Industrial JD-2-801111303 Spring Pressure Switch

Antunes JD-2-Red 801111303 differential air pressure switch is a compact, die-cast aluminum device with a red spring for precise, adjustable setpoints from 0.1" to 24" W.C. It provides dual 1/8" NPT sensing ports, a visible ON-OFF indicator, and an SPDT snap-action contact rated up to 10 A at 125 VAC for controlling burners and blowers, with auto-reset when the sensed pressure crosses the setpoint. Rated for a maximum surge of 3 PSI and a maximum working pressure of 35" W.C., it operates in a temperature range from -20°F to 140°F. As part of the JD-2 family, the red spring version corresponds specifically to the 0.1"–24" W.C. range, and the enclosure measures about 4.02" in diameter with overall dimensions near 4" wide by 5" tall.
