A "slip-joint" type of sensor having a tab design consisting of a unique shape which permits easy manufacture, low resistance to sliding forces, and reliable electrical contact. The unique switch or tab and body design provides positive electrical contact without the need for costly, full diameter, annular sheet metal rings. The sensor body lies in a single common plane and may have a variety of shapes depending on the flow rate to be permitted without tripping the sensor. The sensor may be hermetically sealed by a thin-film polymer liner to permit no flow through the sensor without a signal. The liner may be on either or both sides of the sensor. This design permits use of the liner designed to withstand a static pressure without bursting. At the static pressure, however, the liner will be deformed sufficiently to trip the sensor.
