If you've been shopping for a new keyboard lately, you've probably started seeing the term "hall effect" pop up more than it used to. It sounds technical, and the name alone doesn't tell you much. But once you understand what's actually happening inside one of these keyboards, it becomes pretty clear why they've generated so much attention in the keyboard community over the last couple of years.
This guide covers everything you need to know about hall effect mechanical keyboards: what they are, how the technology works, how they compare to traditional mechanical switches, who they're suited to, and what's currently available in New Zealand through Keychron NZ.
What is a hall effect mechanical keyboard?
A hall effect mechanical keyboard is a keyboard that uses magnetic sensors rather than physical metal contacts to detect each keystroke. In a traditional mechanical switch, a keystroke is registered when two metal contacts touch and complete an electrical circuit. In a hall effect keyboard, that physical contact never happens. Instead, a magnet inside the switch stem moves past a sensor, which detects the change in magnetic field and converts it into a signal your computer can read.
The principle behind this goes back to 1879, when physicist Edwin Hall discovered that passing a magnetic field through a conductor creates a measurable voltage difference. That discovery has been applied in industrial and engineering settings for well over a century. Its application to keyboards is more recent, but the underlying science is well understood and proven.
What this means in practical terms is a contactless switch. No metal touching metal, no friction between contact points, no wear from repeated impact. That single design difference has significant implications for how the keyboard performs, how long it lasts, and what features it can support.
How do hall effect switches work?
To understand how a hall effect switch works, it helps to first understand what's inside a traditional mechanical switch. A standard mechanical switch has a stem, a spring, and a pair of metal contact leaves. When you press the key far enough, the stem pushes those metal leaves together, they touch, the circuit closes, and the keystroke registers. Release the key, the spring pushes the stem back up, the contacts separate, and the circuit opens again.
Hall effect switches have a similar physical structure in some respects. There's still a stem and a spring. But instead of metal contacts, there's a small magnet embedded in the switch stem, and a Hall sensor sits on the PCB directly beneath it. When you press the key, the magnet moves toward the sensor. The sensor continuously reads the strength of the magnetic field and tracks the exact position of the magnet throughout the entire travel distance of the switch.
That positional data is then processed and translated into a digital signal. The keyboard doesn't just know whether a key is pressed or not. It knows how far the key has been pressed at any given moment, right down to fractions of a millimetre. This is fundamentally different to how traditional mechanical switches operate, and it's what enables the features that make hall effect keyboards stand apart.
What can hall effect keyboards do that mechanical keyboards can't?
The most significant advantage of hall effect switches is adjustable actuation. On a standard mechanical keyboard, the actuation point is fixed. It's set by the physical design of the switch, and you can't change it without swapping the switch out entirely. On a hall effect keyboard, you can set your actuation point anywhere within the travel range of the switch, typically between 0.1mm and 4.0mm. You can dial it in to whatever feels right for your typing style or your game of choice, and you can change it any time through the keyboard's software.
If you want a very light, fast response, you set the actuation point shallow. If you want to avoid accidental keypresses, you set it deeper. This level of control just isn't possible with a traditional mechanical switch.
The second major feature that hall effect technology enables is rapid trigger. On a standard mechanical keyboard, after a key is pressed and registered, it needs to travel back past the actuation point before it can fire again. This reset distance is fixed. Rapid trigger changes this by allowing the keyboard to re-arm the key as soon as it starts moving back up, regardless of where it is in its travel. The moment you release pressure, the key is ready to fire again on the next press.
For competitive gaming, particularly in fast-paced shooters like CS2 or Valorant where you're tapping keys at speed, rapid trigger can make a real difference. It allows for faster repeated inputs and more responsive movement. It's also useful in rhythm games where precise, rapid keypresses are the whole point.
A third advantage is durability. Because nothing physically contacts anything in a hall effect switch, there's no wear from metal-on-metal impact. Traditional mechanical switches are often rated for around 50 to 100 million keystrokes. Hall effect switches routinely exceed this, partly because the mechanism that degrades fastest in a traditional switch, the contact points, simply doesn't exist. For someone who types heavily every day or games for long hours regularly, this longevity is a meaningful benefit.
Finally, some hall effect switches operate more quietly than their mechanical counterparts. Without metal contacts snapping together, the main source of noise is the stem bottoming out and returning, which can be dampened more easily. This varies by switch and keyboard design, but it's worth noting for anyone who works in a shared office or just prefers a quieter setup.
How do hall effect keyboards compare to traditional mechanical keyboards?
Traditional mechanical keyboards have been the standard for serious typists and gamers for good reason. The tactile feedback, the satisfying sound, and the wide variety of switch types available, linear, tactile, clicky, make them genuinely enjoyable to use. They're also available at a wide range of price points, which makes them accessible.
Hall effect keyboards currently sit at a higher price point than most standard mechanicals. The technology inside them is more complex, and that's reflected in the cost. Whether that cost is justified depends on what you're looking for.
If you want adjustable actuation, rapid trigger, or a keyboard that will perform consistently for an unusually long time, hall effect is the clear answer. If you're after a specific tactile or audible switch feel that you already love, traditional mechanical switches still offer more variety in that area. Hall effect switches are currently linear in feel, meaning they don't have the tactile bump that switches like Cherry MX Browns or similar are known for.
For most people who are actively looking to upgrade, hall effect keyboards represent a meaningful step forward in terms of what the technology can do. For casual users who are happy with what they have and don't game competitively, the upgrade case is less compelling.
Who are hall effect keyboards suited to?
Competitive gamers are the most obvious audience. The combination of adjustable actuation and rapid trigger provides a genuine performance advantage in fast-paced games, and it's the reason hall effect keyboards have become standard equipment for many professional and semi-professional players.
Heavy typists are also a strong fit. Writers, developers, and anyone who spends the majority of their working day at a keyboard will benefit from the consistency and longevity of hall effect switches. The ability to tune the actuation point to match your typing pressure means less fatigue over long sessions, and the lack of contact wear means the keyboard keeps performing the same way it did on day one, years down the track.
Anyone who wants a quieter workspace without sacrificing performance will find hall effect keyboards worth considering. The absence of metal contact noise, combined with good dampening, can result in a noticeably quieter typing experience compared to traditional clicky or even tactile switches.
