TMR vs. Hall Effect: What’s the Difference in Magnetic Keyboards?
September 25, 2025 - cost-effectiveness, a mature supply chain, and proven reliability, Hall Effect should be a better option. However, if you’re after high precision, low power consumption, and a superior experience, TMR is the preferred choice.

Hall effect is great but TMR is an evolution? : r/keyboards
January 9, 2025 - And there's the Ducky OneX that was announced a long time ago: https://www.pcgamer.com/hardware/gaming-keyboards/duckys-worlds-first-inductive-keyboard-offers-cherry-analog-switches-and-wirelessbut-is-it-better-than-hall-effect/ "Our inductive analogue switches, they don't consume that much energy, so we are able to put to make them on a wireless keyboard." "To do wireless with this, you don't go Hall sensors, you go TMR sensors."

TMR vs. Hall Effect: Applications in Magnetic Switch Keyboards Explained - MonsGeek
July 3, 2025 - That’s exactly why TMR is integrated into magnetic switches keyboards: 1) to boost the precision, and 2) to ensure enhanced reliability for wireless gaming. Let’s dive into the details! TMR stands for tunnel magnetoresistance. The Hall Effect and Tunneling Magnetoresistance (TMR) are both phenomena used in sensing technologies, especially in the context of switches, such as magnetic switches used in mechanical keyboards, but they operate on different principles.

TMR Keyboards - are they better than Hall effect (HE vs TMR)
TMR is basically a slight upgrade from the Hall effect technology. In the case of the first TMR keyboard I’ve used – Monsgeek FUN60 Ultra the switches are just regular hall effect switches.

r/ErgoMechKeyboards on Reddit: Alternative Switch Technologies? Optical, Hall Effect, Induction, TMR
October 20, 2024 -

I'm down a bit of a rabbit hole on alternative switch technologies. Mostly out of curiosity, but I'd entertain a build with them if not excessively complicated. It seems like none of the alternatives are really used in the enthusiast "build it yourself" space as it looks like all of them require significant PCB/software design integration.

Optical, Razer seems like the most prominent example. Do you know of any DIY examples?

Hall effect seem to be growing in popularity, and there may be a few semi-DIY examples from Wooting, Keychron, etc. Again, are there any true build it yourself kits?

What about induction? I saw the Cherry MX multipoint series use this tech, and some news about a Ducky One X keyboard using it that I can't actually seem to find any further real info on. Looks like it requires significant PCB design integration though for induction coils under the switches.

Finally Tunneling Magnetoresistance (TMR). I've seen some news about this technology in game console controllers as an alternative to hall effect, mainly to combat stick drift, but couldn't find anything from a quick search as far as key switches go.

Thanks for entertaining my trip down this rabbit hole.

September 28, 2025 - HE (Hall Effect) switches operate on a non-contact mechanism, unlike traditional metal contact switches. When a key is pressed, a magnet attached to the key stem moves closer to a Hall sensor positioned beneath it.
