This premium 3/4-inch disc limit switch is an essential safety component designed for high-limit control in heating and HVAC systems. As an automatic reset thermal switch, it acts as a critical fail-safe by monitoring internal temperatures to prevent overheating. When the temperature reaches its 240°F threshold, the switch opens the circuit to interrupt power, and it automatically resets once the temperature drops by 70°F. Built for durability and precision, this fan disc switch is a common replacement part for malfunctioning thermal cut-offs in residential and commercial appliances, ensuring your equipment operates within safe thermal parameters and protecting against potential system damage.
