The use of earth switches is to send any trapped charge in the line into ground after the line is switched off.
Mainly what happens, when the line is switched off, some charges remain trapped in line due to their own capacity and also due to influence of side by X-line. This trapped charge is dangerous if someone goes for maintenance of that very line. So it is very much required to neutralise that much charge and here comes the use of earth switches.
