Differential pressure
switches for air or liquids
The P74 Series of differential pressure
switches measure the difference in pressure exerted
upon its two sensing elements and operate a SPDT
switch at the differential pressure setpoint.

0.05" W.C. to 12.0" W.C. (12.5 to 2989 Pa)
Low
differential air pressure switches
Switches sense pressure, vacuum or differential pressure in
applications including fan status, pump status, dirty filter monitoring, or
frost build-up on coils.
P10 Pressure Switches
3-20 psig (21-138 kPa) The common terminal is red. The
red-to-yellow terminals close an electrical circuit on a rise in
pressure; the red-to-blue terminals close a circuit on a drop in
pressure. 1/8" NPT with 1/4" barb
