Hi,
I need to make a safety feature for my project, but I losing track on how to go about it. Firstly, I need a relay or a switch that work like this, but wonder if it can be done.
Line A will be input control, (also 12v), Line B will be supply(12v) to control main circuit to start. When line A have current flowing, Line B should cut off and vice versa.
How should I make it simple, I am not very pro in electronic stuff.
