An item which performs electrical switching functions by mechanical actuation resulting from changes in atmospheric pressure. Usually consists of an aneroid diaphragm mechanically linked either to a contact joint which opens and/or closes electrical circuits, or to a contact arm which slides over a commutator whose separate segments are connected to electrical circuits used in radio signal modulation. Excludes switch, pressure.
