Abstract

A RFID linking device-based switchable sensor can be used to detect an unseated condition of one component with another component. The switchable sensor includes a RFID linking device, such as a RFID tag, with an electrical circuitry mountable on the one component and a switchable device incorporated with two portions of the electrical circuitry physically and electrically separated from one another such that the switchable device is exposed and normally in a first condition disabling the RFID linking device to a communicatively unavailable state. The switchable device is accessible from externally of the switchable sensor and thus switchable to a second condition, due to contact with an actuator element on the other component, enabling the RFID linking device to a communicatively available state in response to the one component being placed in the seated condition with the other component.
