he internal electromagnetic compatibility design will not affect the normal operation of other electrical devices. In-Wall PIR Motion Sensor Light Switch Motion sensor light switch, 2 in 1 in wall ordinary on/off and PIR infrared switch 2 in 1 light switch - When the switch is turned to "ON" or "OFF", it can be used as an ordinary switch, and when turned to "PIR", it can be used as an infrared sensor switch. Adjustable sensitivity and delay - Light sensitivity and delay can be adjusted by themselves. Sensitivity adjustment range and sensitivity from 30% to 100%. The occupancy sensor light switch features a variable delay from 5s to 7min. Internal EMC -- The internal EMC design does not will not affect the normal operation of other electrical appliances. Commonly Used -- It is commonly used to control lighting and extract ventilation. In-Wall PIR Motion Sensor Light Switch Package weight: approx.74g Color white Size: as shown Quantity sold: 1 piece Input voltage: 110V-240V/AC; Rated load: 500 W for resistive loads such as incandescent lamps, 150 W for inductive loads such as energy saving lamps, LEDs and energy saving lamps. Distance of induction: 10 meters (140 degrees); delay: adjustable from 5 seconds to 10 minutes; Sensitivity: (night and day) adjustable, with normal switching function. The adjustment button is located under the face cover; lift the faceplate with a screwdriver to adjust. The TIME knob adjusts the delay time and the LUX knob adjusts the sensitivity (when set to sun position it will detect day and night, and when set to moon position it will not will only detect at night). Wiring instructions: the 220V live wire is connected to the L port of the inductive switch, and the A port of the switch is the input port of the live wire . About chromatic aberration The goods sold are all taken in kind, but due to different lighting, monitors, etc., there will be a little color difference, which is a normal phenomenon, not a quality problem About the size The dimensions of products sold are all measured manually. Due to different measurement methods and tools, there may be an error of 1-2mm, which is normal
