Portable electric working machine

摘要

A portable electric working machine of the present invention includes a motor case portion housing an electric motor, a working portion driven by the electric motor, a handle connected to the motor case portion or the working portion and a power source switch disposed within a grip portion of the handle. Electric power is supplied to the electric motor through the power source switch. A spark-preventing capacitor accommodated within the motor case portion is interposed between a pair of terminals of the electric motor. The portable electric working machine of the present invention does not require a large-sized grip portion of a handle, and can prevent a locking of contacts of a power source switch due to contact transition by preventing sparking between the contacts so that a small-sized microswitch can be used.
