An improved connector lead is described herein that protects components that may be attached to either lead in a connection. The charge dissipates in a resistive member that is physically coupled to a conductive member to form at least in part a first lead.

Abstract: An electrical connector for connecting to ground and first and second signal lines includes a ground contact, a first signal contact, a second signal contact, and a switch connected to the first signal contact and the ground contact. The switch is biased “on” until after the first signal contact is connected to the first signal line, the ground contact is connected to the ground, and the second signal contact is connected to the second signal line.
