Hello Everybody.....
Yea, I know it was slightly quiet on my side, but I had to make one point work before I will make 10 of them work.
So after some work and searching I finally got it working. And thank you to Steve for the nice explanation and all the info and pictures.

Here is the parts list

The Point : Peco Code 100 Electrofrog. (modified for ultimate performance)
A DPDT Sliding switch.
2mm Welding Rods for Push/Pull leaver. (knobs I will still have to buy or make)
1.4mm Piano Wire (50mm long) from the sliding switch to the Point.
Frog Wire will go to the centre of the switch
Red to the one side and Black to the other.
Now I have to make 10 of these .....
Pic01 - drill 0.8mm hole in the switch (I started with 0.8mm Piano Wire, did not work, then 1mm, then 1.4mm)
Pic02 and 03 - block with switch and wires fitted.
Pic 04 - Fitment under layout.
Cheers and speak again soon.
