Paulding Circle F was a popular brand around here up until sometime in the late 1970’s or so. Their toggle switches back then had the thicker handles, like a lot of the commercial spec grade switches still do. I always thought their devices and wall plates were pretty decent. We even had them installed in our house when I was a kid and that house was built new in 1972. I guess they went the way of those Thomas square recessed lights, which were also pretty popular back then.
I remember their slogan used to be, "Work smarter not harder".
Paulding & Circle F were 2 different companies, GTE bought Circle F & renamed them "Sylvania", when GTE sold their electrical equipment group it became Challenger wiring devices, what happened after Westinghouse bought Challenger I dunno...
