ABSTRACT:
A foot-operated controller is disclosed herein having a housing enclosing an elongated resistive element carried on the underside of a top panel midway between its opposite sides. The top panel is provided with a slot slidably accommodating an electrical contact in slidable engagement with the resistive element. A foot-engaging treadle is disposed on the top panel from which the electrical contact downwardly depends so as to travel therewith as the treadle moves. The treadle is provided wheeled support riding in a grooved track carried on a bottom panel of the housing. Stops are provided on the opposite ends of the grooves to limit linear movement of the treadle and electrical leads and plugs are included.
