Connecting power switch on AT PSU to the case

[RogrWilco]

Hi folks. Moved on to the portion of my 486 build where I'm moving the components into the case. I'm wondering if I perhaps don't have a standard AT case? I'm puzzled by how I'm supposed to mount the PSU switch. Please see the attached images. Perhaps this is a non-standard case?

I've come across this before. The mounting posts on the case are too far apart to line up with the screw holes on the switch. I ended up having to make an adaptor bracket out of a strip of metal.

The case is standard, but from a time when the switch was more chunky. The switches on AT PSUs changed at least two times (from big to small and from 4-wire to 2-wire).

Thanks folks. What I want to try is attaching the switch directly to the metal enclosure. Wondering if I should be worried about any risk of short between the switch and the case that would electrify the case and lead to a shock? Opinions from people who know more about electricity than me are welcome!
