Does it specifically have to be a nc switch or is it just hiw it's wired will determine the nc position?

Some switches have 3 terminals and you can choose NC or NO.
a NC switch is what keeps this circuit simple. Using a NO switch would require more diode fun that you don't need.
Normally closed as to say there is a connection when not touched. when you push on it, power is lost.
heres a switch with choice of no/nc
