This Reed Switch is used to detect magnets nearby. The two wire contacts are encased within a glass tube and placed a fraction of a millimeter apart. Whenever a magnet is nearby, it pulls the contacts together and closes the circuit! Simple and effective!

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.
