The Flex 12V Automatic Changeover Switch eliminates the need to manually swap between battery and mains power. When plugged into campsite electricity, the system automatically runs your fridge from AC (converted to 12V), preserving your auxiliary battery. Once disconnected, it instantly reverts back to 12V battery supply — ensuring uninterrupted cooling.
Built for serious overlanders and weekend campers alike, this unit is an essential addition to any dual battery or 12V fridge installation where reliability and convenience matter most.
⚠️ Please note. Do not directly connect 220v AC to the change over switch.
