The Leviton 18203-CW is a Commercial Specification Grade 3-way toggle switch purpose-built for professional electricians and contractors working on Canadian job sites. Rated at 15A and 347 VAC, it handles the higher voltages common in Canadian commercial and industrial installations — making it a reliable choice for multi-location lighting control in offices, corridors, stairwells, and multi-unit residential projects. The framed Canadian design ensures compatibility with standard Canadian wallplates, while side-wire termination and a self-grounding steel strap speed up rough-in and trim-out. With a 50,000-cycle endurance rating, silver alloy contacts, and permanently marked ratings, this switch is built to perform through years of daily use without callbacks.
