Description
The Bard HVAC 8402-067BX Auto Limit Switch is an essential safety part used in HVAC systems. It is used as an automatic switch to prevent HVAC equipment from overheating. It measures the system’s temperature with an insertion length of 7 inches and a temperature range of 140-170°F. When the temperature goes high, the switch turns off the HVAC unit to protect other parts such as the furnace or heat exchanger. When the temperature drops to a safe level, the switch turns off and then turns on again enabling the system to function again. This automatic function makes certain that the protection is constant and improves the durability of the HVAC equipment.
