Hubbell 20 A Momentary Toggle Switch

This Hubbell HBL1557L is a single-pole double-throw momentary toggle switch rated for 20 A at 120/277 V AC. It is built for commercial and industrial lighting or motor-control circuits that require a spring-return action. The black locking-style toggle resists impact and meets UL listing requirements for safety compliance.

Suited for momentary control circuits.

Electricians wiring push-button lighting, garage-door operators or momentary motor starters will find the spring-return function and 1 hp rating appropriate. Installers who need a switch that stays in the on or off position without constant pressure should select a maintained-contact device instead, as this model returns to centre when released.

Fits standard boxes with back or side wiring

The switch accepts 14 AWG to 10 AWG conductors through screw terminals and supports both back-wired and side-wired installations. Its single-gang footprint leaves space in the box for additional devices or splices, while the straight-key locking toggle prevents accidental actuation in high-traffic areas.

Questions about this item

What wire gauges can I connect to the screw terminals on this HBL1557L switch?

The switch accepts copper wire from 14 AWG up to 10 AWG on its screw terminals for both back and side wiring methods.

Will this 20 A momentary switch control a 1 hp motor on my existing 120 V circuit?

Yes, the switch carries a 1 hp rating at 120 V AC, so it can directly switch a 1 hp motor on a standard household circuit.

How do I confirm the switch is operating correctly after installation?

Press the toggle; the load should energise only while the actuator is held and de-energise immediately when released, showing the momentary action is working.
