Abstract: A handswitch (50) for a powered surgical handpiece (54) comprises a mounting base (62), a lever (70), a spring, a run-safe switch (68) and a lever extension. The mounting base defines a pivot axis. The elongated lever defines a lever axis substantially normal to a direction of the pivot axis. The lever includes a proximal end pivotably connected to the mounting base at the pivot axis and a distal end opposite the proximal end. The first track is on an inner side of the lever. The second track is on an outer side of the lever opposite the inner side, with both tracks substantially parallel to the lever axis. The spring is between the base and the lever and biases the lever about the pivot axis. The run-safe switch is slidably disposed on the first track. The lever extension is slidably disposed on the second track.
