They’re not, though. They’re button-activated valves with a fairly complicated flow path, integrated screen, extremely high lifecycle, and pressure regulation to deal with a wide range (one spec I saw said 30-90 psig) of water pressure, all while being contained in a single cartridge for easy replacement.

The details of everyday items are fascinating.

The title is garbage, but the article is good and the mechanism of the water fountain is amazing.

It does make a little more sense when considered alongside its sibling entries in the long-running series ‘Button of the Month’

While we're complaining, does anyone else think the button mechanism is too complicated? That diagram has 50 annotations, which seems like too many for a button.

I know nothing about fabrication or physical engineering, but surely it can't be that hard to make it simpler, like a safety pin or a <second thing>.

Not a joke. Thanks.

It has a lot of annotations because the diagram is detailed, not because the item is particularly complicated.
