An exemplary terminal system comprises a pin-receiving member having a lead-in for receiving a pin-shaped contact, a signal transfer zone located a first distance from the lead-in, and a power transfer zone located a second distance from the signal transfer zone. The signal transfer zone is preferably defined by opposed bumps plated in gold. The power transfer zone is preferably annular in cross-section, so as to present a large contact area, and tin-plated. The system is therefore useful for either signal transfer or power transfer applications.
