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.
✨ Longhua Lime HE: The absolute esports solution featuring micro-precision 0.01mm RT, self-lubricating POK rails, and a highly translucent design.
Instantly Freeze Movement
0.01mm Rapid Trigger Dynamic Control
The Solution
Leverages high-specification N52H NdFeB Neodymium permanent magnets paired with ultra-sensitive contactless Hall effect sensors to track continuous key position dynamically.
The Benefit
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
The Solution
Adopts premium optical-grade translucent Polycarbonate (PC) for the top housing, creating a highly polished, fully unobstructed optical channel above your SMD LEDs.
The Benefit
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
The Solution
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.
The Benefit
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."
— @RT_Wizard, Radiant Rank
★★★★★
"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."
— @ApexPred, Hardcore Gamer
★★★★★
"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!"

These are linear Hall Effect (HE) magnetic switches featuring a North-Pole-Down (NPD) polarity orientation. They are exclusively compatible with magnetic HE hot-swap keyboard PCBs that support NPD switches (such as Apex Pro, Wooting, and similar custom magnetic boards). They will not work on traditional mechanical PCBs or optical keyboards.
Yes, absolutely. In top-tier competitive games like CS2 or Valorant, micro-movements require immediate changes in key depth. Having an incredibly fine 0.01mm RT resolution allows your keyboard sensor to process your exact release-velocity without lagging behind, giving you an undisputed physical advantage on critical counter-strafes.
POK (Polyketone) material is a next-generation polymer offering a significantly lower friction coefficient and up to three times the wear-resistance of standard POM. This means it slides flawlessly with zero sandy resistance, reduces stem wobble, and self-lubricates continuously, getting smoother the more you use it.
No manual lubing is required. To maintain peak electromagnetic performance, the switches are pre-lubericated during production using advanced, high-precision automated spray systems. Manual lubrication runs the risk of fluid leakage onto the magnet and PCB, which can lead to sensor failure or magnetic flux degradation.
