Abstract
A multiple contact fluid pressure switch includes a plate from which a rib extends to establish a cavity on the plate. Two lower contacts are on the plate within the cavity. A diaphragm is disposed on the rib to enclose the cavity. Further, an upper contact is disposed on the diaphragm directly above the lower contacts. The multiple contact fluid pressure switch is movable between an open position wherein the upper contact does not engage the lower contacts, a first closed position wherein the upper contact engages one lower contact, and a second closed position wherein the upper contact engages both lower contacts.
