An electrical apparatus includes an electrical apparatus main body (100) and a battery pack (200). The electrical apparatus main body (100) has a load (M), a manipulation switch (SW1), a power receiving electrode (Sa1), a main body control unit (13) for controlling the electric power supplied from the power receiving electrode (Sa1) in response to a manipulation of the manipulation switch (SW1), a signal generation unit (11) for generating an on-manipulation signal if the manipulation switch (SW1) is switched on, and a main body signal electrode (Sa4) for outputting the on-manipulation signal. The battery pack (200) has a battery (22), a power supplying electrode (Sb1), a battery control unit (24) for controlling the electric power supplied from the battery (22) to the power supplying electrode (Sb1), a battery signal electrode (Sb4) for receiving the on-manipulation signal, and a power supplying unit (21) for starting a power supply from the battery (22) to the battery control unit (24) when the battery signal electrode (Sb4) receives the on-manipulation signal. |
