So far ON/OFF is working fine. My schematic is as attached. The problem is when I switch ON Lamp 1 - and keep Lamp 2 OFF , still I get (120V between Line and Neutral) If I switch OFF Lamp 1 - the voltage goes off. Can you please suggest what I might have missed? Last edited by a moderator: May 24, 2018

Between Line (L) and Neutral (N) there should be 220V continously, independent of lamp status. I assume the voltage you measure is elsewhere. --> Please show where you measure the voltage. Additionally post a photo of your circuit. Klaus
