Abstract
An ergonomic footswitch having a substantially planar tiltable treadle positioned on a base enables up and down or pitch movement of the footswitch around an axis of rotation located on the horizontal rotational axis of an operator's ankle. This arrangement reduces fatigue in the operator's leg and ankle and also permits the operator to vary the speed of an instrument or vary an operational parameter of the instrument via both the up and down motion of the treadle.
