Which switches fit the NuPhy Halo75 V2?

Explained
The short answerAny standard full-height MX-style mechanical switch fits the NuPhy Halo75 V2. The hot-swap sockets accept both 3-pin and 5-pin switches, so options from Gateron, Cherry, Kailh, Akko, and NuPhy's own lineup all drop in without soldering. This answer covers the Halo75 V2 specifically, not the original Halo75 or the low-profile Air series.

The details

  • The Halo75 V2 has a hot-swappable PCB that NuPhy documents as accepting both 3-pin and 5-pin MX-style switches. No clipping of the two plastic guide legs on 5-pin switches is required.
  • The board uses south-facing LEDs, which means Cherry-profile keycaps clear the switch housings without the interference problem that plagues north-facing boards.
  • Only full-height MX-style switches fit. NuPhy's low-profile switches from the Air series use a completely different housing and will not seat in this board.
  • Stock switch options are NuPhy's own branded switches and vary by the configuration you ordered. Check the box label or your order confirmation to see which one shipped in yours.
  • Because the sockets are standard MX hot-swap, the choice between linear, tactile, and clicky is entirely up to you. All three types work.

What does not fit

Three categories to rule out before you order:

  • Low-profile switches. Gateron low-profile and other slim formats belong to NuPhy's Air75 and Air96 boards, not the Halo line. The names are similar, the switches are not interchangeable.
  • Magnetic Hall-effect switches. These need a magnetic-sensor PCB. The Halo75 V2 is a conventional mechanical board and cannot read them.
  • Non-MX stems. Alps, Topre, and optical switches use different mounts or sensing and will not work.

What owners actually do

The common community pattern is to run the stock NuPhy switches for a few weeks, then experiment. Popular swaps in owner discussions are heavier linears for typing feel and factory-lubed tactiles for quieter offices. Two habits worth copying: support the PCB from below with a finger while pressing a new switch in, and check that both metal pins are straight before insertion. A bent pin is the single most common cause of a dead key after a swap, and it is usually fixable by pulling the switch and straightening the pin gently.

The trap to avoid

NuPhy's product names invite mix-ups. The Halo75 V2 (full-height MX, this page) and the Air75 V2 (low-profile) are different platforms with incompatible switches, and the original Halo75 V1 is a different board internally even though it also takes MX switches. When buying switches, ignore the model name on the listing thumbnail and match on one thing only: full-height MX-style, 3-pin or 5-pin. If a listing advertises switches specifically for the Air series, they are the wrong ones for this board.

People also ask

Do I need to clip the legs on 5-pin switches?

No. The Halo75 V2 sockets accept 5-pin switches as-is, so the two plastic guide legs stay on.

Will Cherry-profile keycaps interfere with my new switches?

No. The Halo75 V2 is a south-facing board, which is the orientation Cherry-profile keycaps were designed around, so there is no housing interference.

Can I reuse switches from an older keyboard?

Yes, as long as they are full-height MX-style switches with straight pins. Desoldered switches from a non-hot-swap board work fine once the pins are cleaned up and straightened.

Does swapping switches void the warranty?

Hot-swapping is the advertised purpose of the board, so routine swaps are expected use. Damage from bent pins or forced insertion is a different matter, so check NuPhy's current warranty terms if you are concerned.
