Noisy switch in G9

[JohanRG]

I hope i ask in the right forum and that it's not a too stupid question!
I have for a long time tried to figure out why my two Diy G9's has noise. I'm pretty sure that one of the problem is that the on/off switch is introducing a lot of noice to channel two, besides moving it, how can I make it less noisy? 
Here are two pictures of the switch: https://www.dropbox.com/sh/ewtdxnr0grwvfjd/AAB82apRRfTyuOgLXfFixRbXa?dl=0

Does it help to move the switch away?

Is that small indicator really certified for mains voltage?

Have you tried twisting the wires going to/from the switch?

..and most important: Please use the long, dedicated G9 help thread - that way we can keep everything in one readable thread..

Thank you! It was the LED/the resistor before the LED who was making the hum

Maybe a better idea to have connected the LED to the DC rails of the supply, as opposed to the AC input? Just a thought...
