I have a decade voltage divider used for range switching in my project. I need a way to switch the multiple different voltages that the divider creates into one output, sort of like a multiplexer shown in the diagram. The device also needs to be able to tolerate 500v on the input, but does not need to be able to switch it to the output.
I have tried mosfets in a simulation, but could never get them to work. If I can't find anything else, I could just use relays, but i'd rather not as they are expensive.
Any help would be great, thanks.
