Abstract
A latching power switch for a light emitting diode (“LED”) flashlight is disclosed which includes a vessel comprising upper and lower components for receiving and containing a lithium cell battery, a means of using the anodic and cathodic leads from the LED, an aperture provided through the said vessel, and a switching mechanism comprising a rotating cam movable through the vessel aperture. The switching device comprises an on-off switch. The switch operates by rotating a biwire LED in which its leads are formed to surround a lithium coin cell power source. The LED wire leads pass through holes in an electrically nonconductive cam which has both a protuberance for operating the cam and a lobe for latching against a surface of the aperture through which it passes. The cam latches the wire leads against their proper corresponding coin cell surfaces thus activating the circuit and causing the illumination of the LED.
