Can you make a switch redundant inputs?

So I've got a single PSU switch. I'm more worried about the PDU/ source failing than the switch PSU failing. That may be dumb, but it is what it is.

Is there a way to put two 120v power inputs into a single PSU? So if one side fails, the other fails over?

I know the normal answer is to get a switch with redundant PSUs but I don't need a 100w 1g switch.

Maybe use an ATS PDU? https://www.amazon.com/CyberPower-PDU15M10AT-Metered-100-120V-Rackmount/dp/B00NEHUX08

That adds another component that can fail though.

We use ATS's all the times for single-ended equipment where we have A/B power available.
You can get them used on ebay pretty cheap.
You can get ones that have managed or unmanaged outlets in them like a PDU, or ones that are just the ATS and connect to other equipment like APC SU042X163 2 ft (1)L5-20 out Outlets Rack ATS, 20A, 100/120V | eBay which is only ~$75

@TangoWhiskey9 an important difference in the one I linked and the one @Blinky 42 linked is the power cable. If you are on 120V, make sure you get the right power connector for these.
