Solution Approach 1:

The patent combines the SPDT or DPDT switch, SPDT relay, power consumption measurement circuits, and reporting circuits into a single integrated hybrid switch device. This merging eliminates the need for separate add-on components and reduces installation complexity while maintaining automation capabilities.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The hybrid switch integrates multiple functions including manual switching, remote automation control, power consumption monitoring, and data reporting within a single device that fits standard wall boxes. This multi-functionality replaces multiple separate devices and simplifies the overall system architecture.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Extent of automation

If relays are installed in electrical cabinets with control switches, then remote operation is enabled, but wiring complexity and installation cost increase significantly

Engineering Contradiction:
