What is a day-night switch
1 answer
A day-night switch is an electrical device that turns on and off lights automatically depending on the amount of light present in the environment. These switches have a photocell that measures the level of outdoor light and turns on the light at night or when there is low light, and turns it off during the day or when there is sufficient light. Day-night switches are commonly used to conserve energy and reduce electricity bills. They are often installed in outdoor lighting systems, street lamps, parking lots, and industrial facilities.
