Description
The Lennox 73K20 Auto Limit Switch is an essential safety control device that is applied in the HVAC systems with efficacy for the management of temperature. This auto limit switch is specifically designed for furnaces and works by either making or breaking the electrical circuit as soon as the temperature hits the range of 130-160°F. When the system temperature rises to the designated limit, the switch opens the circuit and turns off the heat while protecting the entire system against heat build-up.
