Simple Selection & Compatibility Guidance

Choosing the right automatic mains light switch kit depends on your specific environment and switching needs. PIR and LDR-based kits are well-suited for everyday illumination-simply mount, connect according to the included schematic, and adjust settings as needed. For more complex loads, programmable timer modules offer scheduled automation, commonly used in school corridors or commercial units with set opening hours.

Sample Wiring Schema

   Earth/Ground

Always verify that wiring matches the kit's supported input/output before commissioning. For student projects or demonstrations, low-voltage simulation is recommended prior to permanent installation.
