The twilight switch has the function to turn on or turn off the light depending on the brightness where it is installed. Once programmed, it switches the light on at dusk and off at dawn.
Practically, in addition to the simple functions of switching on and off, the twilight switch optimises the use of sunlight, It has a deterrent function against intruders and last but not least it optimizes the consumption of the system with consequent energy saving
As it can be seen, there is a rationalization of the consumption of electricity for lighting, both of private and condominial parts, regardless of the season or weather conditions.
Where lighting is essential, the twilight switch is extremely useful, e.g. public lighting, signage, shop windows, road tunnels etc.
The twilight switches can be wall-mounted, pole-mounted, DIN-rail-mounted with or without external probe.
