Abstract: A switch is provided including an actuating body and a base where the actuating body is movably disposed upon the base, the actuating body has an arcuate shape delimited by generally parallel arc edges joined at their ends by curved edges, the actuating body includes an upper surface which inclines in a direction from a concave side of the arcuate shaped actuating body to a convex side thereof, and the actuating body is configured to pivot in a direction toward at least one of the end curved edges.

Abstract: A hand operable switch includes an operating knob that is movable longitudinally or rotationally about a longitudinal axis of the hand operable switch. The operating knob is accessible from any circumferential location of the hand operable switch. A housing includes switching elements wherein movement of the operating knob moves an activation rod relevant to the switching elements for activating a switching element that corresponds to movement of a controlled device. A converter converts the hand operable switch into a foot operable switch.

Abstract: A foot switch which comprises a housing member defining a hollow cavity bounded by front, back and side walls with a pair of spaced apart rib members within the housing spaced intermediate the side walls. Journaled between each side wall and a rib are generally U-shaped members having a first treadle and a second operating arm. The second arms are journaled in the housing and one of the ribs and the first treadle arms are accessible without the housing and adapted to rotate the first arms upon application of pressure. A torsion spring is positioned about each of the second arms between a side wall and a rib and arranged to bias the second arms into a predetermined position. At least one switch having an actuating arm is secured in the housing member. Switch arm actuating members are also secured within within the housing to act on the switch arms and are actuated by the second arms of the U-shaped members when the first arms are depressed under foot pressure.
