Changing old UK light switch to modern switch
I have a two gang switch with pre 1970 wiring.
One switch is one way to bathroom and other switch is a two way switch for hallway. The first picture is old switch with bathroom switch on the left of the picture, second picture is switch that i want to use.
Can someone tell me which wire goes where on the new switch please.
Thank you.

Answer:
The new switch is essentially the 'other way up' visually.
So, without rotating,.
Take the red & black from the lower right & move to the upper right 1 & 2.
Take the single black & move it to upper left 1.
Move the pair of reds to lower left Com & the single jumper from that to lower right Com.
As you don't seem to have any earth in the old wiring, it would be safest to use a plastic back box rather than a metal one. No, it's not to current regulations, but it's 'better' than the regulations when that wiring was first installed.
