Differences of NC, NO, NC/NO
Normally Closed(NC): When the switch is close to the magnet, the circuit is conductive(light on); when the switch is separated from the magnet, the circuit is not conductive(light off).
Normally Opened(NO): When the switch is separated from the magnet, the circuit is conductive(light on); When the switch is close to the magnet, the circuit is not conductive(light off).
NC/NO Combined: The switch has 3 contact types: NC/NO/COM, you can choose to connect two of the contacts(NC-COM or NO-COM).
PLEASE NOTE
A magnetic door contact can only provide a switching signal to the device. It cannot directly load the power supply and cannot be directly connected to the lamp.
