  • In the electronics world NO means that a device in a non-activated (resting) mode is Normally Open. When the device is activated, in this case when the Magnet and the Reed Switch comes in contact, that normally open switch closes.

    What you are looking for is a NC switch, that stays open as long as the door is closed, and once the door opens and the switch goes back to it's rest position of "Normally Closed" the lights activate.

No public wish lists :(
