[Elecraft] Coax Switches for KPA1500

What sort of mechanical coax switches are available for 1500 watts continuous power?

The one item I haven’t yet upgraded since putting the KPA1500 amp in place was a two-position coax switch.  I have the K3/KPA1500 on one side and a standby rig – a K2/100 – on the other, switching either one to the antenna feed.  The Daiwa CS-201A that I have in place now is rated to 2.5 KW SSB but only 1.0 KW CW.  The Daiwa 201GII has a 1.5 KW CW power rating, but it comes only with N-type connectors.  I could use that with three N-to-UHF adapters, I suppose, or redo three coax terminations; but thought I’d ask first if anyone knows of a manual switch with high isolation, unused side grounded, 1.5 KW continuous power capability, and UHF-F connectors.  My Internet search came up empty.

Thanks in advance,

Ted, KN1CBR
