Why Choose the Finder 12.A1.8.230.0000 SMARTimer Astronomical Time Switch?
The Finder 12.A1.8.230.0000 is an advanced single-channel weekly astronomical digital time switch designed for automatic control of electrical loads according to programmed schedules and calculated sunrise and sunset times. As part of the Finder 12 Series SMARTimer range, it combines conventional weekly time programming with astronomical functions for lighting, building services and other applications that need to follow seasonal changes in daylight.
This programmable time switch provides a SPDT changeover output and supports ON/OFF, pulse, Astro ON and Astro OFF functions. Sunrise and sunset times are calculated according to geographical location, while an astronomical offset allows switching to be advanced or delayed around the calculated times for greater control flexibility.
With a 110–230 V AC/DC supply and a 16 A output rating at 250 V AC, the 12.A1.8.230.0000 is suitable for a wide range of control installations. NFC functionality enables convenient smartphone programming, while its LCD display, screw terminals and DIN rail mounting provide straightforward configuration and installation inside electrical distribution boards and control panels.

Reliable Astronomical Time Control for Lighting and Electrical Installations
Astronomical time switches such as the Finder 12.A1.8.230.0000 calculate sunrise and sunset according to geographical location, allowing connected equipment to follow seasonal changes in daylight automatically. This makes astronomical switching particularly useful for outdoor lighting and other applications where fixed switching times would otherwise require regular adjustment throughout the year.
The Finder 12.A1 combines astronomical operation with conventional weekly ON/OFF programming, pulse control and a holiday programme. Its adjustable astronomical offset enables switching to occur before or after calculated sunrise and sunset, while NFC functionality simplifies configuration and programme management using a compatible smartphone.
Typical Applications
- Street and municipal lighting control.
- Car park and external area lighting.
- Garden and landscape lighting.
- Illuminated signs and shop displays.
- Building exterior lighting systems.
- Electrical loads requiring weekly or sunrise and sunset-based switching.
