It's a bit pricey, but I use the 1A2R switch from 4O3A:

Works great, switches my KPA between two rigs...

Granted it is pricey but will probably work for you.

I've been using the K3S, P3, KPA500 and KAT500 as my main radio. All three
antennas are selected by the KAT500. I also have a second radio, an older
Yaesu FT-101ZD. This rig can be switched into the lineup in place of the
K3S. I sometimes enjoy using the older rig. In this manner the FT101ZD
output goes through the KPA, then the KAT. I find the KAT plays well, a
little tap of the key will cause it to auto-tune.
I'd like to be able to use the KPA500 as an amplifier, but so far it won't
key. I've tried the RCA Phono plug into the PA Key jack, but as long as
the K3S is connected the KPA won't go into TX without the proper software
signal. I did try with the software keyline interrupter a few months ago,
but that prevented the K3S from switching the amp unless I also used a
Y-connecter and phono cord from the K3S for amp keying. When I did the
keying didn't seem as crisp, though.
The K-Line is all connected as in the diagram on page 5 of the KAT500
manual.
Ideally, I could turn off the K3S, switch the feedline from the K3S to the
101ZD, and have use of both the tuner and amp. Is there an easy way to do
this? Perhaps one of those breakout boxes? Any hints appreciated!
