Does anyone know what the max length of wire would be that you could
use for a switch or a pot to the stamp?

drop, ampacity of the wire, etc,etc.
20 GA copper may be only 20 feet, and a 4/0 superconductor may be 1million
miles.
What kind of length are you looking for. Another length problem is noise on
the conductor.
Sorry this isn't a good answer, but the question is like asking how much
sunlight does it take to boil water?

definately clamp the I/O pin to +5 and GND with 1N4148 diodes and add
a 100 ohm series resistor to dampen out and ringing on the line.
Basically a long wire acts like a LC tank circuit so you definately
could generate a voltage spike large enough to smoke your I/O pin.
