ABSTRACT:
A garbage disposal switch assembly having a unique dishwasher air gap body having a vertically oriented upper tubular portion, a first lower tubular portion and a second lower tubular portion. An air tube extends upwardly through, the upper tubular portion and is connected to the bottom end of a bellows mounted in a tubular sleeve supported on the upper tubular portion. The bottom end of the air tube is connected to an air switch positioned electrically in series between a garbage disposal and the source of electrical power for operating the garbage disposal. The air switch is mounted in an electrical box housing in the interior of a cabinet beneath the kitchen sink. An outer cap telescopes over the bellows and the upper tubular portion. The outer cap can be rotated to a selected position that allows it to be depressed thereby causing the bellows to be depressed which in turn actuates the air switch and results in the garbage disposal being operated. The dishwater air gap body is installed through the existing aperture in the top of the sink thereby allowing the garbage disposal to be conveniently turned on and off.
