Schneider Acti9 2.5 Module Smart Programmable Twilight Switch Series CCT15__ twilight switch is a device designed to automatically control lighting or other electrical appliances based on the ambient light level. It typically consists of a sensor that detects the amount of light present in the environment and a switching mechanism that activates or deactivates the connected devices accordingly.

When the natural light level falls below a certain threshold, indicating twilight or darkness, the switch activates the connected lights or appliances. Conversely, when the light level rises above the threshold, indicating daylight, the switch deactivates the connected devices, conserving energy and providing convenience.

Twilight switches are commonly used in outdoor lighting systems, such as streetlights, garden lights, and security lighting, to ensure they only operate when necessary, enhancing safety and efficiency. They can also be utilized indoors for applications like controlling hallway lights or automatically turning on lamps as evening falls.
