My wife and I were on a flight from one US coast to the other, and that gave me plenty of time to think about how to make a switch that would keep dust out. I did not need a waterproof seal, and the pluggable blade design would make that more challenging than it would be worth. The concept I landed on would be a two-part print. The part I drew in blue would cover a 12x12mm tactile switch with a tall bezel where I would place a piece of elastic material so it hung over the edges. An outer shell, sketched in green, would slide over the bezel and elastic material, but hold the material in place. The piece would fit together snugly, and the elastic would seal the edges while still allowing users to press the pushbutton. Since the elastic material should not flex at the edges, it should not allow much dust to leak in the sides. It should also be easy to disassemble and shake any debris off quickly. I wanted to use a thick rubber material, like the kind used for making seals in plumbing jobs, but I think the device will work better with a thin material, E.G., latex party balloons.
