ABSTRACT:
A portable electric tool has a housing, an electric motor energized by a trigger-actuated switch, and a receptacle recessed in the housing. Terminals of the switch are formed as plug prongs which extend outwardly directly from the switch housing into the receptacle for receiving the female connector of a power supply cable. Preferably, a second set of plug prongs extend forwardly from the switch housing and receive a female connector of a motor cable. This arrangement enables wiring connections to the switch from the supply cable to be eliminated.
