Johnson Controls P100AP-9 Pressure Control Switch Open 25 PSI Close 80 PSI 18" Wire Leads

The Johnson Controls P100AP-9 is a miniature, yet robust pressure control switch designed primarily to maintain pressure for HVAC systems. This has a relatively simple design of the device, yet it is incandescent. This switch action is normally “Open on Fall”, it means that voltage output is isolated when pressure ramps up to 25 psi. When pressure drops to the earlier level, the disc goes back to the initial position and the switch turns on power. It has eighteen-inch wire leads of P100AP-9 to enhance convenient wiring. Typically used in pressure cut out applications for air compressors or condenser fan cycling on Refrigeration systems or boiler low pressure protection, this switch has an adjustable pressure range of 25 to 80 psi coupled with 1/4” flare fitting.
