Abstract
A back-lit push button array which permits close spacing of the buttons while preventing light leaks between the buttons. The buttons are individually keyed into the outer shell of a housing to provide lateral support while permitting axial movement, and interleaving laterally extending features are formed on juxtaposed sidewalls of the buttons within the housing to prevent interbutton light leaks. This permits the buttons to be spaced very closedly, and there is no limitation on the size of the symbols or legends other than the dimensions of the button face itself.
