This solid state indicating pressure switch is a combination of Helicoid pressure gauge and a lens mounted solid state switching elements. A magnet mounted to the gauge pointer activates a hermetically-sealed reed switch at each set point. Upper and/or lower set points normally have capture tabs to prevent the gauge pointer from moving beyond the set points, thus providing a mechanical power-off memory. There is a continuous indication of the process variable between set points. In AC applications the reed switch energizes a triac (solid state switch), while for DC applications he control current is is carried directly by the reed switch. Typical applications include on-off controls of motors, pumps, solenoids, relays, annunciators and alarms.
