A system for labeling a button in the field includes a label defining a peripheral boundary and a label-receiving surface defined by the button and adapted for receipt of the label. The label-receiving surface of the button defines a perimeter adapted to accommodate the peripheral boundary of the label. The button includes side and end portions defining raised edges or lips that define the label-receiving surface. The side and end portions serve to align the placement of the label. The side and end portions also protect the edges of the label against accidental dislodgement and peeling. The label typically has a suitable button identifier such as text, or a graphical design element such as an icon, printed thereon.
