I'm trying to figure out how a relay functions in a circuit and I'm having trouble figuring why it has the effect it does in a circuit. I set up a simple circuit (see picture) using a 5 pin [ouaz-ss 105D] relay where the LED on the bottom lights up while the push button is not pressed. When the push button is pressed, the relay switches over to the LED on the top. Now, I understand how a relay works for the most part (I drew a schematic of the circuit I made but PLEASE correct me if there are any mistakes in my diagram) but here's my dilemma. When I remove the relay from my circuit (physically pluck it off the circuit board), both LEDS light up. As you can see in my schematic, the relay seems to be in parallel with the two LEDS which leads me to the following question: Why wouldn't the current still travel across both LEDS when the relay is still part of the circuit and light up both LEDS? Shouldn't current travel across both branches (through both 1KΩ resistors and then the LEDS) in this parallel circuit? Is there something significant about having one of these branches grounded (via the relay) which stops the flow of current through the other branch? Any help would be very much appreciated!
