Patent ID: 7818864

Claim:
A method comprising: providing a housing assembly with a housing and a circuit board, the housing including a first cavity and second cavity, the first cavity extending through a first end of the housing and having a first longitudinal axis, the second cavity extending through a second end of the housing opposite the first end and having a second longitudinal axis that is not coincident with the first axis and which intersects or is skewed to the first axis so as to form an included angle therebetween that is less than 180 degrees in magnitude, the circuit board being received in the housing and having a switch, a plurality of first terminals and a plurality of second terminals, wherein providing the housing assembly includes forming a pair of housing half shells, assembling the circuit board to a first one of the housing half shells, and coupling the housing half shells to one another; providing a motor assembly having a motor with a pair of motor terminals; sliding the motor assembly into the first cavity to engage the motor terminals to the first terminals; and sliding a battery assembly into the second cavity to engage a plurality of battery terminals to the second terminals to thereby electrically couple the battery assembly to the motor and the switch.
