York S1-2845-3171 Auto Limit Switch 95°F-105°F

The York S1-2845-3171 Auto Limit Switch 95°F-105°F is an auto protection part that provides a means of protection to a HVAC system by stopping it from operation when the temperature reaches a certain level. This is to avoid overheating the equipment and other related problems. it has a component that changes its dimensions with the change in the temperature of the environment. When temperature rise to the upper limit of 105°F in this case, the element mechanically turns off the switch and breaks the electrical circuit to stop the system. On the other hand, when temperature drop below the lower limit, the element reduces in size and opens the circuit to enable the system to work again.
