Abstract

A power contact as disclosed herein may include first and second conductive plates positioned parallel to each other. Each of the conductive plates may include respective first and second curved portions. The first curved portion of the first conductive plate and the second curved portion of the second conductive plate diverge in two opposite directions. Board tails extend in a common first direction from a first edge of the first conductive plate and a corresponding first edge of the second conductive plate. A contact extends from the first conductive plate and the second conductive plate in a third direction that is generally perpendicular to the common first direction and generally perpendicular to the two opposite directions.
