Honeywell L404F1235 SPDT Pressuretrol Controller 20-300 PSI Snap Action 20-50 PSI Differential

The Honeywell L404F1235 Pressure Switch that is used to measure pressure within systems that range between 20 and 300 PSI. It used an SPDT snap-action mechanism, which ensures fast and definite switching. The switch is set to close at 20 PSI and will reset at 50 PSI below the closing pressure, which is a better hysteresis for the switch to work on. This strong controller is used in numerous applications that need accurate pressure regulation, such as HVAC systems, industrial processes, and fluid power systems.
