Wiring newer Lutron style 3-way light switch

[Will_IANAE]

Hi guys

I'd like to switch out the old rocker light switches with Lutron style.

The 3-way ones have terminals X, Y, Z in the picture all on one side.

The Newer style has two on the right, one on the left, A, B, C (ignoring the earth).

Could any kind person please tell me the map from X, Y, Z to A, B, C, please?

Thanks in advance

Will

The dark terminal screw should be common. The other two are the travellers and it shouldn't matter which way they are connected.

The old switch has a copper / brass screw for one terminal - does this indicate common, wold you know?

Difficult to say to be honest. @Megawatt who is a US member may know for definite when he sees this. This is pure speculation but I am guessing the middle screw is common just because the screw is a slightly different colour.

Thank you - yes it is common. All working now - thanks again!

No worries well done.

Will put your hot wire on the left by itself which would be A then put Y to the first screw on the top right which is B and put Z to the bottom right screw. Good luck
