Claims

[Scope of Claim for Utility Model Registration] (1) In a wiring device that forms a wiring circuit network by arranging conductors such as printed wiring or lead wires and fixing a power switch on a board that forms part of a wiring circuit. A wiring device for a power tool, characterized in that a circuit formed on a board and a terminal of the power switch are electrically connected to each other by a screw that tightens and fixes the power switch to the board. (2) In claim 1, when the power switch is fixed to the circuit board, the circuit board must have a hole through which the headless screw provided at the power switch terminal can be attached and removed in order to connect and secure the lead wire of the power cord. A power tool wiring device featuring:
