Description
The Lennox 80W58 is a pressure switch used in furnace and air handler equipment. It’s a safety guard that monitors air pressure in the system. It switches circuits when activated by preset pressure levels. Example: If the pressure becomes too much, the switch will turn off power to the compressor so that it doesn’t do damage. The Lennox 80W58 is a single pole, single throw (SPST) normally open (N.O.) contact configuration. In simpler terms, the pressure must reach a specific setpoint before the circuit closes, or is open by default. This design guarantees the system is safe and efficient. The Lennox 80W58 is a compact design that makes it easy to install.
