Switch for data connector jack

A switch for a data connector jack adaptable to receive a plug operating in a high frequency range or a plug operating in a low frequency range therein. The data connector jack is coupled to a cable having a plurality of wires contained therein. The switch has a primary state, an intermediate state, and a secondary state, and includes a printed circuit board having a surface. A plurality of row contacts are mounted on the surface of the printed circuit board and a plurality of bifurcated contacts are spaced apart from the plurality of row contacts and mounted on the surface the printed circuit board. A grounding pad is mounted on the surface of the printed circuit board and a jumper assembly. The jumper assembly includes an insulator pad and a plurality of jumper springs flexibly connected to the insulator pad and in abutting contact with the surface of the printed circuit board such that at least one of the plurality of jumper springs is in abutting communication with the grounding pad when the plurality of jumper springs are in the open position, the transition position, and the closed position to prevent crosstalk among the plurality of jumper springs.
