Rocker with Mini Slide Dimmer

Adjust the brightness of lights.

Toggle switches stay put in any position; move the toggle up and down to increase and decrease lighting level.

Rocker switches with slide dimmers and mini slide dimmers turn lights on and off with a separate rocker actuator to maintain a desired lighting level.

Multi-Way Light Dimmers

Rocker with Slide Dimmer

Toggle with Mini Slide Dimmer

Often used in large, open workspaces, these switches can be wired on opposite ends of the room to control the brightness of lights on the same circuit. They're also known as three-way switches and work in pairs to control lights from two different locations. The actuator to turn lights on and off is separate from the dimmer to maintain a desired lighting level. They fit standard wall plates (not included).

Smart Ceiling-Mount Motion-Sensing Light Controls

Fine-tune motion-sensing light controls from your smartphone or tablet. Mounting on the ceiling gives these light controls a clearer view of the room than wall-mount sensors, so they detect motion over a larger area. They connect to a free downloadable app using Bluetooth. Use the app to adjust the amount of time lights stay on after people leave, set schedules, or override the sensor so lights are always on. Also known as occupancy sensors, they turn lights on when they sense movement and off after people leave.

Controls with infrared sensors detect changes in heat sources and need a direct view of people.

Controls with infrared/ultrasonic sensors have two detection methods to minimize false activation: infrared to sense heat sources and ultrasonic to sense motion. Use the app to adjust whether both or just one of these triggers will switch the lights.

Controls with a dimmer let you adjust the brightness of your lights.

Add companion switches to control lights manually without having to wire them directly into the light circuit. Attach them to any interior wall or outlet box and pair them wirelessly on the app.

Wall-Mount Motion-Sensing Light Controls

Also known as occupancy sensors, these controls turn lights on when movement is detected and off when an area is empty. They fit standard wall plates. All have a manual time delay that will turn lights off after a set amount of inactivity.

Dimming light controls adjust the light’s brightness.

Controls with infrared sensors detect changes in heat and require a direct view of the occupants. Controls with infrared/ultrasonic sensors detect changes in heat as well as motion to minimize false activations. You can set them to use one or both detection methods to activate and keep lights on.

Controls with an automatic time delay can turn lights off automatically based on usage patterns.
