Abstract: An electric working machine may include a control device configured to control an electric unit, an operation member, a first switch configured to be operated by the operation member, and a second switch configured to be operated by the operation member. The operation member may pass a second position and a third position while the operation member moves to the first position. The first switch may be configured to transmit a first signal which changes as the operation member moves from the second position to the first position to the control device when the operation member moves between the second position and the first position. The second switch may be configured to transmit a second signal to the control device when the operation member passes the third position. The control device may be configured to control the electric unit based on the first signal and the second signal.
