1. A circuit interconnecting device for a power tool of the type having a compartment for a replaceable battery, the device comprising:

  • a base means adapted for mounting in the battery compartment including power cord receiving means, and extension means receiving means, the base means including power tool asymmetrical engagement means for engaging an asymmetrical receiving means of the battery compartment, said engagement means being engagable with said receiving means only when the device is inserted into the battery compartment in a preferred orientation and otherwise preventing the full insertion of the device into the battery compartment;

    an extension means, having a proximal end and a distal end, the proximal end adapted for plug-in engagement with the extension means receiving means, the distal end adapted for electrical interconnection with a pair of electrical contacts of the power tool, the proximal and distal ends being in electrical communication;

    a power cord including, at one end, a plug for electrical interconnection with a power source socket, the other end adapted for engagement with the power cord receiving means of the base means such that engagement of the proximal end of the extension means with the extension means receiving means provides electrical interconnection between the power cord and the proximal end of the extension means whereby the device may be inserted into the battery compartment of the power tool to provide power from the power source socket to the power tool electrical contacts.
