York S1-025-38970-000 Auto Limit Switch 100°F-130°F

The York S1-025-38970-000 Auto Limit Switch is a safety part whose function is to stop the operation of equipment if the temperature rises beyond a certain level. This is to avoid overheating of the system and or damage to the system in general. The switch is used within the temperature range of 100°F and 130°F and contains a temperature-sensitive element that responds to an increase in temperature. When the setpoint is attained, the switch flips off, breaks the circuit, and thereby disables or turns off the equipment. This preventive action helps to avoid expensive additional work, equipment, and material loss of time and possible dangers which may follow from high temperatures.
