摘要： A rotary power tool includes a housing having a motor housing portion and a handle portion extending therefrom. An electric motor is positioned within the motor housing portion. The rotary power tool further includes a trigger switch configured to activate and deactivate the motor. The rotary power tool further includes a non-contact speed selector switch positioned in the housing. The non-contact speed selector switch is configured to adjust a rotational speed of the motor. The non-contact speed selector switch is separate from the trigger switch.

摘要： A potting boat adapted to receive a printed circuit board is described. The boning boat includes a base plate and a plurality of sidewalls projecting from the base plate, a plurality of cooling fins, a recessed portion, and an arm. The plurality of cooling fins are formed on one of the sidewalls. The cooling fins extend laterally outward from the one of the sidewalls. The recessed portion is in a first sidewall of the plurality of sidewalls, and extends laterally inward. The arm has a first end fixed to the sidewall and an opposite, second end not connected with the first sidewall. The arm at least partially overlays the recessed portion to define a void within which electrical wires connected to the printed circuit board are retained proximate the first sidewall.

摘要： A power tool device including a housing, first and second battery pack terminals, at least one bulk capacitor, a pre-charge circuit, and a discharge circuit. The pre-charge circuit includes at least one resistance connected in series with the at least one bulk capacitor, and a pre-charge switch connected in series with the at least one resistance. The pre-charge switch is configured to selectively provide a conductive path to charge the at least one bulk capacitor. The discharge circuit includes a first switch and a second switch connected in series with the at least one bulk capacitor. The first switch and the second switch are configured to be turned on after the at least one bulk capacitor is charged to a DC bus voltage.
