A switch device having a base, a first electrically conductive pad coupled to the base, a second electrically conductive pad coupled to the base, a first electrically conductive projection and a second electrically conductive projection. The second electrically conductive pad is spaced apart from the first electrically conductive pad by a first predetermined distance. The first electrically conductive projection is coupled to the first electrically conductive pad and extends into the first gap. The second electrically conductive projection is coupled to the second electrically conductive pad and extends into the first gap. The second electrically conductive projection is spaced apart from the first electrically conductive projection by a second predetermined distance. The first and second electrically conductive projections form an electrical interface.
