Grounding contact pin 214 includes an extension portion that can move and extend out from a side of body 202 configured to face ground lug 102. The extension portion of grounding contact pin 214 can also move and retract back into the side of body 202 configured to face ground lug 102 (which in turn pushes out the opposite handle side end of grounding pin 214 from body 202). Grounding contact pin 214 is spring loaded using spring 220 that applies a force to push grounding contact pin 214 against ground lug 102. Thus the force applied by the grounding contact pin 214 against ground lug 102 pushes on ground lug 102 that in turn is pushed against panel portion 402 to ensure better contact between panel portion 402 and ground lug 102.

Although the foregoing embodiments have been described in some detail for purposes of clarity of understanding, the invention is not limited to the details provided. There are many alternative ways of implementing the invention. The disclosed embodiments are illustrative and not restrictive.
