Abstract
Disclosed is a pressure switch that utilizes a dome switch having a flange surrounding the dome. The flange is anchored to a substrate such that the dome portion is in contact with a contact pad on the substrate. A pressure medium applied through passageways in the substrate flexes the dome in an elastic manner so that the dome does not contact the contact pad. When the pressure medium falls below a predetermined threshold level, the dome expands and contacts the contact pad to complete a circuit that indicates that the pressure of the pressure medium has fallen below the threshold level.
