The only switch I use is a MFJ-1704. I use it to switch between antennas though. The port to port isolation is supposed to be 60 db and that is more than enough to protect the front end of the unused rig.
I would make sure the unused port is grounded on whatever switch you buy. Most do but some cheaper ones may not. I would even look on the manufacturer's website and download the manual first. Go with the one that has the highest port to port isolation.
Using the switch with one antenna and multiple radios scares me. Shit happens and mechanical things can fail. It's not a big deal if you knock out a cheap CB set but I won't take the chance with something expensive.

One method is a radio multiplexer. I has been too many years since I did that so finding one is up to you.
Duplexer? They appear to be for running two radios (UHF and VHF) to a dual band antenna.
Yup! That's what they are doing. I handed you the bone now you have to put the meat on it.
Not in the dice rolling mood. Can’t find anything about using one with two HF radios and one antenna.
I know using a switch and two CB radios has been done. That's why I posted a coax switch. Although, I do not use the set up. I feel safer swapping coax from back of radio. You may consider setting up a 11m antenna in another location far away from your big boy radio.
I once keyed up running power and blew my friends radio due to close proximity.
Another aspect I have been looking into, unfortunately time is sparse, is setting up an old bearcat scanner to listen in for transmissions.
Then swapping to that frequency.
