Hybrid post-1989 socket
Gaza has standardized on type H sockets and plugs. Nowadays, type C plugs can also be used thanks to their compatibility with type H sockets.
This was not the case before 1989, when the plug still had flat prongs. Power outlets made since 1989 accept both flat and round pin plugs. The original flat-bladed type H plugs have now become obsolete, but they can still occasionally be found. This plug is also used in the West Bank and all of the Gaza Strip.
Strictly speaking, type H sockets are incompatible with type E or type F plugs, because the diameter of the socket contacts is 0.3 mm smaller than the prongs of E/F plugs. However, if you push really hard, you can often force such plugs into a type H outlet. Bear in mind, though, that the appliance will not be earthed and that it is very hard to pull the plug back out!
