Try a HVK1/2 relais, Specifications say 8kV (dc) switching voltage. I used it at work upto 15kV (at 8kHz) when it was swiched 'cold' (remove signal -> switch relay -> put signal back on). I think that is the way you intend to use it. This relays (in various configurations) can be found in the Farnell catalog under order codes : 910-855 for SPNO - 5V with push on terminals 910-867 for SPNO - 12V with push on terminals 910-879 for SPNO - 24V with push on terminals 910-880 for SPNC - 5V with push on terminals 910-909 for SPNC - 24V with push on terminals 910-910 for SPNO - 5V with flying leads 910-922 for SPNO - 12V with flying leads 910-934 for SPNO - 24V with flying leads 910-946 for SPNC - 5V with flying leads 910-960 for SPNC - 12V with flying leads They cost arround 50 Euro.
