Feel free to speculate on the project I'm working on. These are zoomed in and cropped photos. What are these components and what were they made from. But most importantly: WHY!??!????
looks like a cam mechanism on the left, with two electrical contacts on the right. so I would guess a switch that turns on when a shaft is in a certain position.
I agree with UltraMagnus on the cam. I think the contacts on the right might be some sort of pressure switch. So maybe there is an analog read on that, and the position of the cam will result in different pressure and a range of analog values.
The bit on the extreme right of the bottom picture almost looks like a piece of pull chain from a light fixture.
