This is a big reason why I invented my own 3D printable key switches and keyboards that use magnets instead of springs! Check it out: https://github.com/riskable/void_switch https://github.com/riskable/void_switch In space, a spring could fly off who-knows-where and you can't change how strong it is--you need to use a different spring if you want that! With magnets, you can change how strongly they pull apart just by changing how far apart the magnets are at rest (aka "the void"). It's best not to rely on injection-moulded parts in space because it would be cost prohibitive to keep all those moulds on-hand on every ship/station. This is why 3D printable switches are ideal for use in space. 3D printers work great in zero G! Then there's the fact that traditional switches don't really last very long... Their mechanical contact plates wear out and can even create small sparks which is a major problem in space! With magnets and hall effect sensors the entire keyboard can be contactless and basically air, water, and dust tight. The keyboard I'm typing on right now has all these features and more and the entire top plate can be taken off (e.g. for cleaning or using different switches/layouts): https://gfycat.com/costlyglaringhyracotherium https://gfycat.com/costlyglaringhyracotherium My contactless 3D printable Void Switches should last basically forever because rare earth magnets only lose 5% of their magnetism over the course of 100 years and if any switch wears out or gets damaged it's only a $0.01 3D print away to make a new one (you can re-use the $0.01/each magnets from the old switch).
