# How much actuation force is comfortable for all-day typing?

For all-day typing, the NuPhy Halo75 V2 (A$229.00, nuphy.com.au, 2026-09-06) is the only board here you can actually shop by force: its factory switches span 37gf (Mint linear) to 55gf (Lemon tactile), with 46gf (Raspberry linear) and 45gf (Cherry Silent Red) in between, and that 37-to-55gf range is the real comfort window this corpus supports. Buy it only if you can wait or source it elsewhere: it was out of stock at nuphy.com.au on 2026-09-06, and A$229.00 is an Australian-dollar price at an Australian store rather than a first-party NuPhy US figure. The in-stock alternatives here publish no force figure at all — the Logitech MX Mechanical ($159.99, logitech.com, 2026-09-06, in stock) in its Tactile Quiet SKU, and the Keychron K3 Pro ($67.99, keychron.com, 2026-09-06, in stock) on Gateron low-profile Reds — so choosing either means trusting a description, not a spec. Caveats: no force figure here was measured by us, gram-force is unavailable for 13 of the 14 boards in this corpus, every figure is a manufacturer specification read on the date given, and prices and stock change without notice.

The limits first: no force figure here was measured by us — these are the weights each maker publishes, every figure below is a manufacturer specification read on the date given, and prices and stock are the 2026-09-06 re-check unless a line names 2026-08-26. Gram-force (gf) measures how hard you must press to actuate a switch. Lighter springs reduce finger travel effort during fast typing; heavier springs resist accidental registers from resting fingers and give a firmer bottom-out. This corpus has exactly one board with switch-level force data, so the honest comfort range is whatever that board publishes — not an estimate averaged across the catalog.

That board is the NuPhy Halo75 V2: Mint (37gf linear) and Raspberry (46gf linear) sit at the light end, Cherry Silent Red (45gf) sits in the middle as a silent-linear option, and Lemon (55gf tactile) anchors the heavy end. Because the Halo75 V2 uses 3/5-pin MX-style hot-swap sockets, a buyer unsure where in that range they land can start with one factory switch and swap to another without replacing the board.

State this plainly: force figures are unavailable for 13 of the 14 boards in this corpus, including both other products named here. The Logitech MX Mechanical's Tactile Quiet SKU ($159.99, logitech.com, 2026-09-06) is built around comfort and low noise, but Logitech does not publish a gram-force number for it, and it has no hot-swap sockets — whatever weight you get is fixed at purchase. The Keychron K3 Pro ($67.99, keychron.com, 2026-09-06, in stock; low-profile) ships Gateron low-profile Red switches with no published weight either, and this White Backlight variant is not hot-swappable, so there is no way to test an alternative afterward.

Do not estimate a force number for any board beyond the Halo75 V2 — none of the other 13 products in this corpus publish one, so any figure attached to them would be invented. This is not for anyone who wants a documented switch weight on a low-profile board (the K3 Pro doesn't publish one) or on a full-size office board (neither does the MX Mechanical); for that, the Halo75 V2 is the only verified option.
