The magnet moves away as we open the door, then why does the reed switch work, like come in contact and produce sound

[@idukunda_lengo]

Hey there! The logic in the circuit is that, when the magnet is near the switch the blades in the reed switch close meaning that the door is closed in this case the buzzer is not triggered, as the magnet moves way the blades in reed now open meaning that the door is opened the the buzzer produces the sound.
