ORNO Twilight Switch with Sensor OR-CR-219 — 20A, 230V, Light Level 2–100 lx

ORNO OR-CR-219 is a twilight switch with an integrated light sensor for automatic control of lighting according to ambient illumination. Designed for switching electrical loads on a 230 V supply, the device operates within a sensitivity range of approximately 2–100 lx and is rated for currents up to 20 A. The compact sensor switch is suitable for both outdoor and indoor installations where lighting should be controlled based on natural light levels, providing hands-free operation of garden lamps, security lighting and other fixtures.

Advantages

The ORNO Twilight Switch offers reliable, automatic activation and deactivation of lighting when ambient light crosses the set threshold between 2 and 100 lux. Its 20 A switching capacity supports a wide range of lighting loads without requiring additional relays for small to medium circuits. The built-in light sensor simplifies installation by removing the need for an external detector, and the device is designed for stable performance on a 230 V mains supply. The adjustable operating range makes it suitable for varied lighting environments, helping reduce unnecessary energy consumption.

Suitable for

• Automatic control of outdoor garden and pathway lighting
• Activation of security lamps and entrance illumination
• Control of garage, shed and outbuilding lighting
• Indoor applications where lights should follow ambient daylight level

Key specifications

• Supply voltage: 230 V AC
• Maximum switching current: 20 A
• Light sensitivity range: 2–100 lux
• Built-in ambient light sensor for automatic switching
• Intended for automatic control of resistive and moderately inductive lighting loads

How to use

Install the twilight switch in a location where the built-in sensor can accurately measure ambient light without obstruction from nearby artificial light sources. Connect the device to the 230 V mains and to the lighting circuit according to applicable electrical regulations and safety standards; ensure connections are made with the power off. After powering up, the switch will automatically close or open the circuit as ambient illumination crosses the 2–100 lx threshold, requiring no further manual intervention.

Usage recommendations

For precise operation, mount the sensor where it receives representative daylight (for example, shaded from direct lamp light and not inside enclosed fixtures). Verify the connected load does not exceed 20 A and is compatible with mains switching. Periodically check the sensor window for dirt or obstructions and follow local electrical codes when installing or servicing the device.
