Magnetic Reed Switch NC NO COM Surface Mount Wired Door Window Contact Sensor with Cover for Home Security and Burglar Alarm Systems MC-31 5pcs
Differences of NC, NO, NC/NONormally 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 NOTEA 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. Specifications:Model: MC-31Contact Type:
