Kailh Longhua Lime HE Switch

Kailh Longhua Lime HE Switch
The Game-Changing "Physical Cheat Code": 0.01mm Ultra-Precise RT Response & 35gf Feather Actuation.
Are you tired of sluggish traditional mechanical switches causing you to lose crucial counter-strafing duels in FPS games? Or perhaps you're exhausted by mushy magnetic switches that suffer from signal drift and muddy, wobbly travel? Engineered by the legendary switch masters at Kailh, the Longhua Lime Magnetic Switch is your ultimate upgrade.
Equipped with a contactless Hall Effect sensor and an industry-leading N52H NdFeB Neodymium permanent magnet, it supports an incredibly micro-adjustable 0.01mm Rapid Trigger (RT) step precision. Coupled with a feather-light 35gf actuation force, self-lubricating POK stem, and an optically clear PC housing, it redefines speed, acoustics, and visual aesthetic on your path to victory.
Core Advantages: Disrupting the Magnetic Switch Experience
We know you demand perfect control. The Longhua Lime is engineered specifically to eliminate the generic magnetic switch issues of coarse accuracy, rough sliding friction, and dull lighting.
The Problem: Coarse Signal Drift
Ordinary magnetic switches suffer from temperature-sensitive drift or use budget magnets, limiting their Rapid Trigger precision to a sluggish 0.1mm - 0.2mm step that fails to register quick counter-strafes.
The Problem: Sandy Scratchiness
Using generic low-grade plastics for both stems and housings introduces dry, scratchy friction. This results in an uneven force profile that ruins muscle memory during intense gaming clutches.
The Problem: Dim, Opaque Housings
Solid plastic bottom housings or standard open slots swallow the keyboard's SMD LED illumination, creating severe dark spots and muting custom RGB backlighting.
Instantly Freeze Movement
0.01mm Rapid Trigger Dynamic Control
Leverages high-specification N52H NdFeB Neodymium permanent magnets paired with ultra-sensitive contactless Hall effect sensors to track continuous key position dynamically.
Enjoy absolute mechanical command. Setting your Rapid Trigger (RT) step to an absurdly precise 0.01mm means the instant your finger lifts—even a fraction of a millimeter—the switch immediately resets, freezing your character on a dime for perfect first-shot accuracy in Valorant and CS2.
Illuminate Your Desk
Optical-Grade 100% High-Transparency PC Top
Adopts premium optical-grade translucent Polycarbonate (PC) for the top housing, creating a highly polished, fully unobstructed optical channel above your SMD LEDs.
Unleash the full potential of your keyboard's custom RGB lighting. It eliminates ugly dark spots and diffuses sharp hot-spots into an incredibly rich, uniform 3D volumetric aura that highlights custom keycap sets beautifully.
Endgame Friction-Free Gliding
35gf Feather Actuation & POK Stem
Combines a feather-light 35gf initial operating force with a self-lubricating POK (Polyketone) material stem sliding within a modified, highly stable PA66 lime-green bottom housing.
Enjoy buttery smooth linear travel with a snappy, fatigue-free rebound. The POK stem is incredibly wear-resistant and naturally self-lubricating, meaning the switch actually feels smoother the more you type. Perfect for hours of ranked grinds without finger joint fatigue.

Customer Reviews
"Rapid Trigger feels like pure wizardry."
"I swapped my old HE switches out for the Longhua Limes and the rapid trigger resolution difference is crazy. Setting my RT to 0.01mm on my board means my movement stops instantly on release. No signal drift at all, and the N52H magnets are unbelievably fast."
"35g weight is a godsend for long grinds."
"I play high-APM games and standard 45g/50g switches make my hand cramp after an hour. The 35g Lime weight feels like walking on air. The POK stem is insanely slick, and there's zero of that sandiness you find on cheap magnetic switches."
"Gorgeous translucent housing."
"The optical high-transparency PC top completely opened up my custom board's RGB. Instead of harsh beams passing through holes, it gives a beautifully soft, diffused look. Looks absolutely incredible combined with pudding keycaps!"
