How do relays work? - Explain that Stuff!

An electrical contact is an electrical circuit component found in electrical switches, relays, connectors and circuit breakers. Each contact is a piece of electrically conductive material, typically metal. When a pair of contacts touch, they can pass an electrical current with a certain contact resistance, dependent on … See more A normally closed (NC) contact pair is closed (in a conductive state) when it, or the device operating it, is in a deenergized state or relaxed state. A normally open (NO) contact pair is open (in a non-conductive … See more The National Association of Relay Manufacturers and its successor, the Relay and Switch Industry Association define 23 distinct forms of electrical contact found in relays and switches. Of these contact forms, the following are particularly common: See more When relay contacts open to interrupt a high current with an inductive load, a voltage spike will result, striking an arc across the contacts. If the voltage is high enough, an arc may be struck even without an inductive load. Regardless of how the arc forms, it will … See more • Contact bounce • Latching relay • Wetting current • Wetting voltage • Electrical splice See more Contacts are rated for the current carrying capacity while closed and the voltage breaking capacity when opening (due to arcing) or while open. Opening voltage rating may be an A.C. voltage rating, D.C. voltage rating or both. See more Contacts can be produced from a wide variety of materials. Typical materials include: • See more Ragnar Holm contributed greatly to electrical contact theory and application.
