Patent attributes
A display apparatus for lighted footwear, having a spring switch, a battery-powered integrated circuit sealingly encapsulated, a plurality of illuminators, and a wiring harness connecting the illuminators to points of the integrated circuit, the integrated circuit being configured for activating the illuminators in a sequential pattern that can include repeated activation cycles when the spring switch is subjected to an effective acceleration. The display apparatus preferably includes the battery being sealingly encapsulated together with the spring switch and the integrated circuit; an ON/OFF switch can be included for selectively producing a deep sleep state of the integrated circuit that is unresponsive to the spring switch. Also disclosed is footwear incorporating the display apparatus, wherein the encapsulated enclosure is located within a sole heel portion of the shoe, and the illuminators are distributed on the footwear for external view. A switch circuit structured and arranged for use in a lighted footwear display apparatus, the switch circuit comprising: an IC chip, a manual switch, and a pull-up resistor; wherein the IC chip has an IO port, a power source positive electrode and a ground terminal, one end of the pull-up resistor is connected to the power source positive electrode of the IC chip, another end of the pull-up resistor is connected to the IO port of the IC chip and one end of the manual switch, and another end of the manual switch is connected to the ground end terminal of the IC chip. The switch circuit can work normally when the manual switch is located in the water.
