ABSTRACT:
In a foot control, two or more pivoted pedals have a common main spring which provides the same resistance to all pedals. A bias arrangement keeps one pedal from falling down if the other pedal is depressed. A bias arrangement may be a horizontal rod associated with each pedal. The rod is spring biased against the pedal at a location below the pivot axis.
In a two pedal embodiment both pedals can control a single electrical element. A stud extends from each horizontal rod. The stud normally prevents a spring biased pivoted member from pivoting and actuating the electrical element. When a pedal is depressed, the corresponding rod and stud move to allow the pivoted member to actuate the electric element and a corresponding switch.
