The Lennox 80K25 is a pressure switch that is made to be used with Lennox HVAC systems only. It is 0.24 Inches wide and has a (SPST) configuration. This type of switch turns on or off an electrical circuit depending on the pressure variation in an HVAC unit. In simple terms, what the 80K25 does is that it functions as a switch. Through monitoring air pressure, it can cause the system to turn off if the pressure is beyond the standard pressure range. This prevent damage on the compressor and other parts of the equipment.
