Supplementary question

Top floor switch is the end of this circuit and controls pendant light in centre of room and the landing ligh in the hallway outside that room

Wire had become detached as I discovered when I removed the old switch plate

But there are only five wires not the six I would need to crest the inverted triangles illustrated above.

Both lights used to work so what configuration would make the new switch control both lights once more?

Thanks again in Advance

View the pics from the post above ,the single red is the switched live to the hall light ,and the T&E connected to the same gang is the switch cable for the bedroom ,EFL.

Yes.

,and the T&E connected to the same gang is the switch cable for the bedroom ,EFL.

Ok.

So how did the two-way strappers, when connected to the other switch switch on the hall light?

So that’s given me power to the landing light but not the pendant in the room.

Yes.

The strappers connected to the second gang would do absolutely nothing ,just sit there. The switch for the hall light turned the hall light on/ off ,as the bedroom switch cable was connected to that gang providing the voltage. Obviously the other two way ,on the lower floor , wouldn't do anything .

Agreed, but that was not what we were told in response to my post #12.

Anyway...
