Product details

The AS-20 Automatic Day Night Switch (20A) is a photocell-based lighting controller designed to automatically operate lights based on surrounding daylight levels.

The built-in light sensor detects sunlight and automatically turns lights ON at night and OFF during the daytime, eliminating the need for manual switching and improving energy efficiency.

With a 20-amp load capacity, the AS-20 model can handle higher electrical loads compared to standard sensors, making it ideal for street lights, garden lights, building lighting, and industrial outdoor lighting systems.

The switch is designed for reliable outdoor use and can control various types of lighting such as LED floodlights, security lights, and pathway lights.
