I have made the below circuit:
I made the Arduino output turn on for 1 second, and off for 1 second(repeating square wave). I hear a faint clicking noise but suspect that full switch contact isn't being made as when I connect an LED to the NC pin of the relay, it is always on. And in the NO pin it is always off(this is why it seems to suggest that switch movement isn't being made fully). The relay I am using is the Aromat DS2YE-S-DC5V. It is the one with 8 pins in total.(Yes, the schematic is simplified for the relay, but the question is about if the coil is fully energizing). Is there something wrong with my circuit which is preventing the switch to move to the other contact completely? If you need any more info please ask.
