Goldpoint, the manufacturer of stepped attenuators sells THIS power switch to use with their attenuators. Even though this sound like a good idea, identical to other pots with built in switch, wouldn't having possibly noisy power lines so near to signal lines?

As I understand, it is supposed to switch the AC on the primary side of the transformer, where the power is the most "dirty"

As anyone used this or has any comments to share?

I know that personally, I would not want any AC lines near my signal lines.

Also, usually its not recommended to just switch the AC power off when the component load is still active. Hard on the regulators.
