Technical Details

Design: The Type J (Swiss) features 2 round pins + rectangular ground pin. The grounding system provides additional safety for high-power appliances.

Safety: This plug type is rated for 220-240V electrical systems. The grounding pin helps prevent electric shock by providing a path for fault current.

Compatibility: Always verify both the plug shape AND voltage compatibility before using adapters. A physical adapter does not convert voltage.
