HVAC switches most commonly are used to regulate functions like airflow, temperature, and pressure levels within HVAC systems. Some switches are essential to safety, and trigger shutdowns or alerts if operating limits have been exceeded. Some switches are essential to system sequences like start-up and shutdowns. Generally, HVAC switches protect HVAC systems from overheating, pressure buildup, or electrical faults. They ensure efficient operation and help make systems compliant with building codes.
Broken switches can cause HVAC systems to have unsafe operations, failure to start, unexpected shutdowns, poor airflow or temperature control, and can even cause damage to other more expensive components like motors, fans, and control boards. All HVAC switches are subject to wear so they should be routinely inspected, and may require replacement if damaged or if readings are inaccurate.
