How the two windings of a flipper coil work
A flipper coil has a power winding (few turns of heavy wire, low resistance) and a hold winding (many turns of fine wire, high resistance). The power winding kicks the flipper up; once it is cut out at the end of the stroke, the hold winding alone keeps the flipper up without overheating while the button is held.
