What Does N.O. Stand For?

[Paul Blumhardt]

N.O = Normally Open (as in relay contacts)

N.C. = Normally Closed

Normally = without power applied to the relay coil

I've noticed the letters "N.O." on one of the power supply connector
pins on a couple of Heath schematics.  What do these letters stand for?
