Abstract: An illuminator assembly is disclosed which is formed from a light emitting diode (LED) having two electrode pins extending therefrom which are cut to predetermined lengths. One lead then is formed to provide a circularly shaped spring support base and the other lead is bent to provide an attachment potion extending through the center of the opening formed by the spring support base. A capture spring of conical configuration then is attached to the centrally disposed lead which extends through the spring support base opening. A compressible coil switching spring then is attached to the spring support base. The assemblage thus formed is employed with a battery of a variety having a forward face which engages the free end of the switching spring and which includes a rod shaped electrode extending from the center portion thereof.
