  • The PA404B is used with suspension-type unit heaters to make the fan circuit when a pressure rise indicates the presence of steam
  • Each model contains an SPST MICRO SWITCH snap-acting switch
  • Sensitive pressure-actuated diaphragm expands or contracts with pressure variations, moving a lever mechanism which operates the snap switch
  • A screw on top of the case allows set point adjustment without removing the cover
