Wow! I am amazed! I never thought that there is a complex and precise manufacturing technology
behind those tiny & cheap reed switches.
One of the many things we take for granted :)

How Reed Switches are Made
We have all used reed switches or reed relays but most of us don't actually know how they are made and what's inside that small glass ampoule.
Reed switch has two contacts which are usually normally open and when it gets affected by nearby magnetic field the contacts close and make a closed circuit. Reed switch can also be used to make a relay. This is done by adding a wire coil around the reed switch. When coil is energized it creates a magnetic field which causes reed switch to close (or open).
Be sure to check the video of reed switch manufacturing!
