Abstract: An interface for a battery pack and an electrical combination. The interface may include a battery-receiving portion configured to receive a battery pack and including a cavity. The cavity is defined by a pair of sidewalls with rails defining a groove between the rails and a lower surface of the cavity. The rails are stepped or angled along a battery insertion axis and are configured to guide the sliding engagement of a battery pack within the battery-receiving portion.

Abstract: A battery pack including a housing defining an aperture, a first battery cell within the housing, a second battery cell within the housing, and a switch. The first battery cell is electrically connected to a first terminal. The second battery cell is electrically connected to a second terminal. The switch is configured to be in a first position and a second position. The switch includes a user-interface, that may extend through the aperture, and a plate, located within the housing. The plate includes a conductive portion and a non-conductive portion. The conductive portion is configured to electrically connect the first terminal to the second terminal when the switch is in the first position. The non-conductive portion is configured to galvanically isolate the first terminal from the second terminal when the switch is in the second position.

Abstract: A power tool includes an outer housing having a drive unit support portion and a handle portion, an inner housing positioned at least partially within the handle, and a drive unit positioned in the drive unit support portion. The drive unit includes an output shaft extending at least partially through the handle portion. The power tool also includes a ball screw mechanism having a nut supported at least partially within the inner housing and a screw coupled to the nut for relative axial displacement therewith in response to relative rotation between the screw and the nut. Torque from the output shaft is applied to one of the nut and the screw to cause the relative rotation. The handle portion exerts a reaction torque on the inner housing in response to the relative rotation between the nut and screw to prevent the inner housing from rotating relative to the outer housing.
