Abstract
An improved interface for releasably connecting a power control module or battery pack to an electrical appliance or tool. The power control module includes a power control trigger and provides electrical power to a motor of the appliance. The power control switch is located on the appliance, and is actuated by a portion of the trigger extending through the interface. The interface includes a pair of dovetail connections with interlocking flanges, requiring a two-motion procedure for assembly and disassembly. A latch release assembly interacts with the trigger to avoid powering the motor during assembly, and to prevent disassembly with the trigger pulled.
