  • Relay - Wikipedia
    A relay is an electrically operated switch It has a set of input terminals for one or more control signals, and a set of operating contact terminals The switch may have any number of contacts in multiple contact forms, such as make contacts, break contacts, or combinations thereof
  • What Is Relay? How Relay Works? - Electronics Hub
    Instead of mechanical operation, a relay deploys an electrical signal to drive an electromagnet, which in turn engages or breaks (connects or disconnects) another circuit Relays can be of different types like electromechanical, solid state Electromechanical relays are frequently used
  • Understanding Relays: How and When to Use Them
    This guide covers relay types, contact configurations, pin labels, selection tips, applications, relay vs transistor comparison, and how to test and troubleshoot relays
  • How Electrical Relays Work - Circuit Basics
