Compatible switch list
Any switch sold as Gateron Low Profile 2.0, including NuPhy's own branded range (linear and tactile options at several weights), drops into the V2's sockets. NuPhy's store labels them per board; if the listing names Air75 V2, you are safe.
Not compatible
- Gateron Low Profile 1.0 (the older Air75 V1 generation): different pin spec, do not mix generations
- Kailh Choc and Lofree's Kailh POM switches: different format entirely
- Any standard-height MX switch
Swapping tips
Low-profile pins are shorter and easier to bend than MX pins; press straight down and check alignment twice. Keep the original switches: resale value on NuPhy boards is better with the stock switch option included.
Picking between the NuPhy options
A workable decision path, since you cannot try before buying: decide linear versus tactile first, then weight. If you came from a laptop keyboard and type fast and light, the community steer is toward the lighter linears; heavy typists who bottom out hard tend to be happier one step up in weight. Tactiles in low-profile formats have a shorter, subtler bump than their full-height cousins, so if you want a pronounced bump you may find even the tactile options gentle. NuPhy publishes actuation weight and travel for each switch on its product pages; trust those figures over secondhand numbers, since the lineup gets revised. Ordering one small pack of a second choice alongside a full set is a cheap way to hedge.
How the sockets hold up
Hot-swap sockets are a wear item, and low-profile pins are the usual culprit when something goes wrong: a bent pin forced into a socket can spread the contacts and leave a key intermittent. Owner reports on the V2 generation are largely uneventful when pins go in straight, and the sockets tolerate the handful of swaps a normal owner ever performs. Sensible habits: swap over a desk rather than a lap, support the board from below near the socket you are pressing on, and inspect pins in good light before every insertion. If a key stops registering after a swap, pull the switch and check for a folded pin before suspecting the board; that is the whole story far more often than not.
Ordering pitfalls on marketplace listings
- Third-party marketplaces mix generations freely. A listing titled for the Air75 can ship LP 1.0 stock; the safe signals are the words Low Profile 2.0 or an explicit Air75 V2 mention.
- Photos are not proof. Both generations look nearly identical in renders; go by the stated spec, not the picture.
- Switch counts vary by pack. Count the keys you plan to fill and check the pack size before checkout rather than assuming one pack covers a 75% board.
- If NuPhy has released a newer board since the V2, do not assume its switches carry back. Confirm the socket generation on NuPhy's product page for your exact model.
