Using a switch for your three devices' RS232 connections reduces the number
of parts on the desk and the number of COMn allocations in your O/S. It may
work for you if your only use for RS232 is occasional firmware updates. In
fact, for that you could lose the switch, too, and just swap connectors.
But there are nice operating aids on the Operate pages of the KPA and KAT
Utilities that you might want to use while also operating the radio and
controlling it with a logging program. There are also some third party apps
that help with KPA and KAT operation and take up less screen space than the
Elecraft Utilities. If you operate remotely, one or the other is almost
essential. I always use separate RS232 connections for each device. No, I
don't have lots of real serial ports on my computer - just one, actually.
But I use lots of USB-Serial adapters with considerable success. They add
some maintenance chores but to me they're worth it.

Have fun,
