Probably late to this game, but the original invert switch part number is listed with DoD WEBFLIS with a CW part number GF-126-0028, a part number Mouser?has in?stock.? YMMV, as?DoD/Webflis goes on Tek data, and they may have changed part numbers over the years.
?
Another note - we had lots of problems with slide switches when I was an Avionics Tech in the navy - Silver Sulfide contamination was the culprit.? CW slide switches are typically with Silver contacts, and a stored plug-in surely might have been exposed to a Sulphur contaminant.?
?
We had problems with the MIL Spray cleaner for switches - it dissolved the Silver Sulfide, only to have it congregate in the porous phenolic part of the switch.? Hi-Pot testing at 300V yielded a nice blue-green flame, with static resistances of open contacts in the 100's of Kilohms.? Both CW and UID switches were susceptible.? Our problem was an outgassing rubber environmental seal on a rectangular connector, about 1x4 inches in size.? Storage in excess of 12 years (Vietnam war-stock material) didn't help.
