Thank you for your detailed explanation. That helps a lot.

Thank you for the reply and guidance. I am not sure whether I understand what you mean by the NEUTRAL is unswitched. HOT comes into COM, where does the NEUTRAL wire goes to ? Are you saying NEUTRAL and EARTH are not used/connected into the relay ?

Sorry for this late jump in here. Can you show me how this is connected from an AC source to the Relay module ? ie . Which wire from the mains are connected to the COM and NO/NC of the relay ? Thanks !

can you show how are the AC wires connected to the relay ? Which wire goes to the COM and NO/NC ? Thanks !
