How do I synchronize 2 light bulbs using relays?

[worthyawa]

Hey everyone, here's my imaginary problem, let's say I have 2 light bulbs, both of them take energy from the same source, however, 1 of them has a button to turn it off, the other one does not. How would I make it so when that button is pressed the other light bulb also turns off? The second light bulb cannot use the same button as the first one, it has to be completely separate from the 1st one except for the null wire.

I learned about relays the other day (just started a couple of days ago and I've been looking at images on a book ) and my brain just won't leave me alone. How would I wire a relay (or 2 in this case?) to make it so once the button is pressed the second one loses power also. I guess it will know the first one has no power because of the null wire?

I made a drawing online but after adding it into a simulator it didn't work. Any help is appreciated.

The purple circle is the button, forgot to add it so had to draw on top of it.

You have to give the coils of the relay a live and neutral feed (and a switch to operate them)

NC is Normally Closed. Power to coil off, relay contacts are closed. Power to coil on, contacts open…

NO is Normally open. Same as above but reversed. Coil off, relay open…. Coil on, relay closed.

have another try.
