Description
The Lennox 18M10 Limit Switch is a small and light safety device meant for use in Lennox HVAC equipment only. This automatic limit switch has dimensions of length 2 inches, width 2 inches and height 2 inches. It has an SPDT connection type. It is designed to be able to check the temperature inside your system. When temperatures rise beyond its established 160°F, the switch triggers breaking the circuit to halt the system’s operation and avoid high-temperature hazards that can cause decimating effects. There are some models of the limit switch that will reset themselves when the temperatures are below the low limit of forty degrees Fahrenheit and the system can continue to run.
