HBL1557W 20 A White Toggle Switch

The Hubbell HBL1557W is a single-pole, double-throw toggle switch rated for 20 A at 120/277 V AC. It provides momentary contact switching for lighting or motor loads up to 1 hp. The white finish suits standard residential or commercial wall plates. UL listing confirms compliance with applicable safety standards.

Back and side wiring with screw terminals

The switch accepts 14 to 10 AWG conductors via back-wire or side-wire screw terminals, simplifying installation in new or retrofit boxes. A single-gang opening accommodates the device without special mounting hardware. Impact-resistant construction withstands job-site handling and daily operation.

Sustained 20 A rating under continuous load

The 20 A rating applies to continuous operation, not just momentary peaks, so the switch runs cooler on circuits that stay energised for long periods. Momentary action returns the toggle to centre automatically, preventing unintended hold-on. Horsepower-rated contacts resist arcing when switching inductive loads such as fans or small motors.

Questions about this item

Will the 20 A rating hold up when the switch is toggled continuously on a 20 A circuit?

The switch is rated for 20 A at 120/277 V AC and 1 hp, so it is designed to carry that current each time it is actuated.

Does the toggle generate noticeable heat or noise when left in one position all day?

The device is a passive mechanical switch with no active components, so it produces no audible noise and negligible heat during continuous operation.

What wire gauges and tools must I have on hand before installing this switch?

You need solid or stranded copper wire between 14 AWG and 10 AWG, a wire stripper, and a screwdriver for the screw terminals.
