2-Gang 2-Way and 1-Gang 2-Way Switch Controlling Same 2 Lights

Hi all,

I've recently moved into a new house and am trying to figure out what the previous owners did to the wiring in our living room. We have two light fittings in the room which are controlled by a 2-Gang 2-Way switch on one side of the room, and a 1-Gang 2-Way switch on the other side.

I would like the switches to be wired in such a way that the 2-Gang switch operates each of the lights independently, with the 1-Gang switch acting as an "override" (i.e. if the 1-Gang switch is on, the 2-Gang switch operates as you would expect, but if the 1-Gang switch is off, then both lights are off regardless of the state of the other switch).

Hopefully, that makes sense, but if not this is what I would like to happen.

| s1 | s2 | s3 | l1 | l2 |
| on | on | on | on | on |
| on | on | off | off | off |
| on | off | on | on | off |
| off | on | on | off | on |
| on | off | off | off | off |
| off | off | on | off | off |
| off | on | off | off | off |
| off | off | off | off | off |


Currently, the lights are behaving as follows.

| s1 | s2 | s3 | l1 | l2 |
| on | on | on | on | on |
| on | on | off | on | on |
| on | off | on | off | on |
| off | on | on | on | on |
| on | off | off | off | on |
| off | off | on | off | off |
| off | on | off | on | on |
| off | off | off | off | on |


I've attached photos showing the wiring for both switches. Any help or suggestions would be greatly appreciated!

The two gang switch is wired as one way switches. Not sure what is going on though. You need some test equipment, have you got any?

Thanks for the reply!

Unfortunately, I don't have anything on hand to test, but I can probably pick something up at the weekend if needed. Do you have any recommendations?
 
I don't get what you want, I can help you get it working as it should, e.g. normal 2 way switching
Sorry if my explanation wasn't clear. I'm hoping that I can have the 2 switches on the 2 gang switch each control one light (basically acting as 2 gang 1 way), with the 1 gang switch turning both of the lights on/off.
