York S1-025-29041-002 Auto Limit Switch 120-150°F 3" Insertion

The York S1-025-29041-002 is an essential protective addition for HVAC systems. This automatic limit switch ensures that equipment is reduced in operation when temperatures go high than a given limit. It has an insertion length of 3.0” and works at temperature ranging between 120°F to 150°F. The limit switch which is installed in a protective casing contains a temperature-sensitive component. When the temperature increases, the element gets elongated and this makes the switch to open and therefore switch off the HVAC system. When the temperature comes down, the switch turns off and then turns on again enabling the system to start working. This auto limit switch is normally used in York HVAC products like furnaces, air conditioners, and heat pumps.
