How to use grounded European plug of coffee maker correctly in middle east countries?
The how would be to find an adapter that accepts and properly grounds a French CEE 7/5 plug to any other plug, then find an adapter from that plug to the Israeli SI-32 plug. Or just find a direct adapter, though I couldn't find any such thing.

Alternatively, buy an Israeli plug, cut off the French plug, and wire in the Israeli plug in its place. If you're not planning on taking the appliance out of Israel at any time, that might be easier.

All the adapters I saw did not have the fixed male grounding pin that the French plug relies on for its ground connection. Perhaps they would make a connection between their center ground and the metal around the pinhole, but I don't know.
