5 Pin Relay Wiring Diagram With Switch. Electronics Tutorial about the Relay Switch Circuit and relay switching circuits used to control a variety of loads in circuit switching applications. A relay is a programmable electrical switch, which can be controlled by Arduino or any micro-controller.
This wiring diagram applies to several switches with the only difference being the color of the lights.
A wide variety of relay wiring diagram options are available to you, such as application, type.
Below you'll find a basic on/off rocker switch wiring diagram as well as an easy to understand illuminated rocker I'm going crazy, well sort of, I bought an electric fan relay kit that comes with a temperature switch but I. This is generally connected to the positive terminal of your signal source. With a configuration like this the electromagnet of the relay is directly powered from the Arduino Board and if something goes wrong.
