I'm trying to make a toy phone into a working phone like an older landline. I've spent a good amount of time looking online now but can't find a component that could act like the hang-up sensor (I'm not really sure what to call it), the thing circled in this picture.
To describe it, I need some kind of a button that is likely springloaded that can be pressed down decently easily and still return to an on position when there's no pressure on it. Ideally something meant for RPi projects, so I can easily buy and use multiple since I would like to duplicate this project (as in I don't want to have to buy 10 older landlines and tear them apart just for this one button). If not, I could probably work with anything.
Thanks in advance!
