Description
The LEVITON MFG CO S07-CS315-2IS is a commercial specification grade 3-way grounded toggle switch designed for reliable switching in demanding electrical installations. Rated at 15 amps and 120/277 volts, it also supports motor loads up to 1/2 HP at 120V and 2 HP at 240V. Large silver-cadmium oxide contacts deliver extended service life under repeated switching cycles. Captive mounting screws and large-head terminal screws backed out and staked from the factory speed up side wiring of up to No. 10 copper wire, reducing time on the rough-in. Licensed electricians working in commercial and institutional environments will find this switch built to handle the demands of specification-grade projects.
This switch is suited for 3-way switching applications in commercial, institutional, and industrial settings where specification-grade components are required. Its 120/277V dual-voltage rating makes it compatible with both standard residential-style branch circuits and the 277V single-phase lighting circuits common in commercial buildings. The heavy-gauge rust-resistant steel mounting strap and break-off plaster ears allow for precise alignment during installation in standard single-gang boxes. It ships in a package quantity of 10 units, making it practical for stocking on larger projects.

Installation Notes
Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize the branch circuit at the panel and verify zero voltage with a meter before any wiring work. Use the side-wiring terminals for copper conductors up to No. 10 AWG. Confirm proper 3-way wiring configuration between both switches before restoring power.
