Abstract
An electronic module is provided including: a circuit board including conductive pads and a sense pad coupled to an output signal; an actuator having a wiper member accommodating a conductive wiper, the wiper having a first end arranged to slidably engage the sense pad and a second end arranged to slidably engage at least one of the conductive pads; and at least one gap disposed to partition the sense pad into segments along an axial movement path of the conductive wiper, the segments being electrically connected to each other to have the same electric potential.
