Abstract: A signaling device is actuated for a limited period of time if a toilet seat cover is not promptly lowered following flushing of the toilet. In the preferred form, an electrically operated signaling device is coupled to an electrical power source through a magnetically actuated switch at the front of the toilet tank and also through a second switch. A magnet fastened to the seat cover closes the magnetically actuated switch when the cover is in the raised position and movement of a float in the toilet tank in response to flushing closes the second switch for a limited period following initiation of flushing. The device reminds users of the toilet to close the cover. This avoids discomfort to a subsequent user of the toilet and assures that small children and pets are blocked from the toilet bowl.
