A surgical footswitch, comprising:
- a) a base having a bottom;
- b) a treadle pivotally and rotationally mounted to the base;
- c) a pair of side switches rotationally mounted to the base on either side of the treadle, the side switches being operable without movement of the treadle and adjustable relative to the treadle so as to increase or decrease the distance between the side switches;
- d) a heel cup slidable and rotatably retained on the treadle so as to adjustably increase or decrease a length of the treadle;
- e) a pair of switches mounted to the treadle so that rotation or counter-rotation of the treadle operates the switches;
- f) a plurality of plungers retractably mounted to the bottom;
- and
- g) a relatively high friction material mounted to the base bottom,
- wherein the plungers retract within the base when weight is placed on the footswitch and extend outwardly from the base and the relatively high friction material when no weight is placed on the footswitch.
