What is a day/night switch?
A day/night switches outdoor lighting on and off automatically. It consists of a light-sensitive element that registers the brilliance of the ambient light. A switch is activated when the daylight reaches the pre-set level.
Brief changes in light caused by clouds, car lights, lightning etc. will not activate the switch, since there is a built-in time delay.
Today day/night switches is available in many varieties, so it is always important to choose the right system, to suit your needs and control requirements.
Choice of solutions
Before choosing a day/night switch it is important to know:
• The installation site (surroundings)
• Load (light type/number)
• Tolerance requirements (energysaving)
• Adjustment requirements
Day/night switches have the advantage over time switches in that they react to the light level, not the time. This means that day/night switches always switch on the lighting when it is needed, and at the same lux level, regardless of whether it is winter or summer
