Voltage detection circuit

Hi all,

I've been asked to design a circuit ( a verification aid to a piece of test equipment) that will detect a voltage range from 250V to 2kV. I was thinking i could do this using a rotary switch to select the required voltage, which would then allow me to use a voltage divider - RC network - comparator circuit to led output.
I would be grateful if someone would confirm i could do this or tell me otherwise.
If anyone has better way of approaching the problem, please let me know.

For starters, read the parts of this thread about how to safely make a voltage divider.

Thank you for that. It will give me a starting place.
