Leviton Telcom M1221-T Locking Toggle Switch 20A

Product Description

The LEVITON TELCOM M1221-T is a Lev-Lok locking toggle switch designed for single-pole switching applications at 20 amps and 120/277 volts. The Lev-Lok mechanism requires a deliberate twist-and-pull action to disengage the toggle, preventing accidental switching in commercial, industrial, and trade environments. This switch is sold as an individual unit and is typically installed by licensed electricians in branch circuit applications where unauthorized or unintentional operation is a concern. The combination of 20A capacity and dual-voltage compatibility makes it suitable for both standard 120V and 277V lighting circuits found in commercial installations.

The M1221-T is intended for use in commercial and light industrial settings where branch circuit control requires a tamper-resistant or lockout-capable toggle device. Typical installation scenarios include lighting panel circuits, equipment shutoff points, and any application governed by NEC requirements for single-pole switching at 20A. Its single-pole configuration supports straightforward line-side to load-side wiring on standard switch legs.

Key Features

• Lev-Lok locking mechanism prevents accidental or unauthorized toggling
• Single-pole configuration for standard branch circuit switching
• 20A current rating supports full 20-amp branch circuit loads
• Dual voltage rated at 120V and 277V for residential and commercial lighting circuits
• Sold individually, one unit per package

Compatibility

Designed as an OEM-style replacement or new-installation single-pole locking toggle switch for 20A 120V/277V branch circuits in commercial and industrial electrical systems.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize the circuit at the breaker panel and verify zero voltage with a meter before wiring. Secure all connections per NEC requirements for 20A devices and ensure the switch is mounted in an appropriately rated enclosure for the installation environment.
