Abstract
A push button for a vending machine. The push button includes a lens that is depressed by the customer. Under the lens is a transparent or semi-transparent flexible cover over a plurality of light emitting diodes (LEDs). The color and arrangement of the LEDs can be varied to provide a number of different indicating modes. The present invention does not require items in conventional push buttons, for example, a letter and symbol plate or a reflector case.
