I need to make a circuit to switch high voltage between two parts. Say I have one part A and one part B, separated by a large resistor (2 Mohm) and I have a high voltage supply. I want to switch between setting the voltage on part A and grounding part B, or setting the voltage on part B and grounding part A, switching only when not in operation. How should I do this? In a low voltage application I could use a dpdt switch but this likely won't work for high voltages.
Any help would be greatly appreciated!
