York S1-2940-3161 Fan Limit Switch 105°FOpen/120°FClose

The York S1-2940-3161 Fan Limit Switch is an essential part of HVACR equipment that helps to prevent the failure of the equipment and increase its efficiency. At 105°F the switch breaks the electrical circuit and thus the system is protected from further heating. Conversely, when the temperature gets down to 120°F the switch is turned off and the system returns to normal operations. The temperature regulating system is safe in terms of its on/off cycle of the HVAC system.
