Cooper Wiring Devices OS310U-W-K Occupancy Sensor Wall Switch
Features Motion Sensing Technology
The Cooper Wiring Devices Occupancy Sensor Wall Switch provides a simple and affordable solution to saving energy. This sensor switch features a fully dimmable nightlight and 'bedroom' mode that keeps lights from turning on at night while the night light is on.
This sensor has simple control features and configurable settings that work with most lighting loads. The Green LED indicates load status, provides locator light in the dark and blinks when motion is detected. This unit replaces a standard light or fan switch while providing a 180-degree field of view and 1,000-feet of motion coverage.
- Works with all popular lighting load types
- Provides 3-way operation when used with a 3-way switch or sensor
- Selectable time delay of 5 seconds (test), 5 minutes, 15 minutes and 30 minutes for lights to remain on after room is vacated
- Ambient light override prevents lights from switching on when there is acceptable light
What is an occupancy sensor?
Occupancy sensors automatically turn the lights on when the sensor detects the presence of a person and turns the lights off after a certain amount of time when the person has left the room. This makes occupancy sensors great for areas such as laundry rooms or garages where hands are often full and you’re unable to reach the switch to turn the lights on.

I can see how there could be a problem with this device if you were replacing a single switch that did not have a neutral in the box. The night light would not work for sure. I don't know how it would affect the function of the motion sensing switch. I have used other Cooper motion switches that do not require a neutral, so I assume this one would work all right.
This motion sensor is a bit pricey at better than $30. But if it works, it's worth it. Seeing the severe issues people have had with it, I'm wondering if this is a quality control problem for the company.
I purchased several of these and also similar units from Leviton (OSSNL-IDW). So far all have worked, but the reliability and feature set of the Cooper units makes them preferable to the Leviton versions. I'll compare both below:
Both have motion-sensing and can be used as just manual on / auto-off and as auto on and off. I use them both ways; manual on in the master bath and auto-on in the guest bath and garage. The timeout duration is controlled by a rotary setting on both, but while it seems to not have any "stops" both units only allow 3 durations for the timeout. I have had older switches where these potentiometers get flaky after a while so this may be better. Neither will dim the lights (making them suitable for some flourescent lights and LEDs that can't be dimmed).
Both do an adequate job of sensing motion and turning the lights on and then off after a delay. My Levition unit has been intermittent, sometimes not turning the lights on and sometimes not turning them off, but right now it seems to be working normally. I'll keep my fingers crossed.
Both have a nice nighlight that you can enable, it shines through the manual button on the Cooper and through the IR window on the Leviton. The Cooper nightlight is brighter, and it also can be set to a preset dim level over a wide range of brightness. This is fantastic. The Leviton dim level is fixed and less pleasing to look at as it has the IR fresnel lens distorting it.Read more ›
One works great -- one doesn't.
It goes to turn itself off, and immediately flips right back on. I thought -- huh odd, so I decided to change it to manual on, auto off. Well, the unit would turn itself off, and then right back on -- forever.
I bought this to save energy -- so having it never turn off is quite disappointing. Perhaps customer support (currently closed) will help.
The wiring however was simple and straight forward. Just make sure you have a neutral and a ground in the box.
Edit: After using these switches for a little less than a year -- we're going to get rid of them for a number of reasons:
1) The switches tend to detect the light turning off as movement -- which causes them to turn back on, right after turning off. This is a huge annoyance.
2) The motion detectors can't see through interior glass. We have one in a bathroom, that is pointed right at the shower. It turns off when you're in the shower. You have to open the door and wave to get the light back on.
3) The switches are poorly designed. Guests always ask us how to turn on or off lights. The button area looks the same as the motion area and people don't know they should push the bottom area. Instead they push the button for the nightlight, because it's in the middle and clearly looks like a button. So guests push the nightlight and the nightlight turns off, but the main light stays on. Along with the nightlight there is a green light. Very confusing...
The Cooper OS310U has a relay built into the switch so it's happy working with any kind of bulb. You do get the audible click when the relay fires, which might bother some, but I've gotten used to it.
The defining feature for me is the nightlight-bedroom mode which you enable by holding the nightlight button down for 5 seconds until it blinks. What this does is force the light into a manual-on mode if and only if the nightlight is on. This means you can go to bed, or watch movies in the dark, or whatever you'd want to do without the light coming on due to motion.
To be honest, I like the Leviton PR-180's functional design with its very obvious On/Off/Auto slider switch and I really don't need the nightlight feature, but after extensively searching, I can't find any other switch out there that does all of this and also works with CF and LED bulbs.
Others have pointed out the wiring requirements are more extensive as compared to other switches, but it does also work in a 3-way (two switch) configuration. You'll need to ensure you've got ground, hot, load, and neutral with the optional 3-way configuration also needing the traveler, so up to 5 connections might be a little daunting. If at all unsure, hire an electrician for health and safety.Read more ›
