Like so many other parts will deal with today the choices have dwindled, especially for old stuff. What I've found is Standard Motors Products owns most all the "names" in a large segment of the parts venders and is the supplier of many others. They own besides the old Blue Streak and of course Standard products but also Echlin, Wells, Four Seasons and this lengthy list they make the parts for, Wiki quote: "BWD/NIEHOFF, Intermotor, OEM, LockSmart, TechSmart, and GP Sorensen for engine management and Four Seasons, Factory Air, EVERCO, ACi, Imperial, COMPRESSORWORKS, TORQFLO, and Hayden for temperature control."
And from what I've seen also a lot of the old Delco sensors, switches, senders are reboxed Standard now.
So find a A/C cycling switch is just luck of the draw anymore, roll the dice with any manufacturer and hope it lasts.
Also don't forget most parts are "offshore" these days.
