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.
Listing controls
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!
FAQ – Frequently Asked Questions
How does a twilight switch work?
A twilight switch measures ambient light intensity using a light-sensitive sensor. Once the set light level is reached, it automatically switches the electrical circuit on or off. This allows lighting systems to turn on at dusk and off at dawn without manual intervention.
Where are twilight switches most commonly used?
They are most frequently installed to control outdoor lighting, illuminated signage, facade LED systems, or floodlights. They are also well-suited for garden lighting and security lighting circuits, ensuring an automated response to changing light conditions.
How do I choose the right twilight switch?
When choosing a switch, consider the type of lighting load to be controlled and the required sensitivity range. Operating voltage and wiring type are also important for system compatibility. The right choice ensures reliable automated performance under target lighting conditions.
