Industrial 20 A Illuminated Toggle Switch
The Bryant 4903GLI is a single-gang 3-way toggle switch rated at 20 A and 120/277 V AC for industrial lighting circuits. Its ivory finish and built-in indicator light show the load status when the circuit is off. Screw terminals accept back- and side-wiring for secure connections in conduit systems. The switch meets NEMA WD-1 and UL 20 standards for commercial installations.
Replaces Non-Illuminated or Lower-Rated Switches
Upgrading from a standard toggle without a locator light adds immediate visual confirmation of circuit state in dark mechanical rooms. The 2 hp motor rating supports direct control of small exhaust fans or pumps without a separate contactor. The step is justified when maintenance crews need to verify load status at a glance or when the circuit serves mixed lighting and fractional-horsepower loads.
Fits Standard Industrial Wall Boxes
The 1.7 in overall height matches common 4903-series dimensions for flush mounting in standard metallic boxes. Screw-terminal wiring frees installers from proprietary connectors and works with solid or stranded conductors up to the device rating. The maintained toggle action suits lighting circuits that stay on for full shifts. Not suited for momentary-control or low-voltage signalling applications.

Questions about this item
What wall-box depth does the 1.7 in. tall 4903GLI switch require?
The switch body measures 1.7 in. overall height, so a standard 2 in. deep wall box provides enough clearance for the back and side wiring entries.
Which screw terminals accept the hot travellers on this 3-way 20 A toggle?
The brass screws on one side take the two traveller wires; the black common screw on the opposite side takes the line or load conductor.
When should the illuminated toggle be replaced if the neon lamp dims?
The neon indicator is built into the toggle and is not field-replaceable; replace the entire 20 A 120/277 V AC switch when the glow fades.
