Lennox 36K14 Auxiliary Limit Switch 150OPN 140Cls

The Lennox 36K14 Auxiliary Limit Switch 150OPN 140Cls is a security component which was specially developed to enhance the functionality of HVAC systems. This switch is a safety device that controls and measures the temperature of heating apparatus such as furnaces and heat pumps. If the temperature goes beyond the optimal working conditions, the switch stops the circuit and thus the risks of damage. The Auxiliary Limit Switch work at precise temperature; the switch triggers at 150°F and resets at 140°F in order to meet the need for efficient temperature regulation as well as safety measure.
