Twilight Switches
Dusk-to-dawn switches (twilight switches / photocell light sensors) are electrical photosensors that automatically switch lighting on or off according to ambient light levels. They are commonly used for controlling exterior illumination, illuminated signage, floodlights, and security systems without requiring manual operation. These switches enhance convenience and energy efficiency by automating light source activation based on real-time daylight conditions.

Twilight switches will save you energy. We offer models with regulation and also without regulation. With them, you can automatically turn on LED light sources, fluorescent lamps or other classical lighting. In areas where night usage is not possible, twilight switches can be combined with the timers and thus disconnect the light source at night. It is important that the twilight switches are not illuminated by the lamp itself during installation!
