When I first got my machine I traced out all the wiring and created a diagram and noted all the components. I found it.
On mine the switch is actually one leg of the incoming high voltage and is wired ahead of the emergency off push button. So mine is a line voltage rated switch. So if I wanted to permanently disable/remove it, I could just run the power wire directly to the EPO push button and bypass it completely.
A think a piece of metal would also work to hold down the switch. It just needs to be something rigid enough and strong enough to hold down the push button.
One thing, if a week/month/year from now you turn you machine on and it doesn’t come on, check that the switch is still being held down firm…DAMHIKT…
