The following list contains the part numbers of all the small pieces used to make up a push-button used in the North American Operators Panel. There are a number of different ways the buttons can be ordered. This is an attempt to make things a little less painful when trying to find the Part Number. Complete Push-buttons can be ordered by using the appropriate number in the part number column. In addition, individual pieces of the button can be ordered using the numbers in the Pieces Column.
