Abstract
A small dot or disk flip dot display element and a method of making a flip dot display formed of such elements is shown where the disks or dots flip between an ON position showing a bright surface and an OFF position showing a dark surface. The dots are flipped by electromagnets having poles with a first coil wound thereon for producing a reversible magnetic field operating the flip dots. A second coil is wound on the poles in series with the first coil. The second coil is dipped in molten solder to form an electrical contact for energizing the first coils, and for mounting the elements to a circuit board. Separate terminal pins are not required for electrical connections to the coils, thus allowing flip dots as small as 5 mm or less to be used.
