Patent ID: 6843578

Claim:
A light display for footwear, said light display comprising: an electro-luminescent (EL) light strip having a mount to a surface of a footwear article; an electronic circuit having a mount in the footwear article; said electronic circuit having a battery to power the EL light strip; a pressure switch assembly having a conductive plate and a non-conductive plate; a conductive coiled spring connected between the conductive and non-conductive plates; said spring having an insulated section adjacent the non-conductive plate; said insulated section having an outer conductive sleeve which contacts a contact plate mounted to the non-conductive plate; wherein the coiled spring is insulated from the non-conductive plate; a central coil of the coiled spring having a conductive surface which contacts the outer conductive sleeve under a pressure between the conductive and the non-conductive plates, thereby completing a circuit from the conductive plate, through the coiled spring, through the outer conductive sleeve to the contact plate; and wherein the pressure switch powers the electronic circuit as a user steps on the footwear article.
