Leviton 5643-W – Frequently Asked Questions
1) Can one Leviton 5643-W control two separate lights from two different locations?
That's exactly what the 5643-W is built for. It packs two independent 3-way switches into a single-gang device, so each half runs its own lighting circuit and each can be paired with a second 3-way switch elsewhere in the room or at the other end of a corridor. Two circuits, two switch locations each, one wallplate opening.
2) Will the Leviton 5643-W work on a 277V lighting circuit?
Yes. The 5643-W is rated 120/277V AC at 15A, so it drops onto 277V commercial lighting branch circuits as well as standard 120V. That dual rating is why it shows up in offices, schools and retail where the lighting runs at 277V off a 480/277 system while the receptacle circuits run 120V.
3) Do I need a two-gang box for a Leviton double 3-way switch?
No. The 5643-W puts both 3-way switches in one device that occupies a single gang, so a single-gang box and a single-gang wallplate opening will do. That is the main reason to choose it over two separate 3-way switches, which would need twice the box space.
4) Is the Leviton 5643-W a residential or commercial grade switch?
Commercial grade. It's specified for high-cycle duty in offices, retail, schools and similar buildings, not just occasional household use. For a property manager standardizing on switches across a building with heavy daily traffic, that's the grade you want on the spec.
5) Can I use just one half of the Leviton 5643-W as a single-pole switch and leave the other unused?
The two switch sections are independent, so wiring only one and leaving the other dead is electrically fine. A 3-way switch can also be wired single-pole by using the common terminal and one traveler. That said, if you don't need dual control, a plain single 3-way or single-pole device is the simpler part to install and troubleshoot later.
6) What color and wallplate do I need for the Leviton 5643-W?
The device comes in White. It is not a decorator/rocker device, so it takes a standard toggle-style single-gang plate with two toggle openings, not a Decora opening. Order the plate separately; a switch ships without one.
7) Where can I get the wiring diagram and full specs for the Leviton 5643-W?
Leviton publishes a technical information sheet for the 5643-W covering the device specifications, and it is hosted alongside the product for download. Between that and the terminal markings on the device (common terminal plus two travelers per section), an electrician has what's needed to land a two-circuit, multi-location 3-way install.
