I also had a similar problem that could not find a solution: I want to switch between two sets of secondaries of an HV transformer. My transformer is 360-330-0-330-360. I would like to switch between the 330 and 360 tap, but could not find a component that could guarantee safety of it, as I have a potential difference of 720 V between the phases.
I would have 200mA current in my case.

I never recommend anyone break the rules, however...
Look at ANY Fender standby switch in the last 70 years, and you will not find a one of them rated for the B+ voltage.

Note the nkk series s switch has different dc voltage and current ratings for whether you are switching on/off a resistor, or an inductive circuit. Switching a capacitor on to another capacitor would void the specs, due to transient peak current.
If you were going to fudge it with just an AC rated toggle switch, then suggest using a 250VAC rated multiple pole switch, and connecting all the poles in series.
