for Speed, Substantial Enough for Precision
🔹 Feature 45±5gf operating force with a 20mm extended spring. Pre‑travel of 2.0mm gives just enough distance to avoid accidental presses while still feeling immediate.
🔹 Advantage The extended spring delivers snappy, consistent rebound – ideal for rapid key spamming in games or high‑speed typing. The 45gf weight strikes the perfect balance between lightness and feedback.
🔹 Benefit All‑day comfort without finger fatigue, plus the confidence that every press is intentional. Works equally well for office work, programming, and competitive gaming.
🔹 Evidence Kailh force curve testing confirms a smooth, linear progression with a crisp bottom‑out. User feedback: “fast enough for gaming, substantial enough to feel premium.”
🔋 Endurance & Smoothness
Out‑of‑Box Smoothness That Lasts for Years
🔹 Feature Each switch receives a precise factory lube application on the stem rails and spring. Gold‑plated contacts and durable PA66/POM materials ensure exceptional longevity.
🔹 Advantage No need to hand‑lube unless you want a custom sound profile. The switches are smooth from day one and maintain that smoothness over 70 million cycles.
🔹 Benefit Spend less time modding and more time enjoying your keyboard. The Black Horse is a true “install and forget” workhorse that will outlast multiple keyboards.
🔹 Evidence Kailh reliability testing: 70 million actuations with less than 5% force degradation. Gold contacts prevent oxidation, ensuring consistent electrical performance.

❓ Frequently Asked Questions
What makes the Black Horse sound different from other linears?▼
The combination of Dupont POM stem and reinforced PA66 housing is specifically tuned for acoustic performance. PA66 dampens high‑frequency noise (spring ping, scratch), while the POM stem produces a clean, deep “thock” on bottom‑out. It’s often compared to high‑end custom switches but comes factory‑lubed and ready to use.
Is the 45gf force too light for gaming?▼
45gf is widely considered the sweet spot for both gaming and typing. It’s light enough for rapid inputs and long sessions without fatigue, but still substantial enough to prevent accidental presses. The 2.0mm pre‑travel adds intentionality, so you won’t trigger keys unintentionally during intense gaming.
Do I need to lube these switches?▼
No. They come with factory lubrication on the stem rails and spring. Most users find them perfectly smooth out of the box. If you’re an enthusiast who wants a specific sound signature, you can add additional lube, but it’s completely optional.
Will these work with my 3‑pin hot‑swap board?▼
Yes. The Black Horse is a 5‑pin switch (2 metal pins + 3 plastic positioning pins). The two extra plastic pins can be clipped off with flush cutters to fit 3‑pin PCBs without any issue.
How does the 20mm spring affect the feel?▼
A longer spring provides a more linear force curve and snappier return. It makes rapid double‑taps feel more responsive and reduces finger fatigue compared to shorter, stiffer springs. The 20mm design is a hallmark of premium linear switches.
What’s the expected lifespan?▼
The Black Horse is rated for 70 million keystrokes. The gold‑plated contacts resist corrosion, and the PA66/POM materials are highly durable. Under normal use, these switches will outlast multiple keyboards.
