I am trying to understand relay circuits better. I have two circuits in question below.
Left Image I understand Pins 2 and 9 are the coil contacts. I would wire a microcontroller outpin pin to a transistor and Power Supply (Pin 2) to control the coil activation (Ground Pin 9). I don't understand what would connect to Pin 5 and 6 since I am used to seeing just one Pin at the source of relay circuits like Pin 1 in the Right Image.
Right Image Pins 2 and 5 are the coil contacts. I would wire my microcontroller and Transistor as a switch circuit similarly to above explanation. Power supply + end to Pin 1 and Load to Pin 3 and - end of Load to - end of Power supply, is that correct?
I believe Right Image is more simple to understand but not sure at all about Left Image. If both my explanations are wrong please correct me. Also, if possible can you explain how once the coil is activated how the lever/switch moves? Based on the orientation in the circuit images I don't see how the lever moves to either pin. Unless the image is not the correct orientation of the mechanical components inside the relay. Finally, is it clear if these circuits are latching or non-latching or should the datasheet tell me that?
