Abstract
An improved lighted key assembly includes ridges located adjacent to the base and a ledge above the base. An LED, supported by the ledge, has leads which are mounted against the ridges so that an intermediate portion of the leads is bent around the bottom of the ridges. When mounted to the printed circuit board of a keyboard, the intermediate portions of the leads are in physical contact with contact pads on the printed circuit board to pass electrical current from the contact pads, through the leads, to the LED.
