1. A system for implementing surgical procedures comprising:

  • an ultrasonic surgical handpiece having an end-effector;

    a generator console for controlling the handpiece;

    an electrical connection connecting the handpiece and the console, wherein the console sends a drive current to drive the handpiece which imparts ultrasonic longitudinal movement to the end-effector; and

    a finger-operated switch provided on a housing of the handpiece, the switch activating the handpiece at a first power level if a sensor monitored pressure value on the switch reaches a high threshold, deactivating the handpiece if the sensor monitored pressure value reaches a low threshold, and provides its switching functionality according to a lagging effect as the monitored pressure on the switch is changed, and the hand piece operating at a level proportional to the sensor monitored pressure value on the finger-operated switch.
