{"product_id":"543-500","title":"543-500","description":"The Camstat 3-inch adjustable limit switch is a vital safety component for HVAC systems and furnaces. Designed to function as a high limit control, this switch monitors the temperature within the heating plenum or heat exchanger to prevent the appliance from overheating. With an adjustable range between L120 and L250 degrees Fahrenheit, it provides flexible protection for a wide variety of heating applications. When the internal temperature reaches the set threshold, the switch automatically breaks the electrical circuit, shutting down the heating source to ensure safe operation and prevent equipment damage.
