Hi Jason,

I have used the DG201 analog switch, it tolerates 36V and switches with
5 volt logic, very easy to use.

They are still made although there might be more modern versions of it.

And if you don't need high voltage then CD4051 etc are also logic level
switching as opposed to CD4066 which needs logic swing to match the
analog rails.

Cheerful regards, Bob
