ABSTRACT:
A power tool includes an internal wiring structure having a first terminal board secured to a commutator motor stator and a second terminal board releasably engaged with the first terminal board to electrically connect terminals on the first and second terminal board. The second terminal board includes first and second conductive resilient brush terminals respectively resiliently engaged with first and second conductive brush holders when the stator is installed in a housing of the power tool. Internal wiring of the power tool is thereby automatically completed upon installation of the stator in the housing.
