Abstract
An electrical apparatus includes an electrical apparatus main body and a battery pack. The electrical apparatus main body has a load, a manipulation switch, a power receiving electrode, a main body control unit for controlling the electric power supplied from the power receiving electrode in response to a manipulation of the manipulation switch, a signal generation unit for generating an on-manipulation signal if the manipulation switch is switched on, and a main body signal electrode for outputting the on-manipulation signal. The battery pack has a battery, a power supplying electrode, a battery control unit for controlling the electric power supplied from the battery to the power supplying electrode, a battery signal electrode for receiving the on-manipulation signal, and a power supplying unit for starting a power supply from the battery to the battery control unit when the battery signal electrode receives the on-manipulation signal.
