Abstract
An air core gauge for an instrument cluster includes a permanent magnet armature and field coils energized according to an input parameter determine the position of the armature and a pointer connected to the armature. Terminal pins outboard of the armature carry energizing current to the coils. One of the terminal pins is made of ferrous material to magnetically attract the armature to a rest position when energizing current is off.
