ABSTRACT:
A safety mechanism in a cigarette lighter that utilizes a multi-button system: a button and a button cover. The button has at least two elevations and is placed adjacent to the button cover. The button cover is coupled to one of the elevations of the button. A blocking element limits the downward movement of the button cover sufficiently to prevent activation of the piezo unit. To operate the lighter, the user must apply pressure to the button to operate release fuel and to operate the piezo unit to generate a spark.
