This course explains the construction, operation, and applications of reed switches, one of the most reliable and widely used magnetic sensing devices in engineering. You'll learn how reed switches use magnetic fields to change the state of an electrical circuit without requiring direct mechanical contact, making them ideal for sensing and control applications.

Through detailed animations and clear explanations, the course explores the internal construction of reed switches, including the hermetically sealed glass capsule, ferromagnetic reeds, and electrical contacts. You'll discover how normally open and normally closed reed switches operate, the role of magnetic attraction and bias magnets, and how magnetic field strength affects switch actuation.

By the end of this course, you'll have a solid understanding of reed switch operating principles, common applications, reed relays, and the advantages of magnetic switching technology in industrial, automotive, and automation systems.
