Hall Effect Switches: The Only 'Innovation' You Actually Need
Hall Effect Switches 101. Everything you need to know about magnetic switches: how they work, why they matter, and why they don't work in your PCB.
Let’s be honest: most “innovations” in the keyboard world are just marketing teams finding new ways to sell you the same colorful plastic. But occasionally, physics actually brings something useful to the table. Enter the Hall Effect switch—a technology that predates your parents but has somehow become the hottest thing in gaming because you can’t aim properly.
If you’re still clinging to your Cherry MX Blues thinking they make you a typist, sit down. Class is in session.
It’s Magnets, You Luddite
Contrary to popular belief, “Hall Effect” isn’t a DJ name. It’s a physical principle discovered by Edwin Hall in 1879. Yes, 1879. The fact that it took us this long to put it in a gaming keyboard is a testament to our collective slowness.
Here is the simple version for those of you who failed high school physics:
- The Magnet: There is a magnet in the stem of the switch.
- The Sensor: There is a Hall Effect sensor on the PCB (Printed Circuit Board).
- The Magic: As you press the key, the magnet moves closer to the sensor. The sensor measures the change in magnetic field strength (flux).
That’s it. No metal leaf making contact, no copper oxidization, no friction from bending metal. Just a magnet moving through void space. This means the signal is analog. It’s not just “On” or “Off”; it’s “How far?”
Why You Should Care (Even If You Don’t)
“But Professor,” you whine, “my mechanical switches are fine!”
They are adequate. Hall Effect switches are superior. Here is why:
1. Durability
Because there are no physical contacts to bang against each other, these switches are rated for 100 million presses. You will develop arthritis long before these switches fail.
2. Smoothness
Friction is the enemy. By removing the contact leaf—the part of a mechanical switch that creates friction—Hall Effect switches are inherently smoother. It’s simple mechanics.
3. The “Cheat” Codes: Rapid Trigger
This is why you’re actually here. Because the board knows exactly where the key is, it can reset the actuation point the instant you let go. You don’t have to release the key fully to press it again. This allows for superhuman strafing speeds in games like Valorant or OSU!. It’s basically cheating, but legal.
The Market Landscape: A Brief History of Hype
Wooting started this fire. They are the ones who proved that analog input on a keyboard wasn’t just a gimmick. Everyone else is just playing catch-up.
- Gateron: The primary manufacturer for most HE switches (including Wooting’s “Lekker” switches). If you buy an HE switch, there is a 90% chance it came from Gateron’s factory.
- Geon / Raw: The enthusiast options. Better molds, tighter tolerances, aimed at people who lube their switches on weekends.
- The Clones: Brands like Outemu and TTC are entering the fray, but Gateron remains the gold standard for compatibility.

If you love the tactile bump of a Holy Panda or the ear-piercing shriek of a clicky Blue switch, I have bad news.
Hall Effect is dominated by Linears.
Don’t know what ‘Linear’ means? It means smooth. If you need a crash course on the difference between Linear, Tactile, and Clicky, read our mechanical switch guide.
Switch Types 101Why? Because magnets move smoothly. Introducing a tactile bump or a click leaf introduces friction and inconsistency—the very things HE tries to eliminate.
- Linear: 99% of the market. Smooth, consistent, fast.
- Tactile: They exist (e.g., Gateron Magnetic Jade Tactile), but they are rare and often feel… compromised. The bump fights the analog nature of the switch.
- Clicky: Practically non-existent. If you want a click, buy a typewriter.
Compatibility: Stop Asking This Question
I will say this once, and I will type it slowly:
You. Cannot. Put. These. In. Your. Normal. Keyboard.
“But they fit in the plate!” I don’t care. Your standard mechanical keyboard PCB does not have Hall Effect sensors. It has two metal holes. A magnet does nothing to a metal hole. You need a dedicated Hall Effect PCB (like the Wooting 60HE, Keychron Q1 HE, etc.).
Furthermore, polarity matters. A North-Pole magnet switch won’t work on a South-Pole sensor board. Stick to the “Lekker” standard (Wooting/Gateron) and you’ll mostly be safe. Do your homework.
Reality Check
Hall Effect switches replace physical contacts with magnetic sensors, offering superior durability, smoothness, and features like Rapid Trigger. While incompatible with standard mechanical keyboards, they represent the objective peak of gaming switch performance.
