MK light switch

I’m trying to replace an old light switch with a new MK one. The old one has L1, L2 and L3. But it’s not clear where L1, L2 and L3 are on the new MK one?

You have bought an intermediate switch, but it can still operate as a 2-way.

Put red in the top 1.

Yellow in bottom 1.

Blue in bottom 2.

edit: All three wires should have a brown sleeve on, BTW.
