Eaton OS310U-W-K Occupancy/Vacancy Sensor Switch, White

The Eaton OS310U-W-K is an occupancy/vacancy sensor switch finished in white, designed to automatically or manually control lighting based on room occupancy. As a dual-mode device, it can be configured to operate in occupancy mode (lights turn on automatically when motion is detected and turn off after the space is vacant) or vacancy mode (lights must be turned on manually and turn off automatically once the space is unoccupied). Eaton engineers wall-mounted sensor switches like the OS310U-W-K to replace standard toggle or decora-style switches, giving building owners and facility managers an easy path to automated lighting control without a full rewiring project. This model integrates into the broader Eaton lighting control ecosystem, which is widely specified in commercial, institutional, and light industrial construction.

Key Features

  • Occupancy/Vacancy Operation: Switchable between automatic-on occupancy sensing and manual-on vacancy sensing to match the energy-code requirements or preferences of the space.
  • Wall Switch Form Factor: Installs in a standard single-gang wall box in place of a conventional lighting switch, simplifying retrofit projects.
  • White Finish: Clean white housing designed to blend with standard wallplates and match common commercial and residential decor.
  • Automatic Energy Savings: Helps reduce wasted lighting energy by shutting lights off automatically when a room or area is unoccupied.
  • Eaton Build Quality: Manufactured by Eaton, a recognized supplier of lighting control devices for commercial and industrial electrical systems.

Technical Specifications

  • Refer to manufacturer documentation for complete technical specifications.

Typical Applications

  • Private Offices and Conference Rooms
  • Restrooms and Break Rooms
  • Storage Rooms and Closets
  • Hallways and Common Areas
  • Energy-Code Compliant Lighting Retrofits

Eaton OS310U-W-K – Frequently Asked Questions

1) What is the difference between occupancy mode and vacancy mode on the Eaton OS310U-W-K sensor switch?
Both modes are available on the same device, and you pick one at setup. In occupancy mode the lights come on automatically when the sensor detects motion and shut off after the space has been empty for a while. In vacancy mode someone has to switch the lights on by hand, but they still turn off automatically once the room is unoccupied. Vacancy (manual-on) is what many energy codes call for in private offices and similar spaces, while occupancy (auto-on) suits restrooms and hallways where nobody wants to hunt for a switch.
2) Can the Eaton OS310U-W-K replace an existing toggle or decora light switch?
That is exactly what it is built for. The OS310U-W-K is a wall-mounted sensor switch that drops into a standard single-gang wall box in place of a conventional toggle or decora-style switch, so a lighting-control retrofit does not require rewiring the room.
3) What is the Eaton part number I should order for a white occupancy sensor wall switch?
Order Eaton OS310U-W-K. That is the manufacturer part number for the white occupancy/vacancy sensor switch, and the -W in the number is the white finish.
4) Which rooms is the Eaton OS310U-W-K sensor switch a good fit for?
Eaton lists it for private offices and conference rooms, restrooms and break rooms, storage rooms and closets, hallways and common areas, and energy-code driven lighting retrofits. In practice it suits single-gang switch locations where one wall device controls the lights for the space it is looking into. Large open areas with obstructions or multiple switch legs are usually better served by ceiling-mounted sensors.
5) Can I standardize a whole building on the Eaton OS310U-W-K for occupancy sensing?
It is part of Eaton's wider lighting control line, which is commonly specified in commercial, institutional, and light industrial work, so facility teams can stock one device type across a building instead of mixing brands at each opening. Because the same unit can run either auto-on or manual-on, a single stocked part covers both the restrooms that need auto-on and the offices a code requires to be manual-on.
6) What color is the Eaton OS310U-W-K and will it match my existing wallplates?
White. The OS310U-W-K has a white housing intended to pair with standard white wallplates, which is the common finish on both commercial and residential devices, so it blends with the rest of a switch run on a floor.
