Hi, I just found your simulator and I was trying to set up a simple circuit with the relay. I used a switch and a 12v battery. The relay is on custom setting, as I have no idea what the 3 displayed settings of the relay mean.
However when I switch on the power supply to the two pins of the relay, nothing happens.
(I did it exactly as showed in this video: https://www.youtube.com/watch?v=7rV3CljwFWQ)
