HVAC Limit Switch
An HVAC limit switch controls the operation of the system. The switch is typically located in the air ducts or near the air handler and is used to monitor the temperature of the air passing through the system.
When the temperature of the air reaching the limit switch for air Conditioner exceeds a certain preset level, the switch will activate and shut off the system, preventing damage from overheating. Similarly, when the temperature of the air drops below a certain level, the switch will activate and turn on the system.
