When you need a single-pole toggle switch that can handle the demands of commercial construction and heavy-duty DIY projects, this 20A/120-277VAC Commercial Specification Grade switch delivers. Rated for motor loads up to 1HP at 120V and 2HP at 240/277V, it's built for lighting circuits, motor control panels, and multi-voltage commercial installations where reliability is non-negotiable. Silver-cadmium contacts (.031" thick), a steel strap with stamped product ID, and side-wire terminations accepting 14-12 AWG conductors make for fast, code-compliant rough-in on any job site. The framed thermoplastic body and nylon cover hold up in demanding environments (-40°C to 65°C operating range), while Canadian certification and full UL/CSA compliance mean it passes inspection the first time. Backed by a 10-year limited warranty, this is the switch contractors reach for when the spec sheet matters.
