This premium 3/4-inch disc limit switch is a vital safety component for high-performance heating and HVAC systems. Engineered as an automatic-reset high-limit control, this thermal switch monitors internal temperatures to prevent overheating in appliances such as furnaces, electric heaters, and clothes dryers. When the temperature reaches its 290°F threshold, the switch opens to interrupt the electrical circuit, protecting the equipment from damage. Once the system cools down by 40°F, the switch automatically resets to restore functionality. This durable fan disc switch is an ideal replacement part for ensuring safe, reliable operation in residential and commercial heating applications.
