i cant quite see the markings on the old switch.... but its made up of triangles of terminals...
The first has a single terminal at the top, 2 on the bottom.... the second switch has the single at the bottom and the 2 at the top. the third is same as the first..... Are the terminals marked C, L1,L2? it may be L1,L2,L3..
Doesnt really matter, as long as you know the single one at the pointy end of the triangle is the common, and the switch basically switches between L1 and L2.
Now for the new switch... it appears the markings are Com1, L11,L12 for switch 1....... Com2,L21,L22 for switch 2 and Com3,L31,L32 for switch 3
You can see they are not in the traditional triangle shape... but i have denoted in bold which terminals belong which switch
