Johnson Controls P10BC-9 SPDT Low-Range Pressure Switch Range Control 3/20PSI Low 1/8", FPT Connection

The Johnson Controls P10BC-9 is a low range pressure switch that is used in HVAC systems. This is done by its ability to check the air pressure and also switch on or off an electrical circuit depending on the setpoints made. This switch is SPDT type and it has pressure range of 3-20 PSI with the factory preset cut-in at 12 PSI, closing an electrical circuit based on setpoints. When the pressure drops to 12 PSI, which is adjustable up to 2 PSI, the switch alters the electrical contacts so you can power equipment using pressure. The P10BC-9 is normally applied in heating and air conditioning systems to control pressure in elements such as compressors, burners, and air handlers.
