The Alpha Delta 2B fills the bill. Don't know how I missed it in the Google search.
Pricey at $75 but they have another advantage -- both sides grounded when the switch is in the "COM" position. That isn't the case for the Daiwas. If I have done the math right, 50 db isolation yields 15 milliwatts down from 1500 watts - should be OK for a K3/KPA1500 on one side and a K2 on the other. Thanks!

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.
