Reed Switches such as this one are great for detecting magnets nearby. Common uses include, detecting a door opening/closing, detecting a box or enclosure being open/closed, security systems, liquid level sensors, reed relays, proximity sensors, counting devices, etc. The two internal wire contacts are a fraction of a millimeter apart and encased in a glass tube. When a magnet is present, the magnetism pushes/pulls the wire contacts together and closes the circuit.
