I've got a series of three switches that are located remotely (about 3ft)
from my PIC. On the switch block, I've got the current limiting resistors
for each switch. I had a synapse misfire that makes we wonder if there were
a short in the wire(s) that I could be pulling the port low with a higher
the expected current (my power supply is capable of 1.5a). Can I locate the
switch resistors on the PIC board so that if that happens, I'm safe(r).

Also, wouldn't I be better off setting the port high for an on (instead of
pulling low) condition so that if there is a wiring ground fault, I don't
have an unexpected port change? I assume I'd have to then worry about over
sourcing...which should be predictable since the load is a switch.
