Where can I purchase High Voltage AC contactors? Do they have "compact" versions? Contactor must be rated for at least 10kVAC. If available, coil must be rated 115VAC or less.

Thanks for your help!

 

Why are you switching the high voltage? Usually that high of a voltage involves some sort of step up transformer, and the control of the transformer would be on the primary side NOT the secondary HV side. Think of a neon sign, they use around that voltage or a little higher, and the on switch is on the input, not the output.

 

To say nothing of the cost, operating at those voltages!
