York S1-025-41320-000 Limit Switch L140-40F

The York S1-025-41320-000 Limit Switch is a temperature safety control that is applied in HVAC systems with an opening point of 140F and a difference of 40F. Its key use is to cut off an electrical circuit once a given amount of heat is detected in the circuit to avoid overheating. The internal sensing element is activated when the temperature increases and it is deactivated when the conditions are lower than the differential point. It is fixed in the required heat path and connected to the control circuit by wiring.
