Could be simply a way to make sure the button never moves again. I would have simply taken out the knob, personally.
It could be about sending a message.
A missing knob is easy to fix. Bolting a wrench to the housing holding the knob in place is very explicit. It screams “don’t touch”
Idk to me it screams “solve this puzzle and win a free wrench” /s
I like the creativity of it, and it does solve the problem in a way that’s user-safe. I thought of removing the knob because that’s what I do with my barbecue as I store items on the grill when not in use. Remove knobs, put on grill, close barbecue, cover.
I work on industrial controls. Very likely that the switch is momentary, meaning it’ll go back when released.
Sometimes there’s a little piece of plastic in them to remove the momentary setting, but this works too lol. Fuck it, it’s maintenance.
