Dear Friends,

I've Red and Green LED light at home and default position red light are ON with relay (NO),5v Relay which is connected to system and when system had given the commend the relay had change the position (NO - NC) and Green LED light are ON.

Now that things are working but i've need the second option which can change the LED light manually through switch.. I did not find any solution about that.. looking forward to get he solution from genius.

Thanks in Advance...

You can use a DPDT switch to exchange the NO and NC outputs of the relay before going to the lights. There may be a simpler solution, but this is what came to mind.
