Here's the problem: the second pole in the switch has to be able to handle a voltage of 360VDC. I haven't been able to find any affordable mechanical switches or relays that can handle that spec. Does anyone know a good way to switch that kind of DC voltage, in a way that can be tied in to the mains switch as DPDT?
Closing a switch with 360V is not a difficult problem. OPENING a switch with 360VDC is a SERIOUS problem. And that won't happen. If B+ is delayed, sequencing (a little overlap between the poles) won't be a problem.
I've used LEDs in a bleeder string (high efficiency types for less current), but check with a voltmeter before reaching into a high-voltage area,
