    There is a "click" built inside the Earth hole. When inserting a standard 3-pin plug into the socket, the Earth-pin pushes the "click" aside. In so doing, the covers in the Live and Neutral holes are moved out, enabling the Live and Neutral pins to be inserted into the socket.

    A plug without the Earth-pin would not uncover the Live and Neutral holes. Thus the plug cannot be inserted into the socket.

    Prevention of electric shock can be achieved by using an earthed plug connected to an electric appliance,
