XBox adaptive controller low cost/force buttons

I'm was not prepared to pay $60 plus for a simple push-button to connect to my Xbox adaptive controller so I designed my own...

These can be made as a single button, or a gang of two. They require one mono 3.5 mm jack per switch (I buy a double ended extension and cut in half) and a low cost switch.

I use a piece of cut 3 mm carbon rod as the axle, but an M3 bolt would work just as well.
