Buying keyboard switches goes wrong when the board cannot take them or the pins do not match. This checklist gets SA buyers through compatibility before they order, so the set actually seats.
Quick Answer
Before ordering keyboard switches, confirm three things: your board is hot-swappable, the switch pin layout matches (3-pin plate-mount versus 5-pin PCB-mount), and the switch type suits your use. A 70-90 switch set runs R250-R700, so checking compatibility first saves a wasted buy.
Hot-swap and pin layout
Switches only swap freely if your keyboard has hot-swap sockets — otherwise they are soldered in. Then check pins: 5-pin (PCB-mount) switches have two plastic legs plus the contacts; 3-pin (plate-mount) have the legs clipped off. A 5-pin switch fits a 3-pin socket if you clip the legs, but not the reverse without care. Confirm your PCB type before ordering.
Switch type and feel
Linear switches (reds) are smooth for fast gaming; tactile (browns) give a bump for typing; clicky (blues) are loud and best avoided in a shared res room. Actuation force (35-60g) and travel decide the feel. Buy a small switch tester first if you are unsure — it is cheaper than a full set you dislike.
SA buying checks
Confirm hot-swap support, pin count, and that you have enough switches for your layout (a full board needs ~104, a tenkeyless ~87). A premium hot-swap board to put them in runs R1,200-R2,500, so budget for both together. Factor lube and a switch puller if you want a smoother feel. Buy locally for the warranty path.
FAQ
Can I swap switches on any keyboard?
Only on hot-swappable boards. If your keyboard's switches are soldered in, replacing them needs desoldering. Check the spec sheet for 'hot-swap' before ordering loose switches.
What's the difference between 3-pin and 5-pin switches?
5-pin (PCB-mount) switches have two extra plastic legs for stability; 3-pin (plate-mount) do not. A 5-pin switch fits a 3-pin board if you clip the legs, but always confirm your PCB type first.
Which switch type should I choose?
Linear (reds) for fast gaming, tactile (browns) for mixed typing, clicky (blues) only where noise is fine. Actuation force of 45-60g suits most users; a cheap switch tester avoids buying a full set you dislike.
board is hot-swappable and check the pin layout before ordering switches — a R250-R700 set is wasted if it cannot seat in your PCB. A small switch tester first saves regret.
