Norton 502 ADA Wall Switch — 4-1/2 Inch Square, Hard Wired, Finish 32D

The Norton 502 is a commercial-grade, hard-wired wall switch designed to activate low-energy automatic door operators. Measuring 4-1/2 inches square, this flush-mount push button features blue and white lettering with the internationally recognized ADA accessibility symbol and a "Press to Open" logo — making it compliant with accessible design requirements for public and commercial facilities. Supplied in Finish 32D (satin stainless steel appearance), it integrates cleanly into corridor walls, lobbies, restrooms, and accessible entrances.

The 502 is a momentary SPDT switch rated at 15 amps at 125 VAC, wired directly into the building electrical system (no battery or wireless components). It is UL Listed and mounts to a standard single-gang or 2-gang electrical box — no proprietary back-box required.

Model clarity: The 502 uses blue/white lettering with the ADA symbol. It is not the 501 (black lettering, no ADA symbol) or the 505 (6-inch square format). Verify the correct model before ordering.
