Lennox 49L95 Auto Limit Switch 95°F-125°F

The Lennox 49L95 is a limit switch that is automatic in its operation and is used in several HVAC systems. The electronics used are protected by this action and the system is stopped if the temperature rises beyond a particular limit, usually 95°F – 125°F. The switch feels the presence of a damper or any other component and measures the temperature changes, and then sends a signal to the control system. This signal results in the system to perform some action such as turning off the furnace to avoid overheating. Designed for high reliability in extreme conditions, the Lennox has a standard 24V power input,
