Abstract
A power tool that includes a motor and a printed circuit board (“PCB”). The motor includes a rotor and a stator. The stator includes a plurality of stator terminals. The PCB is electrically connected to the stator. The PCB includes a switch and an embedded busbar. A first end of the embedded busbar is electrically connected to the switch. The embedded busbar extends away from the PCB. A second end of the embedded busbar electrically connects to a stator terminal of the plurality of stator terminals for providing power to the motor using the switch. The embedded bus bar is embedded between two layers of the printed circuit board.
