This automatic reset disc limit switch is a vital safety component designed for HVAC systems and residential furnaces. Functioning as a high-limit control, it monitors internal temperatures to prevent the appliance from overheating. When the temperature reaches its 150-degree threshold, the switch opens to interrupt the heating cycle, protecting the unit from potential damage. Once the system cools by the specific 40-degree differential, the switch automatically resets to restore operation. This durable, snap-action disc switch is a common replacement part for gas and electric furnaces, ensuring safe and efficient heating performance.
