I can confirm that Honda Part #35101-MN4-010 (base contact from late 80's CBR600F) fits the 90's CB750s. The switch housings are identical. The CBR600F switch has six wire soldered to contacts while the CB750 switch has only two wires for the connected. Parts bin indeed...
The new switch made a dramatic difference. Idle and lights are noticeably stronger. Still a little slow to warm up, but perhaps that is now because it's been sitting in the garage the past month :/. Also FWIW, it is possible to snap open the base contact and sandpaper the contact surfaces. However, in attempting to do so, I lost one of the internal ball bearings off in the great beyond, so do exercise caution if attempting.
