How many switches do I need to buy for my keyboard?
Switch packs come in fixed counts and layouts have awkward key totals. Work out the real number, including spares, before you order.
Fill in the fields above and the answer appears here.
How this works
- Order spares. Stems break, springs get lost, and buying a second pack later often means a different production batch.
- Hot swap boards let you mix switches; soldered boards do not, so spares matter more.
- Stabilisers are separate and are not included in switch counts.
People also ask
Do I need switches for the stabilised keys?
Yes. Spacebar, shift, enter and backspace all still take a normal switch. The stabiliser sits alongside it, not instead of it.
Why buy spares at all?
Switches occasionally arrive with a bent pin or a gritty feel, and pins bend during installation too. A handful of spares saves waiting on a second order mid build.
Can I mix switch types on one board?
On a hot swap board, yes, and it is common to run heavier switches on modifiers or quieter ones under the space bar. On a soldered board every change means desoldering, so decide before you build.
