# AWS::IoTFleetWise::SignalCatalog Actuator
<a name="aws-properties-iotfleetwise-signalcatalog-actuator"></a>

A signal that represents a vehicle device such as the engine, heater, and door locks. Data from an actuator reports the state of a certain vehicle device.

**Note**  
 Updating actuator data can change the state of a device. For example, you can turn on or off the heater by updating its actuator data.
