Core Advantages: Your Ultimate Portable Linear Choice
We know you love the pure feel of linear switches but despise the bulk of traditional boards and cluttered friction noise. Spring Mini is born to recreate "Ultimate Smoothness" in an ultra-thin footprint.
The Problem: Scratchy Friction
Many low-profile switches use standard plastics with poor or uneven lubrication, causing a "sandpaper" feel that ruins your typing rhythm.
The Problem: Input Lag
Standard high-profile or poorly designed low-profile switches have long pre-travel, making you feel "a beat behind" during rapid typing or gaming.
The Problem: Bulky & Heavy
Traditional mechanical switches are too tall for modern minimalist, travel-friendly thin keyboards and custom Hitbox controllers.
✨ Kailh Spring Mini: The perfect solution offering a self-lubricating POM glide, 1.2mm instant response, and a sleek ultra-thin profile.
Say Goodbye to Scratchiness
POM Self-Lubing: A Fingertip Miracle
The Solution
Constructed with a base made of self-lubricating POM (Polyoxymethylene) material, complemented by Kailh's high-precision automated factory lubing process.
The Benefit
Peak smoothness out of the box that actually evolves over time. POM material has a naturally low friction coefficient; with daily use, it becomes even smoother and more polished. Enjoy a delicate glide that feels like sliding on silk.
Say Goodbye to Input Lag
1.2mm Light-Speed Response
The Solution
Boasts an extreme 1.2mm actuation distance—over 25% faster than standard switches—combined with an ultra-short 2.8mm total travel.
The Benefit
Think it, and it executes. The ultra-short travel drastically increases your typing speed and reduces finger lift height. Whether coding at high speed or reacting in a match, it delivers instantaneous feedback for a truly fluent experience.
Say Goodbye to Bulky Peripherals
Ultra-Thin Design & Premium Visuals
The Solution
Adopts a sleek low-profile structure (Choc V2 pin specs), reducing thickness by 40% compared to standard switches. The high-transparency PC top perfectly accommodates all RGB setups.
The Benefit
Easily build the ultimate lightweight productivity tool. Perfectly compatible with top-tier ultra-thin boards like Lofree Flow and IQUNIX MG65, or custom Hitbox controllers. Zero compromise on smoothness or brilliant aesthetics.

— @SmoothOperator, Custom Keeb Hobbyist
★★★★★
"The developer's long-hour miracle."
"40g is the absolute sweet spot. Lightweight enough that my fingers don't ache after coding all day. Solid bottom-out sound from the POM. Best pairing for my Lofree."

Spring is an ultra-smooth linear switch; Summer is a medium Clicky; Autumn is a light Clicky; and Winter is an Early-Bump Tactile. Spring is perfect for those who love the classic linear feel with minimal resistance.
As long as your keyboard uses the Choc V2 (3-pin) specification, it is perfectly compatible. This includes Lofree Flow, IQUNIX MG65, and most custom Hitbox controllers. It is NOT compatible with standard Cherry MX high-profile PCBs or MX keycaps.
40gf is widely considered the sweet spot for lightweight typing. It is slightly lighter than traditional Red switches (45gf), which helps significantly reduce fatigue while retaining a clear actuation point for rapid input and competitive gaming.
POM (Polyoxymethylene) is highly durable and inherently self-lubricating. A POM base means almost zero friction during the stem's glide. Over time, it creates a natural "wear-in" layer that makes the switch feel even smoother than it did on day one.
