Relay Wiring Schematic - Wiring Diagram

Relays can look very similar from the outside so they normally have the circuit schematic voltage rating current rating and terminal numbers marked on the body to identify them. An led is connected to pin 8 which is configured as an output.

The relay allows full power to the component without needing a switch that can carry the amps.
Here is an example of a time delay relay contact used in a motor control circuit.
This pinout image is only a 2 pole diagram for room on the page purposes but you can get the picture here with this one since a 3 pole will just have 1 more set of contacts.
