An electronic power apparatus is provided, including a circuit board having a conductive pads and a sense pad coupled to an output signal, and an actuator having a wiper portion accommodating a conductive wiper. The wiper includes a first end arranged to engage the sense pad and a second end arranged to slidably engage at least one of the conductive pads on the circuit board. The conductive pads are arranged in a first row of conductive pads and a second row of conductive pads in parallel with and at a distance to the first row of conductive pads. An alignment of the second row of conductive pads is offset with respect to the first row of conductive pads.
