Abstract
An electric working machine of one aspect of the present disclosure includes a connection port, a control circuit, and/or a power supply switch. The power supply switch is provided on a power supply path extending from a battery pack connected to the connection port to the control circuit. The power supply switch maintains an ON state while a power supply permission signal is output from the battery pack to the electric working machine. The control circuit outputs an ON-command signal to the power supply switch for a specified period of time in response to loss of the power supply permission signal from the battery pack.
