This 3/4" disc limit switch is a high-performance thermal control designed for heating, ventilation, and air conditioning (HVAC) systems. Acting as a critical safety device, this high-limit switch monitors ambient temperature and automatically breaks the electrical circuit when heat levels reach 120°F to prevent overheating in furnaces and unit heaters. It features an automatic reset function, allowing the system to resume operation once the temperature drops by the designated 10°F differential. Ideal for fan control and thermal regulation in both gas and electric heating units, this durable component ensures reliable performance and equipment protection.
