Good afternoon all,

I wondered if someone could help me...

I am just trying to swap an old 2 way switch for a new chrome one. I've done my other single switches fine however, I cannot seem to find how to do it online given that the colors are blue, black, grey and brown.

It currently says:
2 way: Grey and blue
1 way: Black
COM: Brown
I want to change it to this...

This one is different as it has L1, L2 etc..

I did try the following however, it tripped the electrics so clearly I'm doing something wrong:
L1: Black
L2: Grey and Blue
COM: Both live/brown

Would someone kindly direct me as to where I need to put the cables?

Thank you very much in advance!

The markings are virtually the same.

The switches are triangles, although one of the new ones is upside down.

COM = COM
1way = L1
2way = L2.
 
the 2 brown are connected to the separate coms.
Don't forget you need to fit an earthwire to the terminal.

I've shown blue in L2, it may have to go in L1 for the switch to be 'the right way up'.
