About this part
An industrial grade toggle switch rather than a residential one, and the difference is in the guts. Bryant built the 4901 series with a heavier contact set and a strap that survives being torqued into an old steel box, which is why they turn up in plant rooms, machine shops and stage lighting rather than in houses. The rating tells the same story: 20 amps at 120 volts through 277 volts, so it switches a commercial lighting circuit directly rather than through a contactor.
Both wiring methods are on the part. Screw terminals down the side take a fork or a loop under the head, and the back holes take a straight stripped conductor for a faster install. The ivory finish is the 4901-I variant. The current Hubbell Bryant catalogue still lists this part, so a replacement plate or a matching switch is a stock item rather than a hunt, which is unusual for anything in this catalogue.
Ten are on the shelf, counted by hand. None has been wired: the terminals are unmarked, the screws are still at their factory depth, and the toggle has the stiffness of a switch that has never been worked. Wiring devices are the one thing here worth buying new old stock rather than used, because a switch that has carried twenty amps for thirty years is a switch with a story you cannot see from outside.
Questions about this part
What makes this an industrial switch rather than a household one?
A heavier contact set, a stronger mounting strap and a specification grade rating. It is built to be torqued into an old steel box and to switch a 20 amp commercial lighting circuit directly. A residential switch is usually 15 amps and 120 volts only, and its strap will twist if the box is out of square.
Can I still get parts and plates that match?
Yes. Hubbell Bryant still catalogues the 4901 series, so a matching switch or a wall plate is an ordinary stock item. That is rare for anything in this catalogue, and it is the reason these are worth putting in a job rather than a display case.
Does 277 volts mean I can use it on a domestic supply?
It means the switch is rated up to 277 volts, which is a commercial lighting voltage in North America. It works perfectly well at 120. The rating is a ceiling, not a requirement.
Has it been wired before?
No. The terminal screws are still at factory depth with no thread marks, the terminals carry no copper witness marks, and the toggle still has the stiffness of a switch nobody has worked. All ten came out of the same carton.
