Abstract
A floating key finder is disclosed which includes a housing which is buoyant and has a key ring attached to the housing and designed to hold a plurality of keys. An electrical circuit is contained within the housing and includes a moisture sensing switch which is enclosed when immersed in liquid. Such immersion causes activation of a signal such as a flashing light, an audible horn or beeper, or both.
