The Bradford White 415-43676-02 Manual Reset Limit Switch L270F is a thermal safety control that is used in HVAC systems to stop operation when the temperature reaches 270°F. Its main purpose is to create an electric circuit when the temperature reaches the required limit and avoid excessive heating of the heat exchange zone. It is done by placing the switch close to the hot area with wiring being run into the control circuit. It halts system operation during unsafe temperatures and needs a manual reset after activation during operation.
