Thanks to all of you for the responses. The fans are 120v. I just
assumed that there were diodes available for line voltage - they make
hydraulic check valves for all sorts of pressures.

Diodes do not work as switches in AC circuits. You will need a proper
switch to do the job on AC.

The only way that comes to mind with AC would be to add an AC-coil
SPST NO relay and I think a double pole switch will be easier and
cheaper.
