A load cell includes a first element, a second element and a sensor measuring force between the first and second elements along a first axis. The battery frame includes a switch side plate which supports a switch slide plate for movement between an \u201coff\u201d position, a first position enabling momentarily closing of a circuit including the light source and battery pack, and a second circuit closing position to continuously energize the light source in response to actuation of an externally exposed switch push button.
