A company called Grayhill makes rotary encoder/ joystick devices.
Might be a bit too large for your application (casing is .65 in,
thread and shaft are taller), but still a cool device none the less.
They turn, they have 8 points of direction (+x, -x, +y, -y, and
combinations), and you can press it like a push button.
