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.
