FIELD: transport.
SUBSTANCE: invention relates to electric power circuit 10 for control of the vehicle wiper drive. Heat accumulator 16 to absorb heat emitted in power switch 14 in drive interlocking is connected with power switch 14. In sudden heat emission is power switch 14 prevailing portion of emitted heat can be tapped to heat accumulator 16 to allow designing said switch with selected parameters and use power switch 14 with higher resistance in electric power circuit 10.
EFFECT: wiper electric power circuit with high-resistance switch.
