A Temperature Switch used in a radiator shutter is a device that opens or closes a radiator shutter based on the temperature of the engine coolant. The switch is typically located in the engine block and it has two terminals. When the coolant temperature reaches a certain level, the switch closes and sends a signal to the shutter to open. This allows more airflow through the radiator, which helps to cool the engine.Attributes:a— Increases fuel efficiency by reducing the amount of heat that is lost from the enginea— Manufactured to precise specifications and is durable and reliableApplications:A Temperature Switch helps to keep the engine at a cooler temperature, which reduces the amount of fuel that is needed to keep the engine running.
