The Lennox 51W92 Pressure Switch SPST is a lightweight (0.19 lbs) device used in various HVAC systems like furnaces and air conditioners. It acts as a single-pole, single-throw (SPST) switch, meaning it has one set of contacts that open or close depending on air pressure. By monitoring air pressure, the switch triggers electrical components like the furnace or air conditioner to turn on or off when pressure reaches a specific set point (1.00 inch water column for the 51W92 model). This helps maintain optimal airflow throughout the system, ensuring efficient operation.
