Help needed Bogner Helios Footswitch

[Medronio]

I recently bought a second Hand Bigner helios that came without the footswitch.
I tried a simple one Button switch with a Y cable i soldered and the FX Loop could be switched, but the channel switching didnt work with the second plug. Now i built a 2 Button footswitch and soldered a Standard wiring to it and now the channels can be switched but the fx loop does not work.
Can anyone please send a picture of the inside of a working 2 Button footswitch of the Bogner helios?
Appreciate your help.

Best regards
Sascha

Mine is just a 2 button Marshall foot switch, works fine no issues.

Did it.
Problem was the cable wiring.
Just had to Cut the Ground connection on one side of the stereo plug.
Thanks
