Abstract
A power tool includes a housing having a motor housing portion and a handle portion. A motor having a motor axis is positioned within the motor housing portion. The power tool further includes a first printed circuit board positioned within the motor housing portion. The first printed circuit board intersects the motor axis. The power tool also includes a second printed circuit board positioned within the motor housing. The second printed circuit board intersects the motor axis. The second printed circuit board includes a conductive high impedance trace that is configured to interrupt electric power to the motor in response to a current that exceeds a current limit.
