Lutron Master 120v Switch with Occupancy Sensor

The Maestro 120v Switch with Occupancy Sensor saves energy by automatically turning off the lights when no one is in a room. The 120v version is designed for lighting control only and REQUIRES a neutral wire. Maestro occupancy/vacancy sensors automatically turn the lights on and off. It's ideal for bedrooms, powder rooms, hallways and closets at home, and for small conference rooms and storage areas in the office. 4.6 x 2.4 x 2.3
