The other two terminals are needed for the coil to be connected. Savesave 12 volt relay wiring diagram for later. Outline dimensions, wiring diagram and pc board layout.

Pole refers to the number of circuits controlled by the switch:

Controlling a relay module with the arduino is as simple as controlling any other output as we'll see later on. In this video, i'll connect a 12v interface relay with a single pole single throw (spst) contact. The components and wiring diagrams produce a useful 12v actuator timer. A relay is an electrically operated switch.
