Drop-in rules
- MX format only: normal-height mechanical switches with metal contact pins
- Both 3-pin and 5-pin fit; no leg clipping needed
- No optical, no Hall effect, no low-profile formats
Pairing advice for this board
The F75 is a gasket-mounted, foam-filled budget board with a deep stock sound. Long-pole linears exaggerate the thock; lighter or tactile switches trade some of that depth for typing feedback. Because the sockets are 5-pin, enthusiast switches drop in without modification, which is rare at this price.
Swap etiquette
Support the PCB around each socket on your first few pulls to learn the resistance, keep pins straight, and test each switch before recapping. The F75's plate grips switches firmly; pull straight up, never lever.
Mistakes that bend pins
The failure mode on hot-swap boards is almost never a broken socket; it is a bent pin during insertion. Before pressing a switch in, look at both metal pins from the side and confirm they are straight and parallel. Line the pins up with the socket holes, press on the switch housing rather than on a mounted keycap, and stop the moment resistance feels wrong. A pin that meets the socket edge instead of the hole folds flat under the housing and reads as a dead key. Folded pins usually straighten fine with flat tweezers, so a mistake here costs a minute, not a switch, as long as you notice before forcing it home.
Quantity and colorway notes before ordering
Count the physical keys on your unit before buying; 75% layouts land near eighty keys, and switch packs rarely match that number exactly, so buy enough to cover the board with a few spares. A dud or a pin casualty out of a fresh pack is normal, and spares also let you test one switch in one socket before committing to a full swap. One more thing owners ask about: Aula has sold the F75 in multiple colorways with different stock switch pairings over its run. None of that changes what the sockets accept; the compatibility described here applies regardless of which colorway you own.
The sound problem switches will not fix
If your complaint is the spacebar or the larger keys rather than the alphas, hold off on a switch order. Rattle on the big keys comes from the stabilizers, and no switch swap touches that. The community's usual sequence on budget boards is: swap switches for feel and overall tone, then address stabilizer rattle separately with careful re-lubing if it still bothers you. Judge each problem by pressing single keys: if an alpha key sounds fine but the spacebar clatters, the switch under the spacebar is not the culprit. Diagnosing this first saves people from buying ninety switches to fix a two-key problem.
