ABSTRACT:
A foot operated control for electrical circuits that includes a foot rest, and at least one switch that is housed and mounted in a recess formed in a selected portion of the foot rest. The foot rest having a selected profile defining a horizontal portion and at least one inclined portion. A pivoting axis is formed at an intersection of the horizontal portion and the inclined portion adjacent thereto. The switch is actuated as and when the foot rest portion is tilted in a selected direction about the pivot axis so that an operator of the switch contacts a supporting surface or floor. The foot control may be configured for controlling multiple distinct circuits by way or a corded or cordless operation. This foot control may include elastomer boots or an elastomeric covered bottom cover for providing environmental protection. Preferably, the foot control includes a safety interlock, for minimizing the accidental actuation of the circuits when an operators foot is not present.
