Hall Effect Switches, Explained

Hall Effect switches went from niche to everywhere in about two years. Every gaming keyboard brand sells one now, every review mentions rapid trigger, and most explanations stop at "they use magnets."

Here is what they actually are, what rapid trigger does that an ordinary switch cannot, and — the part most guides skip — what you need to already own before any of it works.

What a Hall Effect switch actually is

A normal mechanical switch works like a tiny light switch inside. Press the key, two metal pieces touch, and the keyboard registers a press. It only knows one thing: pressed, or not pressed.

A Hall Effect switch has no touching parts. The key's stem carries a small magnet, and a sensor under it reads how close that magnet is. As you press down, the magnet gets closer, and the keyboard measures that distance. The key never physically makes contact.

Two things follow from that, and the rest of this guide is downstream of both.

Almost nothing wears out. There are no metal parts rubbing or pressing against each other, so there is nothing to wear down or get dirty. These switches are rated past 100 million presses — both the UR Studio ICE Ultra and the Gateron Jade Pro are rated beyond that figure.

The keyboard knows how far down the key is, not just whether it is down. A normal switch can only say pressed or not. A Hall Effect switch reports the exact depth, hundreds of times a second. Everything people find exciting about these switches comes from that one difference.

Rapid trigger and adjustable actuation

Because the keyboard tracks depth continuously, it can do things a normal switch simply cannot.

Adjustable actuation point. On a normal switch the press point is fixed — a standard red switch fires at 2mm down, always. On Hall Effect you choose it in software. Set W, A, S and D super shallow so they fire almost at a touch, and leave the keys you rest your fingers on deeper so you don't press them by accident.

Rapid trigger. Normally a key must rise back up past a fixed point before it can fire again. With rapid trigger the key resets the moment you start lifting — release a fraction of a millimetre, press again, and it fires. For counter-strafing in CS2 or repeated jump inputs, you re-press faster because you're covering far less distance.

Analog input and dynamic keystroke. Depth can act like a thumbstick rather than a button — press lightly to walk, fully to sprint, the way a controller trigger behaves. Dynamic keystroke goes further and binds two different actions to two different depths on the same key.

Here is the part nobody mentions. None of these are switch features. They are keyboard features. The switch supplies the moving magnet; your keyboard's software does everything else. A pricier Hall Effect switch will not give you rapid trigger — your keyboard either supports it or it does not, and no switch you buy will change that.

Hall Effect vs mechanical switches

Hall Effect Mechanical (MX)
How it registers Magnet and sensor, nothing touches Metal parts physically touch
Actuation point You choose it in software Fixed by design
Rapid trigger Yes, if the board supports it Not possible
Analog input Yes No
Debounce delay None Typically 1–5ms
Wear over time Nothing to wear out Contacts get dirty eventually
Variety Limited, nearly all linear Huge: linear, tactile, clicky
Works in your current board? Hall Effect boards only Any MX board

Hall Effect wins on gaming responsiveness and lifespan, and it is not close. Mechanical wins on variety and feel. Tactile Hall Effect switches exist, but the selection is a fraction of what MX offers, and clicky Hall Effect barely exists at all. If you want a sharp tactile bump or a deep typing sound, the mechanical world is far deeper — and if you type more than you game, most of the Hall Effect advantage stays theoretical.

Before you buy: the part that costs people money

Hall Effect switches only work in Hall Effect keyboards. They will drop neatly into a hot-swap MX socket and register nothing at all, because there is no sensor under an MX PCB. This is the most common mistake people make with these switches, and it is not recoverable — the switches are not faulty, the board simply cannot see them.

Even among Hall Effect boards, magnetic strength matters. Boards are tuned to expect a particular magnetic range. The four switches below run from 100 GS to 120 GS of magnet strength at rest and from 700 GS to 880 GS fully pressed. A board tuned for one range can read another inaccurately: your press point landing at the wrong depth, rapid trigger that drifts as you play, or in the worst cases keys firing while you are not even touching them.

Check your keyboard's supported switch list before you order. Most Hall Effect boards publish one. If yours does not, ask before committing to a full set — seventy switches is an expensive way to find out the answer.

Which Hall Effect switches to buy in India

These four are in stock and ship domestically from Ahmedabad, so there is no import wait and no customs to clear. All four are linear, all four arrive factory-lubed, and all four come ten switches to a pack.

Switch Initial force Bottom-out Travel Spring Housing / stem Magnet strength (rest) Magnet strength (bottom)
MMD C1 Jiyao 30 ±5 gf 38 ±5 gf 3.3 ±0.1 mm 15 mm Clear PC / LY 100 ±8 GS 880 ±25 GS
Unionwell Polar Ice Shine 35 ±5 gf 45 ±10 gf 3.2 ±0.1 mm 21 mm PC top, POM bottom / POM Not listed Not listed
UR Studio ICE Ultra 35 ±5 gf 48 ±5 gf 3.5 ±0.3 mm 22 mm Modified PC / modified POM 110 ±20 GS 700 ±40 GS
Gateron Jade Pro HE 36 ±5 gf Not listed 3.5 ±0.1 mm Custom Not listed 120 ±8 GS 700 ±30 GS

MMD C1 Jiyao — the lightest

Thirty grams to start and thirty-eight at the bottom, lighter than anything else here by a clear margin, over 3.3mm of travel on a short 15mm spring. It also has the widest magnetic range in the group, from 100 GS at rest to 880 GS fully pressed, which gives a keyboard more signal to work out exactly how far down the key is. This is the pick if you are chasing the fastest possible re-press and you have the finger discipline not to rest your weight on the keys. Clear housing, so RGB carries through cleanly.

Unionwell Polar Ice Shine — the shortest travel

Thirty-five grams initial, forty-five at bottom-out, and 3.2mm of total travel, the shortest of the four. Less distance to cover on every single press adds up over a long session. A 21mm spring keeps the return steady, and the smooth plastic stem running against a smooth bottom housing is where the deeper, poppier sound comes from. The balanced choice: light enough to stay quick, firm enough to stay stable when you are pressing hard.

UR Studio ICE Ultra — the most supportive

Starts at thirty-five grams and climbs to forty-eight at the bottom, the firmest bottom-out here, on the longest spring in the group at 22mm with 3.5mm of travel. That steeper force curve means the switch pushes back as you press deep, which suits heavy typists who would rather the key stopped them than let them slam into the plate. Fully clear housing with dual light guides, rated past 100 million keystrokes.

Gateron Jade Pro HE — the known quantity

Thirty-six grams initial, 3.5mm travel, magnet strength from 120 GS rising to 700 GS, a custom spring, factory lubed, rated past 100 million keystrokes. Gateron is the most established name in this group, and consistency across a full set is what the premium buys you — when you are fitting seventy or a hundred switches, unit-to-unit consistency matters more than any single number on a spec sheet. The safe order if you would rather not gamble on a smaller brand at that quantity.

Quick picks

  • Fastest re-press: MMD C1 Jiyao — lightest press, least distance to travel.
  • All-round gaming: Unionwell Polar Ice Shine — shortest travel, steady weight.
  • Heavy hands: UR Studio ICE Ultra — firmest bottom-out, longest spring.
  • Safest bulk buy: Gateron Jade Pro HE — the most consistent of the four.
