Abstract
An electronic power apparatus includes a housing, a pair of input power pins and a pair of output power pins, and power components mounted on a power circuit board and electrically connected to the input power pins and the output power pins to modulate a supply of power from the input power pins to the output power pins. A control unit of the electronic power apparatus is disposed at a distance from the power circuit board and substantially parallel to the power circuit board, both the control circuit board and the power circuit board arranged inside the housing. A user-actuated input unit is provided including a variable-speed actuator a first portion of which is at least partially arranged outside the housing to be engageable by a user and a second portion of which is slidably sandwiched between the power circuit board and the control circuit board along an axis substantially parallel to the power circuit board and the control circuit board.
