ABSTRACT:
A control device has a housing, and structure disposed in the housing is generally operable for switching between a pair of switching modes thereof. A pair of snap action discs arranged in the housing in opposite and engaging relation with each other are operable relatively and conjointly through discrete snap action movements for effecting the operation of the switching structure between the switching modes thereof. A diaphragm-piston assembly is operable generally for transmitting an applied force in only one direction onto the snap action discs to effect the relative and conjoint operations of the snap action discs through their discrete snap action movements thereby to operate the switching structure between the switching modes.
