A Synerji 25A day/night (photocell) switch that turns connected lighting on at dusk and off at dawn, so outside lights work without anyone touching a switch. It is fail-safe on, so the lights default to on if the switch fails, and is IP44 rated.
Typical uses are security lights, garden and driveway lighting, gate lights and signage. It runs on 220–240V, uses just 0.7W, and handles up to 5000W of filament lamps or 7 × 250W / 5 × 400W gas lamps. The compact body measures 58mm across and 135mm high.
