Sorry,

It's a double switch, the left switch controls a downstairs light (one
way) - the right switch controls the upstairs light in conjunction with the
upstairs switch (two way).

I have L1, L2 and common connected on the right switch and just L2 and
common on the left switch - does this change any of the advice given?

TIA

I'm trying to fit a new light switch (2-way, controlling 2 lights).
There
are 2x common 2x L1 and 2x L2 connectors on the new switch.

I wired it yesterday and wired it identically to the old switch (which
had
the same connector labellings). However, the downstairs light now comes
on
when the switch is in the "OFF" position, and turns off when it's in the
"ON" position - and no the switch isn't upside down.

What can I do to remedy this?


Two way switches don't have 'On' or 'Off' positions, both positions can be
on or off depending on the other switch.

This sounds like a troll...
