Technical Examples

A self-balancing, no-spin magnetic compass. A described embodiment includes a compass card assembly, a retainer assembly, a pivot assembly, a gimbal assembly, a cup, and a dome. The compass card assembly includes an air chamber which provides buoyancy. The retainer assembly functions with the compass card assembly to retain magnets. The pivot assembly snap-fits into the retaining assembly and contacts the compass card assembly to allow the compass card assembly to pivot about the pivot assembly. The pivot assembly also snap-fits into the gimbal assembly. The base of the pivot assembly is positioned into the cup and the entire compass is secured into the dome, that is filled with a fluid.
