An indicator device for proving an announcement of the status of a burner control knob, A base plate attaches to and rotates with a burner control shaft on a stove. An attitude sensing switch mounted with the base plate changes its conductive state when a burner control shaft moves from an “off” position. An annunciator senses the change in conductive state to initiate an announcement of that event.
