There is a common misunderstanding with n/o and n/c. It comes from the home
security industry just making up there own standards and not understanding the
universal switch meanings.
n/o means normally open or if you have a magnet touching the led or motor
would be on.
N/C means Normally closed or if you have a magnet touching the motor or led
would be OFF.
in other words
you wire this switch up to a door when the door is closed and the magnet is
touching the alarm system would be on. and when you open the door the alarm
system would be off
if you have any questions please email me before buying.
