Reznor 204327 Pressure Switch SPDT

The Reznor 204327 Pressure-Switch SPDT is an essential component of the HVAC systems. Designed to work by monitoring the pressure of air and act correspondingly. The based on a diaphragm mechanism that responds to pressure variations this leads to open or close of electrical contacts within the system. The switch assists in maintaining right air flow and combustion safety. It also enables system to operate when enough pressure is sensed. If the pressure is below or above the set limit, the switch disconnects the circuit to avoid any difficult operation.
