Product Identity

The Legrand PS20AC1WL is a single-pole locking wall switch rated at 20 amps for circuits between 120 and 277 volts AC. It is intended for industrial environments where accidental operation must be prevented and a maintained toggle position is required.

Build and Connections

A red nylon toggle provides visible identification and resists impact in demanding settings. Back and side wiring options give installers flexibility when terminating conductors in standard junction boxes. The locking mechanism secures the toggle in its chosen position without the need for a separate key.

Included Hardware

The switch ships as a complete device ready for mounting; no additional actuators or antimicrobial coatings are supplied. Installers can proceed directly to wiring and commissioning without sourcing extra components.

Questions about this item

What does the 120 to 277 V AC rating mean for circuit compatibility?

The switch handles single-pole loads from 120 V up to 277 V AC at 20 A, covering standard and higher-voltage commercial lighting circuits.

What wall-box depth and wiring method does the back-and-side-wire design require?

It fits a standard switch box and accepts conductors on back push-in terminals and side screws, so plan for enough depth to accommodate both entry points.

How is the locking toggle engaged after the switch is wired and mounted?

After mounting, insert the key into the toggle slot and turn to lock the actuator in the on or off position, preventing unauthorised operation.
