FIELD: electricity.
SUBSTANCE: electric driven tool comprises a tool body and an accumulator source of power supply. A module for setting voltage of a contact lead of a tool body sets voltage of a contact lead at the side of the body as equal to the first voltage, when a command to put in action a unit of the tool body drive is issued by means of a switch of the tool body. The module of voltage variation in the accumulator source of power supply varies voltage of a contact lead at the side of the accumulator from the first voltage to the second voltage, when supply of energy from the accumulator source of power supply into the drive unit is permitted.
EFFECT: simplified structure of an electric driven tool.
