Optical switch transmission port has one or more optional, physical or logical operation is switched on the optical signal transmission line or in optical integrated circuits, in actual use, for the conversion of multiple monitors, LAN, light source, detector and Ethernet protection. Then, what are the points for attention to the use of optical switches?

(1) in high ambient illumination, generally can work stably, but should avoid the sensor axis facing the sun light, incandescent lamp and other strong light source, if necessary, shading plate or shading cylinder installed on the long sleeve around the top of the sensor.

(2) the use of reflective diffusion type light receiver, sometimes because the detector is closer to the background, may cause photoelectric switches can not be stable detection. Therefore, the type of investment can be changed to a distance defined by light, or the background, the background from the demolition, will be the background painted matt black, or try to make the background rough, gloomy method to exclude.

(3) when the object is shiny or face smooth metal surface, when the reflectivity is high, approximate mirror effect, when the optical switch and object detection installation angle of 10~20 degrees, so that the optical axis is not perpendicular to the object to be detected, thus preventing misoperation, causing unnecessary damage.

(4) because the dimming switch regulates the light source through voltage changes, it is not suitable for fluorescent lamps, energy-saving lamps, ring lamps and other light sources.

To sum up, the above is the light switch in the use of matters needing attention, for reference only!
