Leviton R66-05634-0TS Single Pole Duplex Switch 15A

Product Description

The LEVITON MFG CO R66-05634-0TS is a single pole duplex switch designed to mount two independent single pole switches within a single gang wallbox space. Rated at 15 amps and 120/277 volts, it also supports motor loads up to 1/2 HP at 120 volts and 2 HP at 240 volts. The combined load across both switches must not exceed 20 amps. UL listed and backed by a limited 10-year warranty, this switch is suited for commercial and residential electrical installations where space-saving wiring solutions are required.

This duplex switch is used where two circuits must be controlled from a single gang location, reducing the need for a multi-gang enclosure. Typical applications include controlling two separate lighting circuits, ventilation equipment, or branch loads from a single box. It is appropriate for both 120-volt and 277-volt systems, making it suitable for commercial lighting applications as well as standard residential branch circuits. Electricians use this device to simplify panel layouts and reduce conduit fill in retrofit and new construction wiring 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 circuit at the breaker panel and verify with a non-contact voltage tester before wiring. Do not exceed the 20-amp combined load rating across both switches. Confirm box fill calculations per NEC Article 314 when replacing or retrofitting in an existing single gang enclosure.
