The Lennox NCO-63W57 Pressure Switch is designed for industrial applications. This Pressure Switch has a pressure range of .55/.95wc SPST, responding to pressure changes as low as .55 inches of water column and up to .95 inches of water column. The Lennox NCO-63W57 Pressure Switch is designed to switch electrical circuits on or off based on the pressure of the medium it is monitoring. The switch is a single-pole, single-throw (SPST) type, meaning it has one set of input terminals and one set of output terminals. The switch is normally open, meaning that the circuit is open when the pressure is below the set point. When the pressure reaches the set point, the switch closes, completing the circuit.
