Choosing an Electrical Switch

Two Circuits

One Circuit

Light controls fit standard wall plates. Also known as occupancy sensors, they turn lights on when movement is detected and off when an area is unoccupied. The infrared sensors detect changes in heat sources and require a direct view of the occupants. All have a time delay to turn lights off after a set time.

Multi-Way Wall-Mount Motion-Sensing Light Controls

Control lights on a single circuit from more than one motion-sensing switch. Also known as occupancy sensors, these controls turn lights on when movement is detected and off when an area is unoccupied. The infrared sensors detect changes in heat sources and require a direct view of the occupants. Use up to four controls on the same circuit to detect motion in large rooms. All have a time delay to turn lights off after a set time.

Ceiling-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 unoccupied. All have a time delay to turn lights off after a set time.

Infrared sensors detect moving heat sources and require a direct view of the occupants.

Infrared/ultrasonic sensors minimize false activation by detecting changes in heat sources and motion. They can be set so that only one or both detection methods are required to activate and hold lights on.

Ultrasonic sensors detect movement and don’t require a direct view of the occupants.

Fixture-Mount Motion-Sensing Light Controls for Wet Locations

Rated IP65, these controls are protected from washdowns. Also known as occupancy sensors, they turn lights on when movement is detected and off when an area is unoccupied. The infrared sensors detect changes in heat sources and require a direct view of the occupants. All have a time delay to turn lights off after a set time.

Fixture-Mount Motion-Sensing Light Controls

Mount these controls directly to a light fixture. Also known as occupancy sensors, they turn lights on when movement is detected and off when an area is unoccupied. The infrared sensors detect changes in heat sources and require a direct view of the occupants. All have a time delay to turn lights off after a set time.

Mounting extensions (sold separately) improve the position of light controls.

Wall/Ceiling-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 unoccupied. The infrared/ultrasonic sensors minimize false activation by detecting heat and motion. They can be set so that only one or both detection methods are required to activate and hold lights on. All have a time delay to turn lights off after a set time. The mounting bracket swivels 90° so that the control can be mounted on a wall or ceiling.

Power controllers (sold separately) are required to switch a 120- or 277-volt AC lighting circuit. They have a relay that switches a maximum 20 amp load.

Infrared Noncontact Level Switches for Chemicals

Detect chemical level with infrared light to avoid false switch activation caused by vibration in your tank. Also known as optical switches, these sense the level by reflecting light into a receiver that sends an output current to activate an alarm or control circuit. They are sensitive to light and should be shielded or used in enclosed tanks. Mount them horizontally or vertically.

SPST-NO switches activate when the tip is submerged in liquid and light stops reflecting into the receiver.

SPST-NC switches activate when the tip is exposed to air and light reflects into the receiver.
