Abstract
A power tool is provided which accommodates interchangeable tool heads. The power tool includes: a tool body having a housing and an electric motor mounted within the housing, as well as a tool head that releasably attaches via a mechanical connection and an electrical connection to the tool body. The tool releasably connects to the output shaft of the electric motor when the tool head is attached to the tool body. A tool switch interposed between a power source for the electric motor and the electric motor is operable to supply power from the power source to the electric motor. A tool accessory switch interposed between the tool accessory and the power source for the electric motor is operable to supply power from the power source via the electrical connection to the tool accessory, thereby providing the tool operator independent control of the tool accessory.
