I can't imagine how silly this question might seem to a person experienced in electronics but I have a question on grounding that has to be asked. To be more accurate it will stop my life from being a game of Russian rulette with every switch press.
I asume a common ground on a circuit means that the parts marked with the ground symbol are all attached to the same piece of copper on the pcb. If that is right; does this common copper then need to be attached to the earth wire, the neutral, or just left unconnected?
