• Special Features:
  Standard adjustment rante of pressure difference: 1 - 20 psid, make/break differential - spst; 3 - 9psig, max system pressure (psig): 50, max pres (psib); 80, bellows diameter 1 - 3/8", 222-32 series switch is intended for use on vessels having an annunciator panel (spec. Mil-a-17196) with a supervisory circuit continuously indicating whether ships wiring between the panel and the alarm switch is in working order. To provide for this feature a navy-approved resistor is connected across the terminal screws.
