Commercial 20 A Toggle Switch
This Hubbell CSB120GY is a single-pole wall switch rated for 20 A at 120 to 277 V AC with a 1 HP motor load rating. It features maintained toggle action, back and side wiring terminals, and a quiet mechanism housed in a gray commercial-grade body. The device carries UL and CSA listings and is intended for indoor commercial environments.
Suited for commercial lighting and motor circuits
Electricians wiring standard 120 V or 277 V lighting branches and small motor loads up to 1 HP will find the rating and wiring options appropriate. Installers who require locking actuators, antimicrobial surfaces, or multi-pole configurations should look at alternative devices. The switch is not designed for residential-only decorative styles or for circuits exceeding its 20 A and 277 V limits.
20 A 120-277 V AC single-pole rating
The decisive specification is the 20 A current rating combined with the 120 to 277 V AC voltage range on a single maintained pole. This defines the maximum load the contacts can carry and the supply voltages for which the switch is listed. Any application exceeding either value requires a different switching device.

Questions about this item
What does the 20 A rating mean for a circuit running at 120 V?
At 120 V the switch is rated for 20 A on a resistive circuit and also carries a 1 HP motor rating.
How does the 120 to 277 V range affect the way I wire this switch?
The device is listed for use on any AC circuit between 120 and 277 V, so the same switch works on standard 120 V lighting circuits and on 277 V commercial lighting without rewiring.
What does the back-and-side wiring method require in the box?
Conductors can be terminated under the side screws or inserted into the back-wire ports, giving two ways to land wires in the same enclosure.
