Abstract
An RF based state indicator for indicating the state of a control device is provided. The RF-based state indicator indicates the position of a control mechanism by using the position of the control mechanism to enable or disable an RF tag. An RF reader acquires RF transmitted data from enabled RF tags and uses the data to indicate or control an operation aspect of a device.
