Can anyone tell me anything more about these two toggle switches one from Texas Instruments and the other manufactured by "CH"?

I don't know for sure if they're aerospace hardware but I suspect they'd look out of place on the dashboard of a Ford Pinto.

High-res closeup photos are available on a dedicated webpage here.

The switch at the left is a nice flight-rated Apollo Command Module lever-lock switch. (Upon closer look, the terminals differ slightly from a flight-rated switch, but where it counts it looks like a flight switch.)

The second switch is the type of lever-lock switch used in Space Shuttle simulators, or applications where an environmentally sealed switch is needed. "CH" is Cutler-Hammer, now Eaton.

What criteria is being applying when evaluating as "flight rated"? - beyond the differences pointed out in the terminals there are not correct contract number or inspection/acceptance stamps on this example...

I meant the design and materials of the handle and housing appear identical to flight units, including the lever seal. You are right though, as a unit it has not actually been approved as acceptable for flight.

The CH is Cutler Hammer.
