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 arranged on a control circuit board disposed at a distance from the power circuit board inside the housing. A user-actuated input unit of the electronic power apparatus includes a variable-speed actuator having a first portion at least partially arranged outside the housing to be engageable by a user and a second portion movably arranged between the power circuit board and the control circuit board.
