There are two types of reed switches : "normally open" reed switches and "normally closed" reed switches.
The metal reeds on a normally open switch stay open when there is no magnet near the switch.
In the presence of a magnetic field, the contacts of a normally-open reed switch will close.
A normally-closed reed switch is closed when it is not near a magnet; as a magnet is brought close to it, a normally-closed switch will open.
