Description
The Lennox 11J10 0.55-inch Pressure Switch is an essentialpart that is applied in HVAC systems to measure the pressure of the air. This pressure switch senses the changes in the pressure level of the system and is suitable to be used together with heating or cooling systems like furnace or air conditioner among others. When the pressure rises to certain values, the switch turns on or off an electrical circuit, which triggers the operations of the HVAC system. It works perfectly to ensure the better system performance since it does not overheat and has poor air circulation.
