I'm building a Claus Byrith 4-30 (updated Mullard 5-20) and want to have a front mounted mains switch for convenience, but I don't want to run 230VAC to the front of the enclosure, and risk all the extra mains hum it will likely cause. Has anyone come up with elegant solutions for mounting the mains switch at the back where the power comes in, and linking it mechanically to a front mounted button of some kind?

What about using a 12 Volt relay that can switch mains voltages? With two push to make switches on the front panel you can easily operate such a switch. This system is used to operate industrial machinery. I used it and it is easy to implement.
Note: The relay switch has to have at least two contact points as one has to be used to power the relay's coil.

But where does the 12v come from? I guess it has to be live all the time the amp is connected to the mains?
