The Story Behind MonsGeek FUN60: Magnetic Meets Mechanical, Hall Effect Meets TMR

📅Jun. 16. 2025

This is the story of FUN60 TMR — a keyboard born from real challenges, hard work, and a clear goal: to create a magnetic switch keyboard that offers the best of both worlds — the smooth, reliable feel of Hall Effect technology and the typing satisfaction of mechanical switches.

Hearing the Users, Facing the Limits

Many users kept asking us to develop a dedicated Hall Effect (HE) gaming keyboard that could work with hot-swappable mechanical switches. It was an exciting idea because HE keyboards are known for durability and smoothness, but gamers missed the satisfying click and feel of mechanical keys.

We wanted to deliver both, but soon ran into a big problem. The Hall sensor has to face the magnet inside the switch directly. This meant the sensor’s position on the PCB was fixed, making it impossible to add mechanical hot-swap sockets without interference.

Searching for a Solution — The Sensor Dilemma

We tried to move the Hall sensor to other spots on the PCB to fix this, but it caused sensitivity problems. The sensor couldn’t detect key presses accurately anymore, which is unacceptable for gaming where every millisecond and keystroke counts.
We were stuck — this technical limitation seemed to block the whole idea. The problem became a bottleneck, and for a while, progress slowed down.

Discovering TMR Technology — A Breakthrough

During this difficult phase, Vincent from our team noticed a new trend in gaming peripherals — TMR (Tunneling Magnetoresistance) sensors were being used in joystick controllers and showing much better sensitivity than traditional Hall sensors.
We reached out to the IC manufacturers and started testing TMR sensors ourselves. The results were surprising and encouraging: even when the TMR sensor was placed on the side of the PCB — not facing the magnet directly — it still delivered extremely high precision. The response and actuation accuracy reached 0.01mm, which was beyond what we hoped for.

Putting Theory into Practice

Excited by these findings, we added mechanical switch sockets to the prototype and started real-world testing. The mechanical switches triggered perfectly, showing that the TMR sensor could handle the requirements.
Still, we didn’t stop there. We spent the next three months testing different mechanical switch types, running stability tests, and refining the detection algorithms. The goal was to ensure the keyboard would perform flawlessly even in intense gaming sessions.

FUN60 TMR — A New Option for Gamers

After months of trial, error, and optimization, the FUN60 TMR was ready. We confirmed that TMR sensors can successfully replace Hall sensors, providing a stable, precise, and durable magnetic switch keyboard that supports mechanical hot-swappable switches.

This new design opens fresh possibilities for gamers who want the best of both worlds — durability, smoothness, and that beloved mechanical feel. The FUN60 TMR isn’t just a product; it’s a real solution born from solving tough problems and pushing technology further.
