Magnetic Keyboards Explained: Switches, Sensors, Why They Are Faster

If you are looking at a magnetic keyboard, the main thing to know is that it reads how far each key goes down. You decide where a press counts, so game keys can fire early and typing keys can stay calm.

The specs come from our product pages and the Keychron Launcher web app, checked on 22 October 2026. We did not run lab timing tests, so this page explains how the parts work.

How does a magnetic keyboard switch measure a keypress?

Short answer: A magnet in the stem moves toward a sensor on the circuit board, and the keyboard reads that distance.

A regular mechanical switch has two metal contacts. They touch at one depth, and that touch is the keypress. The keyboard sees on or off, nothing in between.

A magnetic switch has no contacts to touch. Each stem carries a small magnet. Under every switch, a sensor sits on the circuit board. When you press the key, the magnet comes closer and the sensor reads a stronger field.

The keyboard turns that field reading into key depth. It does this for every key, all the way down the stroke. The spring and stem still give the key its feel. The sensor only does the reading.

A mechanical switch tells the keyboard yes or no. A magnetic switch tells it how far.

Check: a magnetic switch only works in a keyboard built for it, so read the switch line on the product page.

Why is a magnetic keyboard faster than a mechanical one?

Short answer: Your finger travels less before a press counts, and less again before the key can fire a second time.

Two settings make this possible.

Adjustable actuation. You choose the depth where a press counts. A shallow point fires the key earlier in the stroke. On a mechanical switch, that point is fixed when the switch is made.

Rapid Trigger. A mechanical switch must rise back past a fixed reset point before it can fire again. With Rapid Trigger, the key turns off once it rises by the release distance you set. It turns on again once you press back by the press distance. You do not wait for the full reset.

In this diagram, both keys are tapped the same way. The magnetic switch has registered four inputs. The mechanical switch has registered two, because each press must clear its reset line first.

The gain is distance, which saves time for your finger. The signal itself does not travel faster. Repeated taps on movement keys in shooters benefit most.

What can you set on each key?

Short answer: The trigger depth, the Rapid Trigger distances, and up to four actions by press depth.

On the Keychron Q6 HE, the actuation point runs from 0.2 to 3.8 mm. You set it per key, in 0.1 mm steps. A mechanical switch has one fixed active point and one fixed reset point.

Because the keyboard reads every millimetre, one key can do more than one job:

1. Dynamic Keystrokes. Up to four actions on one key. A light press walks in a game, and a deeper press runs.
2. Analog Mode. The key sends a variable input instead of on or off. Racing and sports games use this like a controller stick.
3. Rapid Trigger. Press and release distances can be the same or set apart.

Actuation and Rapid Trigger can be set per key, so game keys can be sensitive while the letters stay calm.

What do 0.1 mm, 0.01 mm and 8K mean on a magnetic keyboard?

Short answer: The millimetre figures tell you how finely you can set a key, and 8K tells you how often it reports.

The full-size Q6 HE comes in two versions. The Keychron Q6 HE 8K adds finer steps and a faster wired report rate.

A 0.1 mm step gives you 37 positions between the shallowest and deepest setting. The 0.01 mm step suits players who tune single keys.

Polling rate is how often the keyboard reports to the computer. At 1,000 Hz, it reports once every millisecond. At 8,000 Hz, it reports every 0.125 ms. Our 8K polling rate guide shows where to switch it on.

Check: actuation and Rapid Trigger change how far you press. Polling rate only changes how often the result is sent.

Where do you change the actuation point and Rapid Trigger?

Short answer: In the HE Mode section of the Keychron Launcher web app, with nothing to install.

1. Open Launcher in a current Chrome, Edge or Opera browser.
2. Connect the keyboard by cable, or with the 2.4 GHz receiver on a wireless model.
3. Select keys by pressing them, or pick them on the on-screen keyboard.
4. Slide the Actuation Distance bar to the depth you want.
5. Switch on Rapid Trigger, then pick Basic Mode for one shared press and release distance, or Advanced Mode to set them apart.

Select one key and turn on Trigger Demo to see where its set depth sits in a press. Test Keys shows each key as you press it. Our HE Mode walkthrough covers each screen.

Check: change one setting at a time, then use it for a few sessions.

Who gets the most from a magnetic keyboard?

Short answer: Players who tap the same keys fast, and anyone who wants different depths on different keys.

• Shooters: Rapid Trigger makes repeated taps on movement keys tighter.
• Racing and sports games: Analog Mode gives variable input from the keyboard.
• Mixed work and play: set letters deep for typing and game keys shallow, on one board.
• Typing all day: set one comfortable depth for every letter key once.

The Keychron Q1 HE uses the same Gateron Double-Rail Magnetic Nebula Switch as the Q6 HE in a 75% layout. Choose it if you want a smaller board without the number pad.

Frequently asked questions

Does a magnetic keyboard feel different from a mechanical one?

The feel comes from the spring and stem, so a magnetic switch feels much like a linear mechanical switch. What changes is where the key fires, which you set yourself.

Are magnetic keyboards good for daily typing?

Yes. The keys feel much like linear mechanical switches, and the sensor reads each key without contact. Set your letter keys to a deeper actuation point so a resting finger does not fire them, and leave Rapid Trigger off on those keys. A deeper point means a light touch no longer counts as a press, so you get fewer stray letters.

How do I choose an actuation point?

Start from how you use each group of keys:

1. For game keys, try 1.0 mm. On the Q6 HE, a setting of 0.8 mm or 1.0 mm shortens the trigger.
2. For typing keys, set a deeper point so light contact does not count.
3. In Launcher, select one key and turn on Trigger Demo to see where it fires, or use Test Keys while you press.
4. Move one step at a time, 0.1 mm on the Q6 HE, and test for a day before the next change.
