Years ago I worked on similar problems with retail stores and dodgy pstn & dsl. If you’re worried about the links themselves you can have one router device with multiple links connected to it and it fails over. They also can have a SIM card inside to failover to (4g I guess these days) mobile networks.
If you’re specifically looking to fail over between router devices… I think the only thing I ever did on that was have multiple exactly the same routers with exactly the same config - one hot and others as spare cold devices on site lying in wait. Not sure I ever used it.
2) "secondary" router connected to an older (and slower) DSL line
3) "tertiary" router connected via 4G SIM
What I do now is simply take the cable out of the "main" router and connect it to the "secondary" one, and if also this one has no connection (cut cable, it happened three or four times in the last couple of years) connect it to the "tertiary" one.
As said, the issue is only if for whatever reasons I am not there, the A/B/C/D rotary selector box would be a simple solution that anyone present could be instructed to use, while connecting and disconnecting cables can be more difficult to explain over the phone.
The hypothetical device I was looking for would be an automated version of that.

Yep, this is how I have the current setup:
1) "main" router connected to a FTTC line
2) "secondary" router connected to an older (and slower) DSL line
3) "tertiary" router connected via 4G SIM
What I do now is simply take the cable out of the "main" router and connect it to the "secondary" one, and if also this one has no connection (cut cable, it happened three or four times in the last couple of years) connect it to the "tertiary" one.
