The actuation electrodes are used to position the spring probe relative to the substrate using electrostatic, magnetic, acoustic, or piezoelectric arrangements. An actuation signal source is switched between full on and off states to facilitate “ON/OFF” probe actuation in which the spring probe is either fully retracted against the substrate or deployed for scan operations. The position sensing electrodes are used to sense the deflected position of the spring probe relative to the substrate using resistive, magnetic, or piezoresistive arrangements. Spring probe arrays are disclosed that include multiple spring probes arranged on a single substrate.
