1. A variable-force contact comprising:
- a housing;
a barrel extending laterally and having a rear portion and a front portion extending from a front of the housing;
a plunger in the barrel, the plunger having a contacting surface, the plunger able to move laterally within the barrel;
a contact magnet in the barrel between the plunger and the rear portion of the barrel, the contact magnet able to move laterally within the barrel; and
a shuttle magnet on at least a first side of the barrel, the shuttle magnet able to move laterally within the housing.

Abstract
Variable-force contacts that may provide a large and stable contact force in a mated state, may provide a large difference in contact force between the mated and an unmated state, and may reduce stray flux in an unmated state. Examples may replace physical springs with magnetic force for improved reliability. These examples may position the magnets to reduce stray flux in an unmated state.
