Changeover relay : Two circuits (terminals 87 and 87a ) have a common terminal (30). When the relay is at rest 87a is connected to 30, and when the relay is energised 87 becomes connected to 30 (but never both at the same time). Relay with double output . Terminal 87 is linked to pin number 87b, giving double outputs from the single NO contact.
Relay Switch Pin Diagram | How To Identify A Relay Switch?Relays take a relatively small amount of power to operate the relay coil, but the relay itself can be used to control motors, heaters, lamps or AC circuits which themselves can draw a lot more electrical power. Here we look at relay switch pin diagram and the different kinds of relay switches.
