KTT Nebula Magnetic

Quick Summary

The KTT Nebula Magnetic is a budget Hall-effect linear made for analog keyboards — the kind that let you set actuation depth in software and enable features like rapid trigger. It trades the fixed click-point of a mechanical switch for adjustability, and does it at a price that makes magnetic boards far more approachable. If you’re building or filling an analog board, the Nebula is a sensible, affordable choice.

Specs and Feel

This is a contactless switch: rather than a metal leaf, it carries a magnet in the stem that a sensor in the board reads. That’s why there’s no fixed actuation force in grams — the trigger point is whatever your keyboard’s firmware sets. The figures that matter are the magnetic flux values (roughly 80Gs initial rising to about 700Gs at the bottom) and the 3.7mm total travel, slightly shorter than a standard 4.0mm mechanical. A POM slider runs against a polycarbonate top and PA66 nylon bottom housing, giving a smooth linear stroke and a medium-thocky sound. The PA66 keeps the bottom-out soft rather than sharp.

Tuning

Magnetic switches are best left mechanically alone — the magnet and sensor alignment matter more than lube, and heavy lube can interfere with the smooth analog travel. The real “tuning” here happens in software: dial in your actuation depth, set up rapid trigger, and configure per-key sensitivity in your board’s app. Stock smoothness is good, so resist the urge to mod these like a normal linear.

Verdict

Buy the Nebula if you have an analog/Hall-effect keyboard and want an affordable way to fill or swap it. It won’t work in a standard mechanical board, so it’s not a cross-shop for KTT’s contact linears like the Kang White or Cabbage Tofu — it’s a different category entirely. As a budget entry into magnetic switches, though, it’s a solid, no-fuss option.
