Bought new switch from Amazon
Instead of Com I think it's using LA1 terminal
Any ideas of where the wiring goes be great

New switch and old switch with wiring in pics

Cheers

Looks like L1 and LA1 would be your common. So link those two together. You wont blow it up or anything trying these, your light would either stay on without switching off or it just wouldnt come on. Obviously switch off the power each time you are swapping the cables about.
Put the blue wire for your 1 way switch into L2.
For the two way switch , put the brown and blue wires into the remaining two terminals, if the two way doesnt work just swap the blue and brown wires over. It could be LA and the other terminal as your common, it is just a case of messing about with your wires until you get it right. Didnt any wiring diagram come with the switch?

Not the best photos. Is that an L terminal I see on the right hand side (or left depending on which way you're looking)? As per @Highway Man did it not come with instructions or a diagram? Is there a brand name?
 
Yeah so in the pic you have
On the right as you look at it
L , L1,L2
Then on the left LA , LA1 and LA2

I've always just used switches with Com

Goodness only knows why someone thought L and LA was a good idea.
I guess LA and LB would have been better.

Maybe they had 1-gang switches with L/L1/L2, and wanted to identify the 2nd gang of the 2-gang with minimum changes?

Interesting layout - I wonder how they'd build a 3-gang, or intermediate?
