Document Type and Number:
Japanese Patent JP3230936
Kind Code:
B2
Abstract:
PURPOSE: To provide the subject machine designed to effectively prevent lockings due to contact point transition through removing sparks generating between the contact points of an electric source switch without involving larger handle grip even if there is used a small-sized microswitch as the electric source switch.
CONSTITUTION: This hand electric working machine has a motor case 12 holding an electric motor 20, a working part 13 to be driven by the motor 20, and a handle 22 connected to the motor case 12 or the working part 13, and is designed to supply electric power, via an electric source switch set up in the grip 24 of the handle 22, to the motor 20.
