What would this thing be called?I'm looking for a mechanical (non battery powered) thingy that can "spring" or "popup" after some time. Ideally this time should be configurable, in the range 5-30 seconds maybe. I don't care about accuracy, even 1-2 second accuracy would be ok. It does not need to spring with excessive force, 50 grams or so are ok.My end goal would be to make a device that can push a (capacitive) button and keep the button pushed for a fixed amount of time.Does this thing have a name? My searches for "mechanical popup spring timer" didn't bring up many results. via /r/DIY http://bit.ly/2WjKVyG
