Introduction: The Kailh Magnetic Switch Family — Which One Is Right for You?

If you’ve been shopping for a Hall effect keyboard, chances are you’ve come across the name Kailh more than once. As one of China’s most established switch manufacturers, Kailh has built a serious reputation in the mechanical keyboard world — and now they’ve brought that same engineering pedigree into the fast-growing magnetic switch category.

The result is a lineup that covers nearly every use case a keyboard enthusiast could ask for. From the competition-ready Purple Flame and the rock-solid Magnetic God, to the visually stunning Jellyfish and the whisper-quiet Silent series, Kailh’s magnetic switch family spans esports, RGB showpieces, and silent office setups alike.

In this guide, we’ll break down all four switches across four key dimensions — force curve, travel data, feel, and ideal use case — so you can confidently find the one that fits your needs.

Part 1: Kailh Purple Flame — The Esports Performance Benchmark

The purple Flame is Kailh’s flagship for competitive gamers. Every design choice here points toward one goal: maximum responsiveness with a light, effortless feel.

Core Specifications

• Structure: PC clear top housing + POK stem (self-lubricating) + PA66 nylon bottom + 20mm stainless steel spring + N52 permanent magnet
• Initial force: 35gf
• Total travel: 3.5 ± 0.2mm
• Mechanical lifespan: ≥100 million actuations
• Rapid Trigger precision: 0.01mm
• Magnetic flux (1.2mm PCB): 100 ± 15Gs initial, 640 ± 40Gs bottom-out

Feel & Characteristics

• Light and smooth: The 35gf initial force feels featherlight, and the self-lubricating POK stem keeps every press buttery smooth.
• Wall-stabilized stem: A traditional dual-sidewall design delivers excellent key stability with minimal wobble.
• HiFi acoustics: An eight-rib base structure tunes the sound profile into something notably crisp and refined.
• Strong magnetic actuation: Clear, decisive feedback helps prevent accidental key presses.

Who It’s For

• FPS competitors chasing the fastest possible Rapid Trigger response
• Users who need 0.01mm precision for fine-tuned actuation
• Anyone who loves a light, linear typing experience

Part 2: Kailh Magnetic God — Built for Precision and Stability

Where the Purple Flame chases speed, the Magnetic God chases consistency. This is the switch for players who never want to see a dropped input, even at the most extreme settings.

Core Specifications

• Adjustable actuation: 0.1–3.4mm
• Rapid Trigger precision: 0.01mm
• Total travel: 3.5mm
• Actuation force: ~35gf
• Mechanical lifespan: 100 million clicks

Feel & Characteristics

• Wall-stabilized, sealed-bottom stem: Engineered for what Kailh describes as “stable 0.01mm with zero missed actuations.”
• Clean linear feel: A textbook linear magnetic profile with crisp, decisive triggering.
• Reliability under stress: In testing, even pushing the switch to its absolute limits produced no signal dropouts.

Who It’s For

• Gamers who prioritize stability above all — no dropped inputs, ever
• Users pairing high-performance boards (think 8K polling rate and 128K scan rate)
• Enthusiasts with the budget for a top-tier, no-compromise setup

Part 3: Kailh Jellyfish — Where Looks Meet Feel

The Jellyfish proves that magnetic switches don’t have to choose between beauty and performance. Inspired by bioluminescent deep-sea jellyfish, it’s designed to make RGB lighting shine while still delivering a smooth, versatile typing experience.

Core Specifications

• Structure: POK stem + fully transparent PC top housing + PA12 nylon bottom
• Initial force: 35 ± 5gf
• Total travel: 3.5 ± 0.2mm
• Mechanical lifespan: 100 million actuations
• Rapid Trigger precision: 0.01mm
• Magnetic flux (1.2mm PCB): 100 ± 15Gs initial, 640 ± 40Gs bottom-out

Feel & Characteristics

• Fully transparent design: The clear PC housing lets RGB lighting glow through beautifully.
• Optimized smoothness: An octagonal base hole plus a raised circular platform at the bottom keep presses gliding.
• 20mm long spring: Delivers a crisp, snappy return.
• Sound signature: A gentle, non-harsh “clicky” tone that’s pleasant rather than piercing.

Who It’s For

• RGB lighting enthusiasts who want their board to glow at its brightest
• Users who split time between gaming and everyday typing — the 35gf force suits both
• Anyone who values a great-looking switch as much as a great-feeling one

Part 4: Kailh Silent Series — Quiet Offices and Late-Night Gaming

Not every setup calls for clicky feedback. The Silent series (using the Midnight Pro Silent as our reference) is built for shared spaces where noise simply isn’t an option.

Core Specifications

• Actuation force: 45 ± 10gf
• Pre-travel: 1.9 ± 0.4mm
• Total travel: 4.0 ± 0.4mm
• Noise level: Silent (≤25–30dB)
• Mechanical lifespan: ≥70 million actuations

Feel & Characteristics

• Genuinely silent: Noise levels around 30dB — far quieter than standard mechanical switches.
• Linear or tactile options: Available in both silent linear and silent tactile versions.
• Crisp return: A return force of ≥15gf keeps the feel snappy rather than mushy.

Who It’s For

• Office and dorm users who need to keep the peace
• Late-night gamers who don’t want to wake the household
• Users who want a deeper 4.0mm travel for a more substantial keypress

Part 5: Side-by-Side Comparison Table

Here’s how all four switches stack up at a glance:

Dimension	Purple Flame	Magnetic God	Jellyfish	Silent Series
Initial Force	35gf	~35gf	35 ± 5gf	45 ± 10gf
Total Travel	3.5 ± 0.2mm	3.5mm	3.5 ± 0.2mm	4.0 ± 0.4mm
RT Precision	0.01mm	0.01mm	0.01mm	—
Lifespan	≥100M	100M	100M	≥70M
Key Selling Point	POK self-lube stem, HiFi sound	Wall-stabilized, zero dropouts	Full transparency, RGB	Ultra-quiet (≤30dB)
Best For	Competitive FPS	High-perf gaming	RGB display, daily use	Office, dorm, late night
Feel Type	Light linear	Stable linear	Smooth linear	Silent linear/tactile

The takeaway: three switches lean toward performance and aesthetics, while the Silent series carves out its own niche for quiet environments.

Part 6: Buying Guide — Find Your Match in One Glance

The easiest way to choose is to start with how and where you’ll use your keyboard.

By Use Case

• I’m an FPS competitor chasing peak responsiveness → Purple Flame (0.01mm RT precision + 35gf light feel)
• I want maximum stability with zero missed inputs → Magnetic God (wall-stabilized stem, rock-solid 0.01mm)
• I’m an RGB lover and want a gorgeous board → Jellyfish (full transparency, lighting maxed out)
• I’m in an office or dorm and can’t disturb others → Silent series (≤30dB quiet performance)

By Feel Preference

• Light and smooth: Purple Flame ≈ Jellyfish > Magnetic God > Silent
• Stable and solid: Magnetic God > Purple Flame > Jellyfish > Silent
• Silent operation: Silent series (the only choice)

On Budget

As an established manufacturer, Kailh typically prices its premium models 15–20% higher than competitors — but that premium buys better structural stability and more refined factory tuning.

• Value-focused entry points: Jellyfish and Purple Flame offer the best bang for your buck.
• No-compromise top tier: Magnetic God is the one to beat.

Conclusion: There’s No “Best” — Only the “Best Fit”

Each of these four Kailh magnetic switches plays to a different strength, and that’s exactly the point. There’s no single winner here — just the switch that fits your setup best.

• Purple Flame → competitive performance
• Magnetic God → uncompromising stability
• Jellyfish → looks and lighting
• Silent → quiet comfort

The smartest approach is to weigh your use case, feel preference, and budget together. Match those three, and you’ll land on the Kailh switch that feels like it was made for you.
