A lot of people won’t touch electrical, and the problem with modifying the wiring is you need to be able to clearly document or show what was changed in case it needs to be reversed later.
This is ugly, but it’s immediately obvious how to reverse it to anyone who looks at it. And that pipe wrench probably wasn’t being used anymore anyways. I doubt they tapped the holes, those are probably just self-tap screws that both drilled the hole and cut the thread as they screwed in. No one will call this an elegant solution, but if it works it works.
If you’ve ever worked in maintenance, active production, etc, you’ll be lucky to even have schematics. And trust me, there are a lot of hacks of people fucking with controls for 30+ years straight that soooo much of it is full of “fixes” like this, whether it’s something pushing a button in, or pieces of metal instead of fuses, or wires jumping over what’s “in the way” like whole safety systems and e-stops, contactors forced to run, etc etc etc.
I’m sure they just needed a way to lock the selector knob to the primary position, and didn’t want to rewire it.
Drills and taps two holes, adds a metal strap, and sacrifices a tool to save a 5 minute fix of jumping over the contact with a 2" piece of wire lmfao

“documenting the change” is a pipe dream.
