Abstract
A thin, disposable key light device that is adhesively attachable to the head of a key includes a light emitting diode, a disk battery, an insulative annular spacer, and an adhesive disk. A lead of the light emitting diode extends over a hole in the annular spacer. Leads of the light emitting diode straddle the battery and annular spacer. Switch actuation pressure applied to a flexible housing elastically deforms one of the leads through the hole in the annular spacer, causing that lead to electrically contact one electrode surface of the battery and thereby connect the light emitting disk in series with the battery.
