Can anyone here identify the equipment that used this switch assembly?

It looks very similar to those used on the IBM 700 series, but I
haven't been able to positively match it.

Possibly a SAGE.

No, IBM definitely used that style of switches on SAGE.
Only the Power Off and DC Off switches type switches. I've never seen
the other, concave switches on SAGE.

It was a joke, Eric.

not impossible it's off a 1620. have you searched photos of it?
i know it had thermal issues. I would not be surprised the 700 ibm
series would have thermal issues, but on indicator on a panel like this
would be a bit shy of showing the true extent of a thermal issue with
those system.
However the 1620 was cranky about fans and some logic could overheat and
halt the system, so the thermal light would fit.

I have some closeup pictures of the 1620, and it's definitely not that.
I've also looked at all the IBM manuals available on Bitsavers, for that
period.
