Electro Pneumatic Components Part 5 (Relay)

In this video, we explore the relay—a key electromechanical component widely used in control circuits. You'll learn how a relay works, its internal construction, and how it uses electromagnetic force to switch contacts. We explain: What a relay is and how it functions as an electromagnetically actuated switch The role of the coil, armature, contacts, and return spring Why relays are preferred for signal processing and handling high power How relays differ from push button stations The concept of interlocking in relays for safety in control systems Relays are identified as K1, K2, K3, etc., in circuit diagrams and are essential for both industrial automation and everyday electronics. This video is perfect for beginners in electrical engineering, automation, and electro-pneumatics.
